Pushes and pulls are the computer operations which enable the user to perform numerical tasks. The input commands are interpreted by the computer software and these tasks are converted into numeric values to generate output.
In this assignment, you will implement an online banking system. Users can sign-up with the system, log in to the system, change their password, and delete their account. They can also update their bank account balance and transfer money to another user’s bank account.
You’ll implement functions related to File I/O and dictionaries. The first two functions require you to import files and create dictionaries. User information will be imported from the "users.txt" file and account information will be imported from the "bank.txt" file. Take a look at the content in the different files. The remaining functions require you to use or modify the two dictionaries created from the files.
Each function has been defined for you, but without the code. See the docstring in each function for instructions on what the function is supposed to do and how to write the code. It should be clear enough. In some cases, we have provided hints to help you get started.
def import_and_create_dictionary(filename):
'''
This function is used to create a bank dictionary. The given argument is the filename to load.
Every line in the file will look like
key: value
Key is a user's name and value is an amount to update the user's bank account with. The value should be a
number, however, it is possible that there is no value or that the value is an invalid number.
What you will do:
- Try to make a dictionary from the contents of the file.
- If the key doesn't exist, create a new key:value pair.
- If the key does exist, increment its value with the amount.
- You should also handle cases when the value is invalid. If so, ignore that line and don't update the dictionary.
- Finally, return the dictionary.
Note: All of the users in the bank file are in the user account file.

Explanation:
The python program is a banking application system that creates a list of user accounts and their login details from the bank.txt and user.txt file. The program also uses the information to log in and check for users already logged into their account with the "loggedin" global variable.
In this exercise we have to use the knowledge of programming in the python language, in this way we find that the code can be written as:
The code can be seen in the attached image.
To make it even simpler to visualize the code, we can rewrite it below as:
def import_and_create_dictionary(filename):
bank = {}
i = 1
with open(filename, "r") as file:
for line in file:
(name, amt) = line.rstrip('\n').split(":")
bank[i] = [name.strip(), amt]
i += 1

You want to make access to files easier for your users. Currently, files are stored on several NTFS volumes such as the C:, D:, and E: drives. You want users to be able to access all files by specifying only the C: drive so they don't have to remember which drive letter to use. For example, if the accounting files are stored on the D: drive, users should be able to access them using C:\accounting. What can you do?
Answer:
volume mount points
Explanation:
The best thing to do would be to use volume mount points. This is a feature that allows you to mount/target (from a single partition) another folder or storage disk that is connected to the system. This will easily allow the user in this scenario to access the different files located in the D: and E: drive from the C:\ drive itself. Without having to go and find each file in their own separate physical drive on the computer.
Why is sequencing important?

As you will solve more complex problems, you will find that searching for values in arrays becomes a crucial operation. In this part of the lab, you will input an array from the user, along with a value to search for. Your job is to write a C++ program that will look for the value, using the linear (sequential) search algorithm. In addition, you should show how many steps it took to find (or not find) the value, and indicate whether this was a best or worst case scenario (... remember the lecture). You may refer to the pseudo-code in the lecture, but remember that the details of the output and error conditions are not specified there. Also, note that in pseudo-code arrays are sometimes defined with indices 1 to N, whereas in C++ the indexes span from 0 to N-1.
The program will work as follows. First, you should ask the user to enter the size of the array, by outputting:
"Enter the size of the array: "
to the console. If the user enters an incorrect size, you should output the error message:
"ERROR: you entered an incorrect value for the array size!"
and exit the program. If the input is a valid size for the array, ask the user to enter the data, by outputting
"Enter the numbers in the array, separated by a space, and press enter: "
Let the user enter the numbers of the array and store them into a C++ array. Up to now, this should be exactly the same code as Lab#2. Next, ask the user a value v to search for in the array (called the "key"), by outputting:
"Enter a number to search for in the array: " to the screen, and read the key v.
Search for v by using the linear search algorithm. If your program finds the key, you should output:
"Found value v at index i, which took x checks. "
where i is the index of the array where v is found, and x is the number of search operations taken place.
If you doesn't find the key, then output: "
The value v was not found in the array!"
Then indicate whether you happened to run into a best or worst case scenario. In case you did, output: "
We ran into the best case scenario!" or "We ran into the worst case scenario!"
otherwise, don't output anything.
Answer:
#include<iostream>
using namespace std;
int main() {
cout<<"Enter The Size Of Array: ";
int size;
bool isBestCase=false;
cin>>size;
if(size<=0){
cout<<"Error: You entered an incorrect value of the array size!"<<endl;
return(0);
}
int array[size], key;
cout<<"Enter the numbers in the array, separated by a space, and press enter:";
// Taking Input In Array
for(int j=0;j<size;j++){
cin>>array[j];
}
//Your Entered Array Is
for(int a=0;a<size;a++){
cout<<"array[ "<<a<<" ] = ";
cout<<array[a]<<endl;
}
cout<<"Enter a number to search for in the array:";
cin>>key;
for(i=0;i<size;i++){
if(key==array[i]){
if(i==0){
isBestCase=true; // best case scenario when key found in 1st iteration
break;
}
}
}
if(i != size){
cout<<"Found value "<<key<<" at index "<<i<<", which took " <<++i<<" checks."<<endl;
} else{
cout<<"The value "<<key<<" was not found in array!"<<endl;
cout<<"We ran into the worst-case scenario!"; // worst-case scenario when key not found
}
if(isBestCase){
cout<<"We ran into the best case scenario!";
}
return 0;
}
Explanation:
The C++ source dynamically generates an array by prompting the user for the size of the array and fills the array with inputs from the user. A search term is used to determine the best and worst-case scenario of the created array and the index and search time is displayed.

