SUMMARY

The discussion focuses on efficiently distributing change using five and one dollar bills in C++. The correct method to calculate the number of one dollar bills is to use the modulus operator. Specifically, the statement numOnes = amountToChange % 5; accurately assigns the number of one dollar bills based on the remaining amount after distributing five dollar bills. This approach ensures that the maximum number of five dollar bills is used first, followed by the appropriate count of one dollar bills.

PREREQUISITES
  • Basic understanding of C++ programming
  • Familiarity with arithmetic operators in programming
  • Knowledge of input/output operations in C++
  • Understanding of the modulus operator (%) and its applications
NEXT STEPS
  • Explore C++ input/output streams for better user interaction
  • Learn about error handling in C++ to manage invalid inputs
  • Investigate the use of functions to modularize code for change distribution
  • Study algorithms for optimizing cash distribution in various scenarios
USEFUL FOR

Programmers, especially those learning C++, and anyone interested in algorithms for financial transactions or cash handling systems.

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 dollar bills to variable numOnes, given amountToChange. Hint: Use the % operator.

#include <iostream>
using namespace std;

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

cin >> amountToChange;
numFives = amountToChange / 5;

/ Your Input Goes Here/

count << "numFives: " << numFives << endl;
count << "numOnes: " << numOnes << endl;

return 0;
}

my input was amountToChange = numOnes % 5;

Which is incorrect.
