Answer:
#include <iostream>
using namespace std;
int main()
{
int grade;
cout << "Enter student's grade: ";
cin >> grade;
switch (grade)
{
case 100 ... 1000:
cout << "That grade is a perfect score. Well done.";
break;
case 90 ... 99:
cout << "That grade is well above average. Excellent work.";
break;
case 80 ... 89:
cout << "That grade is above average. Nice job.";
break;
case 70 ... 79:
cout << "That grade is average work.";
break;
case 60 ... 69:
cout << "That grade is not good, you should seek help!";
break;
default:
cout << "That grade is not passing.";
break;
}
return 0;
}
Explanation:
*The code is in C++
First, ask the user to enter a grade
Then, check the grade to print the correct message. Since you need to check the ranges using switch statement, you need to write the minimum value, maximum value and three dots between them. For example, 70 ... 79 corresponds the range between 70 and 79 both inclusive.
Finally, print the appropriate message for each range.
Note: I assumed the maximum grade is 1000, which should more than enough for a maximum grade value, for the first case.

Define the following terms, as they pertain to website planning: goals, objectives, target audience, and purpose statement. Explain the influence on society of inexpensive Internet access and access to the web.
Answer:
Please see explanations below
Explanation:
Goals; These are the outcomes that a website planning intends to achieve within a stipulated time, i.e weeks, months or years.
Objectives; These are the methods taken, through which the website planning goals will be achieved.
Target audience; These are the specific group of people that are intended to be reached for the website planning. The targeted audience could be identified based on age range, academic background or qualification, gender or marital status.
Purpose statement; This refers to an explanation of the website's planning goals, which is formally written and also shows the main objectives identified with the goals.
The Influence on society of inexpensive internet access and access to the web are numerous; yet it provide information that are not readily accessible by individuals before using the internet. For information to be accessed through internet access by all and sundry, it must come at little or no cost, which is what is currently obtainable in most part of the world.
Moreover, inexpensive access to the internet and web also improve quality of knowledge in addition to the existing ones through research, which is mostly done through the internet.
However, there are also downside of inexpensive access to the internet and web which now depends on whichever individuals want. For instance not every information on the website are true or correct. The right thing to be done is to further search and compare several ones until the right one is found.
Write a simple calculator program. Your program should accept as input an expression in the form of: 3 * 2 Use an if / elif ladder style structure to determine what operation needs to be performed on the two numbers. Your program should handle the arithmetic functions Add, Subtract, Multiply, and Divide (Depending on the operator entered).

Which of the following types of attack is the analyst seeing?
A. Buffer overflow
B. Domain hijacking
C. Denial of service
D. Arp poisoning
Answer:
C. Denial of Service
Explanation:
Denial of service error occurs when the legitimate users are unable to access the system. They are then unable to access the information contained in the system. This can also be a cyber attack on the system in which user are stopped from accessing their personal and important information and then ransom is claimed to retrieve the attack. In such case system resources and information are temporarily unavailable to the users which disrupts the services.
In order to place something into a container you must:_______.
a. double-click on the container and type a command.
b. drag the container onto the materials or instruments shelf.
c. double-click on the material or the instrument.
d. click on the material or instrument and drag it onto the container.
Answer:
Option (d) is the correct answer to this question.
Explanation:
The container is a class, data structure, or abstract data type, the instances of which are compilations of many other particles. In several other words, they store objects in an ordered manner that meets strict rules about access. The reviewing information depends on the number of objects (elements) contained therein. To put any material or instrument in the container, it would be easy to select the material or instrument by clicking them and then dragging them onto the container. The other option won't be able to perform the required task.Other options are incorrect because they are not related to the given scenario.
1. Write a program that asks the user to enter a string. The program should then print the following: (a) The total number of characters in the string (b) The string repeated 10 times (c) The first character of the string (remember that string indices start at 0) (d) The first three characters of the string (e) The last three characters of the string (f) The string backwards (g) The seventh character of the string if the string is long enough and a message otherwise (h) The string with its first and last characters removed (i) The string in all caps (j) The string with every a replaced with an e
Answer:
s = input("Enter a string: ")
print(len(s))
print(s*10)
print(s[0])
print(s[:3])
print(s[len(s)-3:])
print(s[::-1])
if len(s) >= 7:
print(s[6])
else:
print("The string is not long enough")
print(s[1:len(s)-1])
print(s.upper())
print(s.replace("a", "e"))
Explanation:
*The code is in Python.
