Assigning numOnes with Modulo Operator

[ineedhelpnow]

A cashier distributes change using the maximum number of five dollar bills, followed by one dollar bills. For example, 19 yields 3 fives and 4 ones. Write a single statement that assigns the number of distributed 1 dollar bills to variable numOnes, given amountToChange. Hint: Use %.

Sample program:

#include <iostream>
using namespace std;

int main() {
int amountToChange = 0;
int numFives = 0;
int numOnes = 0;

amountToChange = 19;
numFives = amountToChange / 5;
<STUDENT CODE>

return 0;
}

i only have to write code for the part that says <student code>. i tried numOnes = 19 % 5;

its wrong though. it passed two tests but failed one.

oh i got it. it was supposed to be amountToChange % 5 not 19 % 5 because then it only works for one value

To which variable are you applying the modulus operator?

Good! (Yes)

That was my suspicion, that you were applying "% 5" to the wrong value. :D

The correct statement to assign the number of distributed one dollar bills to the variable numOnes would be: numOnes = amountToChange % 5; This uses the modulo operator (%) to find the remainder when dividing the amountToChange by 5, which represents the number of one dollar bills needed after distributing the maximum number of five dollar bills.
