C++ program to convert quarter, dime and nickel to cent

The following C++ program converts quarters, dimes and nickels to cents. It is assumed that you know the basic syntax of a C++ program.

In this article, you’ll learn:

1. To convert quarters to cents in C++.
2. To convert dimes to cents in C++.
3. To convert nickel to cents in C++.
4. Finally, to convert quarters, dimes and nickels to cents in C++.

We’ll use the step by step approach to understand the problem. To understand how to write a program to convert this into that in programming, you must know the relation between the quantities or the units.

Prerequisite knowledge to understand the program

• 25 cents make one quarter, i.e., 1 quarter = 25 cents.
• 10 cents make one dime, i.e., 1 dime = 10 cents.
• 5 cents make one nickel, i.e., 1 nickel = 5 cents.

Now, using this information, try to calculate how many cents are there in 3 quarters. Got the answer? Yes, 75 cents will be the answer. We got it using basic mathematics. 3 * 25 = 75 cents.

We’ll use this information and the basic syntax of a C++ program to convert quarter, dime and nickel to cents.

Step 1: Basic syntax of a C++ program

#include <iostream>
using namespace std;

int main()
{
      /* Statements here */
      return 0;
}

Step 2: Creating variables to store values and taking input from the user

#include <iostream>
using namespace std;

int main()
{
    int quarter, dime, nickel, cent;
    
    cout << "Enter the number of quarter, dime and nickel respectively: ";
    cin >> quarter>>dime>>nickel; //input from the user
    return 0;
}

Step 2: Using the relations mentioned above to calculate number of cents

#include <iostream>
using namespace std;

int main()
{
    int quarter, dime, nickel, cent;
    
    cout << "Enter the number of quarter, dime and nickel respectively: ";
    cin >> quarter>>dime>>nickel;
    cent = quarter*25 + dime*10 + nickel*5; //basic mathematics

    return 0;
}

Step 3: Printing the calculated result(Complete program)

#include <iostream>
using namespace std;

int main()
{
    int quarter, dime, nickel, cent;
    
    cout << "Enter the number of quarter, dime and nickel respectively: ";
    cin >> quarter>>dime>>nickel;
    cent = quarter*25 + dime*10 + nickel*5;     // this will store the result into cent variable

    //to print the calculated value
    cout << "If there are " << quarter << " quarters " << dime << " dimes, \nand "<< nickel << " nickels, then the equivalent to cent is " << cent;     
    cout<<"\n\n End of the Program";
    return 0;
}

That’s it. So this is how to create a C++ program that converts quarters, dimes, and nickels into cents.

Sample output:

Now before looking at the output, try to calculate the number of cents in 3 quarters, 4 dimes and 5 nickels manually on a paper or calculator.

It goes like, 3 quarters = 3 * 25 = 75 cents, 4 dimes = 4 * 10 = 40 dimes, and 5 nickels = 5 * 5 = 25 cents. That means a total of 75 + 40 + 25 = 140 cents. Now have a look at the sample output below to see if our program works fine.

That’s great. We did it. Now try to write C++ program that converts quarters into cents and let me know in the comments below.

What did we learn?

• C++ program to convert quarter, dime and nickel into cents.
• How to approach the solution of a C++ program step by step as a beginner.
