Question

Create a function called totalCoins that takes an integer price of a product (in pennies) and an integer amount of money paid (in pennies). It should return via output parameters the number of dollars, quarters, dimes, nickels, and pennies given as change. Must use pointers. C programming

Answer 1

C Code:

#include<stdio.h>

//definition for totalCoins()
void totalCoins(int price, int amount)
{
    //variables declaration
    int change , dollors , quarters , dimes , nickels , pennies;

    //change is the amount to be returned as change
    change = amount - price;

    dollors=change/100; //calculating dollors from change
    //if dollor is valid or more than 0 than update remaining change value
    if(dollors>=1)
        change=change-dollors*100;

    quarters=change/25;  //calculating quarters from change
    //if quarters is valid or more than 0 than update remaining change value
    if(quarters>=1)
        change=change-quarters*25;

    dimes=change/10;  //calculating dimes from change
    //if dimes is valid or more than 0 than update remaining change value
    if(dimes>=1)
        change=change-dimes*10;

    nickels=change/5;  //calculating nickels from change
    //if nickels is valid or more than 0 than update remaining change value
    if(nickels>=1)
        change=change-nickels*5;

    //printing output...
    printf("\nChange=>\nDollors: %d\nQuarters: %d\nDimes: %d\nnickels: %d\nPennies: %d",dollors,quarters,dimes,nickels,change);



}

//main
int main()
{
    //variable declaration
    int price , amount;
    //taking inputs
    printf("Enter price and amount: ");
    scanf("%d%d",&price,&amount);
    //function call
    totalCoins(price ,amount);

    return 0;
}

Output:
