What is a piece of information sent to a function
Answer:
the information sent to a function is the 'input'.
or maybe not hehe
Custom function definitions:________.
A. Must be written before they are called by another part of your program
B. Must declare a name for the function
C. Must include information regarding any arguments (if any) that will be passed to the function
D. all of the above
Answer:
D. all of the above
Explanation:
A option is correct and function definition must be written before they are called by another part of your program. But in languages such as C++ you can write the prototype of the function before it is called anywhere in the program and later write the complete function implementation. I will give an example in Python:
def addition(a,b): #this is the definition of function addition
c = a + b
return c
print(addition(1,3)) #this is where the function is called
B option is correct and function definition must declare a name for the function. If you see the above given function, its name is declared as addition
C option is correct and function definition must include information regarding any arguments (if any) that will be passed to the function. In the above given example the arguments are a and b. If we define the above function in C++ it becomes: int addition( int a, int b)
This gives information that the two variables a and b that are parameters of the function addition are of type int so they can hold integer values only.
Hence option D is the correct answer. All of the above options are correct.
Write a program that takes a three digit number (input) and prints its ones, tens and hundreds digits on separate lines
In python:
number = input("Enter your number ")
i = 0
while i < len(number):
print(number[i])
i += 1

To create a public key signature, you would use the ______ key.
Answer:
To create a public key signature, you would use the _private_ key.
Explanation:
To create a public key signature, a private key is essential to enable authorization.
A private key uses one key to make data unreadable by intruders and for the data to be accessed the same key would be needed to do so.
The login details and some important credentials to access user data contains both the user's public key data and private key data. Both private key and public key are two keys that work together to accomplish security goals.
The public key uses different keys to make data readable and unreadable.
The public key is important to verify authorization to access encrypted data by making sure the access authorization came from someone who has the private key. In other words, it's a system put in place to cross-check the holder of the private key by providing the public key of the encrypted data that needed to be accessed. Though, it depends on the key used to encrypt the data as data encrypted with a public key would require a private key for the data to be readable.

In this exercise you will debug the code which has been provided in the starter file. The code is intended to take two strings, s1 and s2 followed by a whole number, n, as inputs from the user, then print a string made up of the first n letters of s1 and the last n letters of s2. Your job is to fix the errors in the code so it performs as expected (see the sample run for an example).
Sample run
Enter first string

Answer:
Here is the corrected program:
import java.util.Scanner; //to accept input from user
public class 02_14_Activity_one { //class name
public static void main(String[] args) { //start of main method
Scanner scan = new Scanner(System.in); //creates Scanner class object
System.out.println("Enter first string"); //prompts user to enter first string
String s1 = scan.nextLine(); //reads input string from user
System.out.println("Enter second string"); //prompts user to enter second string
String s2 = scan.nextLine(); //reads second input string from user
System.out.println("Enter number of letters from each word"); //enter n
int n = scan.nextInt(); //reads value of integer n from user
System.out.println(s1.substring(0,n) + s2.substring(s2.length() - n ));
} } //uses substring method to print a string made up of the first n letters of s1 and the last n letters of s2.
Explanation:
The errors were:
1.
Scanner scan = Scanner(System.in);
Here new keyword is missing to create object scan of Scanner class.
Corrected statement:
Scanner scan = new Scanner(System.in);
2.
String s1 = nextLine();
Here object scan is missing to call nextLine() method of class Scanner
Corrected statement:
String s1 = scan.nextLine();
3.
String s2 = Scanner.nextLine();
Here class is used instead of its object scan to access the method nextLine
Corrected statement:
String s2 = scan.nextLine();
4.
String n = scan.nextLine();
Here n is of type String but n is a whole number so it should be of type int. Also the method nextInt will be used to scan and accept an integer value
Corrected statement:
int n = scan.nextInt();
5.
System.out.println(s1.substring(1,n-1) + s2.substring(s1.length()-n));
This statement is also not correct
Corrected statement:
System.out.println(s1.substring(0,n) + s2.substring(s2.length() - n ));
This works as follows:
s1.substring(0,n) uses substring method to return a new string that is a substring of this s1. The substring begins at the 0th index of s1 and extends to the character at index n.
s2.substring(s2.length() - n ) uses substring method to return a new string that is a substring of this s2. The substring then uses length() method to get the length of s2 and subtracts integer n from it and thus returns the last n characters of s2.