Ask the user to enter a string
Use len method to get the total number of characters
Use "*" to repeat 10 times
Use index, 0, to get first character
Use slicing to get first three characters
Use slicing to get last three characters
Use slicing to get it in backwards
Check if the length is greater than or equal to 7. If it is, use index, 6. Otherwise, print a message.
Use slicing to remove first and last characters
Use upper method to get it in all caps
Use replace method to replace the "a" with the "e"
The program that ask the user to enter a string and print the (a) The total number of characters in the string (b) The string repeated 10 times (c) The first character of the string (remember that string indices start at 0) (d) The first three characters of the string (e) The last three characters of the string (f) The string backwards (g) The seventh character of the string if the string is long enough and a message otherwise (h) The string with its first and last characters removed (i) The string in all caps (j) The string with every a replaced with an e
is as follows:
x = str(input("please enter a string: "))
print(len(x))
print(x*10)
print(x[0])
print(x[0:3])
print(x[-3:])
print(x[::-1])
if len(x) >= 7:
print(x[6])
else:
print("The string is not up to length 7")
print(x[1:-1])
print(x.upper())
print(x.replace('a', 'e'))
The first line ask the user for a string input.
Print length of the user input
Print the user input ten times.
Print the first value of the user input
print the first three string
Print the last three string
Print the reverse of the string
if the length of the user input is greater than or equals to zero, then print the 7th term of the user input.
else it will print that the string length is not up to seven.
Remove the first and the last term of the user input and print the remaining user input.
print the uppercase of the user input.
Replace a with e in the user input.

Give an example of a function from N to N that is:______.
a) one-to-one but not onto
b) onto but not one-to-one
c) neither one-to-one nor onto
Answer:
Let f be a function
a) f(n) = n²
b) f(n) = n/2
c) f(n) = 0
Explanation:
a) f(n) = n²
This function is one-to-one function because the square of two different or distinct natural numbers cannot be equal.
Let a and b are two elements both belong to N i.e. a ∈ N and b ∈ N. Then:
f(a) = f(b) ⇒ a² = b² ⇒ a = b
The function f(n)= n² is not an onto function because not every natural number is a square of a natural number. This means that there is no other natural number that can be squared to result in that natural number. For example 2 is a natural numbers but not a perfect square and also 24 is a natural number but not a perfect square.
b) f(n) = n/2
The above function example is an onto function because every natural number, lets say n is a natural number that belongs to N, is the image of 2n. For example:
f(2n) = [2n/2] = n
The above function is not one-to-one function because there are certain different natural numbers that have the same value or image. For example:
When the value of n=1, then
n/2 = [1/2] = [0.5] = 1
When the value of n=2 then
n/2 = [2/2] = [1] = 1
c) f(n) = 0
The above function is neither one-to-one nor onto. In order to depict that a function is not one-to-one there should be two elements in N having same image and the above example is not one to one because every integer has the same image. The above function example is also not an onto function because every positive integer is not an image of any natural number.
Given input of a number, display that number of spaces followed by an asterisk. (1 point) Write your solution within the existing supplied function called problem2() and run the Zybooks test for it before continuing on to the next problem. Hint: Use the setw() command to set the field width. Alternatively, you could again use a loop.
Answer:
Following is the program in C++ language
#include <iostream> // header file
#include <iomanip> // header file
using namespace std; // namespace std;
void problem2() // function definition
{
int num ; // variable declaration
cout << "Enter the Number: ";
cin >> num; // Read the input by user
cout << "Resulatant is:";
for(int k = 0; k <num; k++) // iterarting the loop
{
std::cout << std::setw(num); // set width
std::cout <<"*"; // print *
}
}
int main() // main function
{
problem2();// function calling
return 0;
}
Output:
Enter the Number: 3
Resulatant is: * * *
Explanation:
Following is the description of program
Create a function problem2().Declared a variable "num" of "int" type .Read the input in "num" by the user .Iterating the for loop and set the width by using setw() and print the asterisk.In the main function calling the problem2().C - Language Write three statements to print the first three elements of array runTimes. Follow each statement with a newline. Ex: If runTimes[5] = {800, 775, 790, 805, 808}, print: 800 775 790#include int main(void) {const int NUM_ELEMENTS = 5;int runTimes[NUM_ELEMENTS];int i;for (i = 0; i < NUM_ELEMENTS; ++i) {scanf("%d", &(runTimes[i])); }/* Your solution goes here */
return 0;}
Answer:
Replace
/* Your solution goes here */
with
printf("%d",runTimes[0]);
printf("%d",runTimes[1]);
printf("%d",runTimes[2]);
Explanation:
The question requires that the first three elements of array runTimes be printed;
The first three elements are the elements at the first, second and third positions.
