Question

In the U.S coin system, the penny is the basic coin, and it is equal to cent, a nickel is equivalent to 5 cents, a dime is equivalent to 10 cents, a quarter is equivalent to 25 cents, and half-dollar is equivalent to 50 cents. Design and implement a program that would make use of the functions shown below. Each function has a single int formal parameter Amount.
a) HalfDollars (): Compute the maximum number of half-dollars that could be used in making change for Amount.
b) Quarters():Compute the maximum number of quarter that could be used in making change for Amount
c) Dimes ():Compute the maximum number of dimes that could be used in making change for Amount
d) Nickels () : Compute the maximum number of nickels that could be used in making change for Amount

Answer 1

I'm assuming the argument "Amount" is in cents. Here is the code

# include <iostream>
using namespace std;

//the amount of coins that can be made in change
//is the quotient when the amount is divided
//by the coin value
//a / b in C++ computes exactly this

//if Amount is in dollars, not cents
//then simply multiply the Amount by 100
//before doing the division

int HalfDollars(int Amount) {
return Amount / 50;
}

int Quarters(int Amount) {
return Amount / 25;
}

int Dimes(int Amount) {
return Amount / 10;
}

int Nickels(int Amount) {
return Amount / 5;
}

int main() {
int n;
cout << "Enter Amount: ";
cin >> n;

cout << "Number of half-dollars " << HalfDollars(n) << endl;
cout << "Number of quarters " << Quarters(n) << endl;
cout << "Number of dimes " << Dimes(n) << endl;
cout << "Number of nickels " << Nickels(n) << endl;

return 0;
}