For which of the following tasks would a for-each loop be appropriate?
A. Reversing the order of the elements in an array.
B. Printing all the elements at even indices of an array.
C. Printing every element in an array.
D. Determining how many elements in an array of doubles are positive.
E. Determining whether an array of Strings is arranged in alphabetical order.
F. Printing every even number in an array of ints.
Answer:
The answer is "Option B, C, and F".
Explanation:
In the For-each loop, it is used for traversing items in a sequence is the control flow expression. It typically required a loop becomes referred to it as an enhanced loop for iterating its array as well as the collection elements. This loop is a version shortcut that skips the need for the hasNext() method to get iterator and the loop and over an iterator, and the incorrect choice can be determined as follows:
In choice A, it is wrong because it can't reverse the array element.In choice D, it is wrong because it can't determine the array of positive.In choice E, it is wrong because it can't determine an array of the sting in alphabetical order.An analogue sensor has a bandwidth which extends from very low frequencies up to a maximum of 14.5 kHz. Using the Sampling Theorem, what is the minimum sampling rate (number of samples per second) required to convert the sensor signal into a digital representation?
If each sample is now quantised into 2048 levels, what will be the resulting transmitted bitrate in kbps?
Give your answer in scientific notation to 1 decimal place.
Hint: you firstly need to determine the number of bits per sample that produces 2048 quantisation levels
Answer:
3.2*10^5
Explanation:
By Nyquist's theorem we must have 2*14.5kHz=29kHz so 29,000 samples per second. 2048=2^11 so we have 11 bits per sample. Finally we have 29000*11 bits per second (bps) =319000=3.2 * 10^5
In this exercise we want to know how many bits will be transmitted between the two intelligences, so we have that:
[tex]3.2*10^5 bits[/tex]
What is the Nyquist's theorem?According to the theorem, the reconstructed signal will be equivalent to the original signal, respecting the condition that the original signal does not contain frequencies above or above this limit. This condition is called the Nyquist Criterion, or sometimes the Rahab Condition.
in this way we have:
[tex]2*14.5kHz=29kHz \\2048=2^11 =11 bits \\ 29000*11 =319000=3.2 * 10^5[/tex]

Concentrate strings
Write code that concatenates the character strings in str1 and str2, separated by a space, and assigns the result to a variable named joined. Assume that both string variables have been initialized.
Two Letters in Word
Given a character string stored in a variable called word, write code that concatenates the fifth character of the word to the third character from the end of the word, and assigns that string to a variable named two_letters. Assume that word already has a value and is at least five characters long.
Set the Number of Cards if Necessary
Write code that sets the value of the variable num_cards to seven if its current value is less than seven. Otherwise, don't change the value. Assume that nuncards already has an initial value.
Answer:
In Python:
(a) Concatenate strings:
joined = str1+" "+str2
(b) Two Letters in Word :
two_letters = word[4]+word[-3]
(c) Set Numbers in Card
if num_cards < 7:
num_cards = 7
Explanation:
The code segments were written in Python
All variables were assumed to have been initialized
Solving (a): Concatenate strings:
To do this, we make use of + operator.
So, the concatenation of str1 and str2 with space in between is
str1+" "+str2
When assigned to variable joined, it becomes
joined = str1+" "+str2
Solving (b): Two Letters in Word :
The character at the 5th position is represented with index 4 i.e. word[4]
To access a character from the end, we make use of - sign. So, the third character from the end is word[-3]
Concatenate them using + operator.
So, we have:
two_letters = word[4]+word[-3]
Solving (c): Set Numbers in Card
Here, we make use of the if condtion.
First, check if num_cards is less than 7(i.e. num_cards < 7)
If true, assign num_cards to 7
So, we have:
if num_cards < 7:
num_cards = 7