It should be noted the index of an array starts at 0;
So, the first element has 0 as its indexThe second has 1 as its indexThe third has 2 as its indexSo, to make reference to the first three elements, we make use of
runTimes[0], runTimes[1] and runTimes[2] respectively
Having mention the above;
It should also be noted that array is of type integers;
So, to display integers in C, we make use of "%d";
Hence, the print statement for the first three elements is
printf("%d",runTimes[0]);
printf("%d",runTimes[1]);
printf("%d",runTimes[2]);
C++ Proagram
Write a loop that sets each array element to the sum of itself and the
next element, except for the last element which stays the same.
Be careful not to index beyond the last element. Ex:
Initial scores: 10, 20, 30, 40
Scores after the loop: 30, 50, 70, 40
The first element is 30 or 10 + 20, the second element is 50
or 20 + 30, and the third element is 70 or 30 + 40. The last element
remains the same.
Follow this code
#include
using namespace std;
int main() {
const int SCORES_SIZE = 4;
int bonusScores[SCORES_SIZE];
int i = 0;
bonusScores[0] = 10;
bonusScores[1] = 20;
bonusScores[2] = 30;
bonusScores[3] = 40;
/* Your solution goes here */
for (i = 0; i < SCORES_SIZE; ++i) {
cout << bonusScores[i] << " ";
}
cout << endl;
return 0;
}
Answer:
Replace /* Your solution goes here */
with
for (i = 0; i < SCORES_SIZE-1; ++i) {
bonusScores[i] += bonusScores[i+1];
}
Explanation:
In C++, the index of an array starts from 0 and ends at 1 less than the size of the array;
Using the analysis in the question, the above code (in the answer section) iterates from the index element (element at 0) to the second to the last element (element at size - 2)';
This is to ensure that the element of the array only adds itself and the next element;except for the last index which remains unchanged
The following operation is done in each iteration.
When i = 0,
bonusScores[0] = bonusScores[0] + bonusScores[0+1];
bonusScores[0] = bonusScores[0] + bonusScores[1];
bonusScores[0] = 10 + 20
bonusScores[0] = 30
When i = 1,
bonusScores[1] = bonusScores[1] + bonusScores[1+1];
bonusScores[1] = bonusScores[1] + bonusScores[2];
bonusScores[1] = 20 + 30
bonusScores[1] = 50
When i = 2,
bonusScores[2] = bonusScores[2] + bonusScores[2+1];
bonusScores[2] = bonusScores[2] + bonusScores[3];
bonusScores[2] = 30 + 40
bonusScores[2] = 70
This is where the iteration stops

3.26 LAB: Leap Year A year in the modern Gregorian Calendar consists of 365 days. In reality, the earth takes longer to rotate around the sun. To account for the difference in time, every 4 years, a leap year takes place. A leap year is when a year has 366 days: An extra day, February 29th. The requirements for a given year to be a leap year are: 1) The year must be divisible by 4 2) If the year is a century year (1700, 1800, etc.), the year must be evenly divisible by 400 Some example leap years are 1600, 1712, and 2016. Write a program that takes in a year and determines whether that year is a leap year. Ex: If the input is: 1712 the output is: 1712 - leap year
Answer:
year = int(input("Enter a year: "))
if (year % 4) == 0:
if (year % 100) == 0:
if (year % 400) == 0:
print(str(year) + " - leap year")
else:
print(str(year) +" - not a leap year")
else:
print(str(year) + " - leap year")
else:
print(str(year) + "- not a leap year")
Explanation:
*The code is in Python.
Ask the user to enter a year
Check if the year mod 4 is 0 or not. If it is not 0, then the year is not a leap year. If it is 0 and if the year mod 100 is not 0, then the year is a leap year. If the year mod 100 is 0, also check if the year mod 400 is 0 or not. If it is 0, then the year is a leap year. Otherwise, the year is not a leap year.
