Determine the result. Type "Error" if appropriate. Only literals appear in these expressions to focus attention on the operators; most practical expressions include variables. 100.0 % 40

Error

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 1 dollars bills to variable numOnes, given amountToChange. Hint: Use the % operator. #include <iostream> using namespace std; int main() { int amountToChange; int numFives; int numOnes; amountToChange = 19; numFives = amountToChange / 5; Put the answer here. cout << "numFives: " << numFives << endl; cout << "numOnes: " << numOnes << endl; return 0; }

numOnes = amountToChange / 5;
