Thread: Trying to figure out how the coin denominations are computed.

Code:

// Import libraries
#include <stdio.h>
#include <math.h>
#include <cs50.h>

int main()
{
    // Define an int type variable
    int coins_due;
    // Create a 'do while' loop
    do
    {
        float change_owed = get_float("Change owed: ");
        coins_due = round(change_owed * 100);
    }
    while (coins_due <= 0);

    int quarters = coins_due / 25;
    int dimes = (coins_due % 25) / 10;
    int nickels = ((coins_due % 25) % 10) / 5;
    int pennies = ((coins_due % 25) % 10) % 5;

    // Print output
    printf("Coins due: %d\n", quarters + dimes + nickels + pennies);
}