A list based on a simple array (standard array implementation) is preferable to a dynamically allocated list for the following reasons.
A. Insertions and deletions require less work.
B. You are guaranteed a space to insert because it is already allocated.
C. You can take advantage of random-access typically.
D You can mix and match the types of the items on the list. E. (b) and (c).
F. All of the above.
Answer:
A. Insertions and deletions require less work.
C. You can take advantage of random access typically
D. You can mix and match the types of the items on the list.
Explanation:
Standard array implementation is a process in which number of items are of same type and index is restricted at a certain range. This is preferable to dynamic allocated list because it requires less work in insertion and deletions. A dynamically allocated array does not use the fixed array size declaration.
NAT ________. allows a firm to have more internal IP addresses provides some security both allows a firm to have more internal IP addresses and provides some security neither allows a firm to have more internal IP addresses nor provides some security
Answer:
NAT provides some security but allows a firm to have more internal IP addresses
Explanation:
NAT ( network address translation) this is a process where a network system usually a firewall assigns a public IP address to an internal computer used in a private network. it limits the number of public IP address a company operating a private network for its computer can have and this is very economical also limits the exposure of the company's private network of computers. the computers can access information within the private network using multiple IP addresses but it is safer to access external information using one public IP address

The term digital divide refers to "the gap between people with effective access to digital and information technology and those with very limited or no access at all." Could you imagine a life without computers and readily-available internet access? The influence of the Internet can be seen as many of our churches now spread the word using high-tech media productions and sophisticated video presentations. Discuss some of factors that influence unequal Internet access for some members of society.
Answer:
Factors Influencing Unequal Internet Access:
1. Age: Children under 10 and adults over 60 do not enjoy the same level of access to the internet. For children 10, their parents restrict their use of the internet. Most adults over 60 lack the interest and competence to utilize access to the internet.
2. Sex: Men usually enjoy better access to the internet than women. While men explore many sources of internet information, women usually restrict themselves to social media, which is usually their favorites, giving the high-level chatting that is involved in social media.
3. Nationality: Access to the internet is not available equally in all the nations of the world. In communist China, there are government-mandated restrictions placed on citizens. In some sub-Saharan African countries, access to the internet is a luxury that many cannot afford and it is not easily available due to lack of basic internet infrastructure.
4. Education is another factor that influences access to the internet. The level of education dictates whether somebody has access or not. Many illiterate men and women who do not value the internet. What you do not value, you do not use. What you do not use is not accessible to you.
5. Income: This is another important factor that influences access to the internet. In some countries, the availability of high-speed network remains unaffordable to the majority of the population. They only have telephone networks to use their internet access, due to the high cost of high-speed digital satellite-based networks. Many people can only access the internet on public WiFis.
Explanation:
According to wikipedia.com, "Internet access is the ability of individuals and organizations to connect to the Internet using computer terminals, computers, and other devices; and to access services such as email and the World Wide Web."
When Designing Application Components, which characteristics of use cases are helpful to define component boundaries? (choose all that apply) a. Must be installed concurrently b. Sharing common data c. Similarities in actors d. Require the same security level e. Triggered by same events f. Have the same pre-conditions
Answer:
b. Sharing common data
c. Similarities in actors
e. Triggered by same events
Explanation:
When Designing Application Components the characteristics of use cases that are helpful to define component boundaries are sharing common data between the users. The second one is similarities in actors. Actors are the users which interact with the application. There should be similarities in the actors that are to be used the application. Last one is triggered by same events. Triggers are basically the events which cause the use case to begin.

2.3 Write a program to prompt the user for hours and rate per hour using input to compute gross pay. Use 35 hours and a rate of 2.75 per hour to test the program (the pay should be 96.25). You should use input to read a string and float() to convert the string to a number. Do not worry about error checking or bad user data.
Answer:
The programming language is not stated; However this program will be written using Python programming language
Comments are not used; See Explanation Section for line by line explanation of the code
hours = float(input("Hours: "))
rate = float(input("Rate per hour: "))
pay = hours * rate
print(pay)
Explanation:
The first line of the code prompts the user for hour.
The input is converted from string to float
hours = float(input("Hours: "))
The next line prompts the user for hour.