Suppose a program contains 500 million instructions to execute on a processor running on 2.2 GHz. Half of the instructions takes 3 clock cycles to execute, where rest of the instructions take 10 clock cycle. What is the execution time of the program
Answer:
1.48 s
Explanation:
Number of instructions = 500 million = 500 * 10⁶
clock rate = 1 / 2.2 GHz = 1 / (2.2 * 10⁹ Hz) = 0.4545 * 10⁻⁹ s
We need to compute the clocks per instruction (CPI)
The CPI = summation of (value * frequency)
CPI = (50% * 3 clock cycles) + (50% * 10 clock cycles)
CPI = (0.5 * 3) + (0.5 * 10) = 1.5 + 5 = 6.5
Execution time = number of instructions * CPI * clock rate
Execution time = 500 * 10⁶ * 6.5 * 0.4545 * 10⁻⁹ =1.48 s

The Boolean Foundation hosted a raffle to raise money for charity and used a computer program to notify the participants about the results. Unfortunately, the program they used was not very robust and all 250 participants received an email telling them that they won... and that their name is Shauna.
Improve this program by writing a function called sendEmail to print a personalized email to stdout. The function should take three parameters:
The name of the recipient
The prize for the raffle
Whether or not the recipient won
Use the email template from the existing program.
#include
using namespace std;
int main() {
cout << "Dear Shauna," << endl;
cout << "You are the winner of our raffle for charity." << endl;
cout << "The prize was: a stuffed giraffe toy" << endl;
cout << "Thank you for giving to charity!" << endl;
cout << "Sincerely," << endl;
cout << "The Boolean Foundation" << endl;
return 0;
}
Answer:
The function is as follows:
void sendEmail(string name, string prize, string win_lose){
cout << "Dear "<<name<<", " << endl;
cout << "You are the "<<win_lose<<" of our raffle for charity." << endl;
cout << "The prize was: "<<prize<< endl;
cout << "Thank you for giving to charity!" << endl;
cout << "Sincerely," << endl;
cout << "The Boolean Foundation" << endl;
}
Explanation:
This defines the function along the three parameters
void sendEmail(string name, string prize, string win_lose){
This prints the salutation with the person's name
cout << "Dear "<<name<<", " << endl;
This prints if the person won or lost
cout << "You are the "<<win_lose<<" of our raffle for charity." << endl;
This prints the prize, if any
cout << "The prize was: "<<prize<< endl;
The following is the closing remark
cout << "Thank you for giving to charity!" << endl;
cout << "Sincerely," << endl;
cout << "The Boolean Foundation" << endl;

Your first submission for the CIS 210 Course Project should include the following functionality: - Requests the user to input his/her first name - Formats the name to capitalize the first letter and makes all remaining characters lowercase, removing any spaces or special characters - Output the formatted name to the console
Answer:
In Java:
import java.util.*;
public class Main{
public static void main(String[] args) {
Scanner input = new Scanner(System.in);
String name;
System.out.print("First name: ");
name = input.next();
name= name.substring(0, 1).toUpperCase() + name.substring(1).toLowerCase();
System.out.print(name);
}
}
Explanation:
This declares name as string
String name;
This prompts the user for first name
System.out.print("First name: ");
This gets the name from the user
name = input.next();
This capitalizes the first letter of name and makes the other letters to be in lowercase
name= name.substring(0, 1).toUpperCase() + name.substring(1).toLowerCase();
This prints the formatted name
System.out.print(name);
The third assignment involves writing a Python program to compute the cost of carpeting a room. Your program should prompt the user for the width and length in feet of the room and the quality of carpet to be used. A choice between three grades of carpeting should be given. You should decide on the price per square foot of the three grades on carpet. Your program must include a function that accepts the length, width, and carpet quality as parameters and returns the cost of carpeting that room. After calling that function, your program should then output the carpeting cost.
Your program should include the pseudocode used for your design in the comments. Document the values you chose for the prices per square foot of the three grades of carpet in your comments as well.
You are to submit your Python program as a text file (.txt) file. In addition, you are also to submit a test plan in a Word document or a .pdf file. 15% of your grade will be based on whether the comments in your program include the pseudocode and define the values of your constants, 70% on whether your program executes correctly on all test cases and 15% on the completeness of your test report.
Answer:
# price of the carpet per square foot for each quality.
carpet_prices=[1,2,4]
def cal_cost(width,height,choice):
return width*height*carpet_prices[choice-1]
width=int(input("Enter Width : "))
height=int(input("Enter Height : "))
print("---Select Carpet Quality---")
print("1. Standard Quality")
print("2. Primium Quality")
print("3. Premium Plus Quality")
choice=int(input("Enter your choice : "))
print(f"Carpeting cost = {cal_cost(width,height,choice)}")
Explanation:
The cal_cost function is used to return the cost of carpeting. The function accepts three arguments, width, height, and the choice of carpet quality.
The program gets the values of the width, height and choice, calls the cal_cost function, and prints out the string format of the total carpeting cost.