Write a function that takes a string and return the back half of the string. If the string has an odd number of characters, include the extra character. Your solution should also work if given and empty string. Examples: back_half('abba') should return 'ba' back_half('abcba') should return 'cba'
Answer:
Written in Python
def back_half(inputstring):
outputstring = ""
lent = len(inputstring)
if lent == 0:
outputstring ="Empty String"
elif lent%2 == 0:
begin = lent/2
for i in range(int(begin),lent):
outputstring = outputstring + inputstring[i]
else:
begin = (lent+1)/2
for i in range(int(begin-1),lent):
outputstring = outputstring + inputstring[i]
return outputstring
Explanation:
This line defines the function
def back_half(inputstring):
This line initializes outputstring to an empty string
outputstring = ""
This calculates the length of the input string
lent = len(inputstring)
This checks if the length of inputstring is 0. If yes, the function returns empty string
if lent == 0:
outputstring ="Empty String"
This checks if the length of inputstring is even.
elif lent%2 == 0:
begin = lent/2 This line gets the beginning of the half string
for i in range(int(begin),lent):
outputstring = outputstring + inputstring[i] This generates the half string
else: This checks for odd length
begin = (lent+1)/2 This line gets the beginning of the half string
for i in range(int(begin-1),lent):
outputstring = outputstring + inputstring[i] This generates the half string
return outputstring This returns the outputstring

The following equations estimate the calories burned when exercising (source): Men: Calories = ( (Age x 0.2017) — (Weight x 0.09036) + (Heart Rate x 0.6309) — 55.0969 ) x Time / 4.184 Women: Calories = ( (Age x 0.074) — (Weight x 0.05741) + (Heart Rate x 0.4472) — 20.4022 ) x Time / 4.184 Write a program with inputs age (years), weight (pounds), heart rate (beats per minute), and time (minutes), respectively. Output calories burned for men and women. Ex: If the input is 49 155 148 60, the output is:
In python:
age = float(input("How old are you? "))
weight = float(input("How much do you weigh? "))
heart_rate = float(input("What's your heart rate? "))
time = float(input("What's the time? "))
print("The calories burned for men is {}, and the calories burned for women is {}.".format(
((age * 0.2017) - (weight * 0.09036) + (heart_rate * 0.6309) - 55.0969) * (time / 4.184),
((age * 0.074) - (weight * 0.05741) + (heart_rate * 0.4472) - 20.4022) * (time / 4.184)))
This is the program.
When you enter 49 155 148 60, the output is:
The calories burned for men is 489.77724665391963, and the calories burned for women is 580.939531548757.
Round to whatever you desire.
The programming language is not stated. So, I will answer this question using Python programming language.
The program requires a sequence control structure, because it does not make use of conditions and iterations.
The program in python is as follows, where comments (in italics) are used to explain each line.
#This gets input for age, in years
age = int(input("Age (years): "))
#This gets input for weight, in pounds
weight = int(input("Weight (pounds): "))
#This gets input for heart rate, in beats per minutes
heart_rate = int(input("Heart Rate (beats per minutes): "))
#This gets input for time, in minutes
time = int(input("Time (Minutes) : "))
#This calculates the calories burnt for men
Men = ((age * 0.2017) - (weight * 0.09036) + (heart_rate * 0.6309) - 55.0969) * time / 4.184
#This calculates the calories burnt for women
Women = ((age * 0.074) - (weight * 0.05741) + (heart_rate * 0.4472) - 20.4022 ) * time / 4.184
#This prints the calories burnt for men
print("Men:", Men)
#This prints the calories burnt for women
print("Women:", Women)
At the end of the program, the program outputs the amount of calories burnt for men and women.