It also converts input from string to float
rate = float(input("Rate per hour: "))
Pay is calculated by multiplying hours by rate; This is implemented using the next line
pay = hours * rate
The calculated value of pay is displayed using the next line
print(pay)
When the program is tested by the given parameters in the question
hours = 35
rate = 2.75
The printed value of pay is 96.25
Going to Grad School! In the College of Computing and Software Engineering, we have an option for students to "FastTrack" their way into their master’s degree directly from undergraduate. If you have a 3.5 GPA and graduate from one of our majors, you can continue on and get your masters without having to do a lot of the paperwork. For simplification, we have four undergraduate degrees: CS, SWE, IT, and CGDD – and three masters programs: MSCS, MSSWE and MSIT. For this assignment, you’re going to ask the user a few questions and determine if they qualify for the FastTrack option.
Sample Output:
Major: Frogmongering
GPA: 3.9
Great GPA, but apply using the regular application.
Sample Output #2:
Major: SWE
GPA: 3.3
Correct major, but GPA needs to be higher.
Sample Output #3:
Major: IT
GPA: 3.5
You can FastTrack.
Sample Output #4:
Major: Study Studies
GPA: 0.4

Answer:
The programming language is not stated. However, I'll answer this question using Python programming language.
The program uses no comments; find explanation below
i = 0
while not (i == 4):
print("Sample Run: #"+str(i+1))
Major = input("Major: ")
GPA = float(input("GPA: "))
if not (Major.upper() == "SWE" or Major.upper() == "IT" or Major.upper() == "CGDD" or Major.upper() == "CS"):
if GPA >= 3.50:
print("Great GPA, but apply using the regular application")
else:
print("Talk to one of our advisors about whether grad school is for you")
if (Major.upper() == "SWE" or Major.upper() == "IT" or Major.upper() == "CGDD" or Major.upper() == "CS"):
if GPA >= 3.50:
print("You can FastTrack.")
else:
print("Correct major, but GPA needs to be higher.")
i = i + 1
Explanation:
Line 1 of the program initializes the sample run to 0
Line 2 checks if sample run is up to 4;
If yes, the program stops execution else, it's continues execution on the next line
Line 3 displays the current sample run
Line 4 and 5 prompts user for Major and GPA respectively
Line 6 to 10 checks is major is not one of CS, SWE, IT, and CGDD.
If major is not one of those 4 and GPA is at least 3.5, the system displays "Great GPA, but apply using the regular application"
If major is not one of those 4 and GPA is less than 3.5, the system displays "Talk to one of our advisors about whether grad school is for you"
Line 11 to 15 checks is major is one of CS, SWE, IT, and CGDD.
If major is one of those 4 and GPA is at least 3.5, the system displays "You can Fastrack"
If major is one of those 4 and GPA is less than 3.5, the system displays "Correct major, but GPA needs to be higher."

Who are the users of ATM:
Customers at the bankIndividuals /peopleStaff of the BankA developer is creating an application to track engines and their parts an individual part can be used in different types of engines. What data model should be used to track the data and to prevent orphan records?
Answer:
C
Explanation:
An orphan record are records that have been left out of the new system when a company changes its model of operation since they have no transition path. Therefore the best way to prevent this would be to create a master-detail relationship to represent the one-to-many model of engines to parts. This would allow these records to be captured and reprocessed into the new system that the company has moved to in order for them not to be left out.
The weekly pay for an employee is determined based on the following parameters:
Standard work hours by week is 40 hours.
Hourly pay rate is $10.00 per hour
Overtime hours are paid at time and a half the rate (that is $15.00 per hour).
Design and implement a program (name it WeeklyPay) that read number of hours worked per week (as integer value), prints out the entered hours, and then prints out the gross earning. Organized your output following these sample runs.
Sample run 1:
You entered 20 hours.
Gross earning is $200.0
Sample run 2:
You entered 40 hours.
Gross earning is $400.0
Sample run 3:
You entered 50 hours.
Gross earning is $550.0
Write a loop that reads strings from standard input where the string is either "land", "air", or "water". The loop terminates when "xxxxx" (five x characters) is read in. Other strings are ignored. After the loop, your code should print out 3 lines: the first consisting of the string "land:" followed by the number of "land" strings read in, the second consisting of the string "air:" followed by the number of "air" strings read in, and the third consisting of the string "water:" followed by the number of "water" strings read in. Each of these should be printed on a separate line. Use the up or down arrow keys to change the height.
