Question

Construct a program in C++ that exchanges coins for cash like Coinstar that is located in several grocery stores. You will prompt the user to provide you with the total number of pennies, nickels, dimes, and quarters, respectively.   You are to determine the total amount of money entered by the user and then output the cash that should be received. For example, if a user enters 50 pennies, 10 dimes, 10 nickels, and 5 quarters, then the user would receive 3 dollars and 1 quarter. Your program output should be as follows:

Your program should have the following format on the output screen:

“Welcome to (your name) Coin Exchanger:

“Please enter the number of pennies:”

>> 50

“Please enter the number of nickels:”

>> 10

“Please enter the number of dimes:”

>>10

“Please enter the number of quarters:”

>>5

The total amount of money due: (Note: Program must output the values from calculating the money)

“The number of dollars:”     3

“The number of quarters:” 1

“The number of dimes:”       0

“The number of nickels:”     0

   “The number of pennies:”   0

Answer 1

Here is the code for your problem.

#include <bits/stdc++.h>

using namespace std;

int main()

{

    int pennies, nickels, dimes, quarters;

    // reading input from user

    cout << "Welcome to (your name) Coin Exchanger:" << endl;

    cout << "Please enter the number of pennies:\t";

    cin >> pennies;

    cout << "Please enter the number of nickels:\t";

    cin >> nickels;

    cout << "Please enter the number of dimes:\t";

    cin >> dimes;

    cout << "Please enter the number of quarters:\t";

    cin >> quarters;

    // calculating total

    double total = 1.0 * (pennies + nickels * 5 + dimes * 10 + quarters * 25) / 100.0;

    // calculating eery value from total and printing

    int dollars = floor(total);

    cout << "The number of dollars:\t" << dollars << endl;

    total -= dollars;

    total *= 100;

    quarters = floor(total / 25);

    cout << "The number of quarters:\t" << quarters << endl;

    total -= (quarters * 25);

    dimes = floor(total / 10);

    cout << "The number of dimes:\t" << dimes << endl;

    total -= (dimes * 10);

    nickels = floor(total / 5);

    cout << "The number of nickels:\t" << nickels << endl;

    total -= (nickels * 5);

    cout << "The number of pennies:\t" << total << endl;

    return 0;

}