Answer:
count_land = count_air = count_water = 0
while True:
s = input("Enter a string: ")
if s == "xxxxx":
break
else:
if s == "land":
count_land += 1
elif s == "air":
count_air += 1
elif s == "water":
count_water += 1
print("land: " + str(count_land))
print("air: " + str(count_air))
print("water: " + str(count_water))
Explanation:
*The code is in Python
Initialize the variables
Create a while loop that iterates until a specific condition is met. Inside the loop, ask the user to enter the string. If it is "xxxxx", stop the loop. Otherwise, check if it is "land", "air", or "water". If it is one of the given strings, increment its counter by 1
When the loop is done, print the number of strings entered in the required format
Write a program that prompts the user to enter a hex digit and displays its corresponding binary number. Sample Run 1 Enter a hex digit: B The binary value is 1011 Sample Run 2 Enter a hex digit: b The binary value is 1011 Sample Run 3 Enter a hex digit: T Invalid input
Answer:
I am writing a JAVA program. Let me know if you want the program in some other programming language.
import java.util.Scanner; //to take input from user
public class HexaToBinary{ //class to convert hexa to binary number
public static void main(String[] args) {// start of main() function body
//creates instance of Scanner class
Scanner input = new Scanner(System.in);
//prompts user to enter a hexadecimal number
System.out.print("Enter a hex digit: ");
char hexadecimal = input.nextLine().charAt(0);//reads input from user
String binary = ""; //variable to hold corresponding binary number
/*switch statement is used to convert hexadecimal input to corresponding binary number. the switch statement has cases. Each case has a hexa decimal number. The user's input is stored in hexadecimal variable which is given as a choice parameter to switch statement. If the input matches any of the cases in switch statement, the body of that case is executed which prints the corresponding binary number otherwise invalid input message is displayed in output */
switch (hexadecimal) {
case '0': binary = "0"; break;
case '1': binary = "1"; break;
case '2': binary = "10"; break;
case '3': binary = "11"; break;
case '4': binary = "100"; break;
case '5': binary = "101"; break;
case '6': binary = "110"; break;
case '7': binary = "111"; break;
case '8': binary = "1000"; break;
case '9': binary = "1001"; break;
//here both the upper and lower case letters are defined in case, so the user //can enter a hexadecimal in lowercase or uppercase
case 'a':
case 'A': binary = "1010"; break;
case 'b':
case 'B':binary = "1011"; break;
case 'c':
case 'C': binary = "1100"; break;
case 'd':
case 'D': binary = "1101"; break;
case 'e':
case 'E': binary = "1110"; break;
case 'f':
case 'F': binary = "1111"; break;
default: System.out.println(hexadecimal + " is invalid input"); System.exit(1); } //displays this message if user enters invalid input e.g T
System.out.println("The binary value is " + binary); } }
//prints the corresponding binary number of the hexadecimal input
Explanation:
The program is well explained in the comments mentioned with each line of the program. Lets take an example of user input.
For example if user enters b in input then the cases of the switch statement are searched for by the program to select the corresponding binary number of the input hexadecimal. So b is present in case 'b': case 'B':binary = "1011"; break; So the value of binary is 1011 and this value is displayed on the screen with this statement System.out.println("The binary value is " + binary); So the output is: The binary value is 1011
The screenshot of output and program are attached.

You are working for a small company that has developed an operating system for PCs that is faster and more stable than Microsoft’s Windows operating system. What strategies might your company pursue to unseat Windows and establish its own operating system as the dominant technical standard in the industry?
Answer:
The company could license its technology to Microsoft to exploit Microsoft's size and market
Explanation:
Licencing the technology to Microsoft would take advantage of Microsoft's size and power in the industry. When the technology is widely adopted people will be more willing to switch to the small companies operating system as it will be similar to what the customers are already using.
Write a converter program for temperatures. This program should prompt the user for a temperature in Celsius. It should then convert the temperature to Fahrenheit and display it to the screen. Finally, it should convert the Fahrenheit temperature to Kelvin and display that to the screen.
Answer:
c = float(input("Enter the temperature in Celsius: "))
f = c * 1.8 + 32
