Code Challenge 7 - Change Calculator

---

Introduction

When a cashier performs transactions at a register, they quickly learn how to give back change efficiently. You start with the largest coin denomination and work your way down until you have exact change. For example, if the cahsier needs to give back 55 cents, they would take out two quarters and one nickel. You could technically give back 55 pennies, 5 dimes and a nickel, or some other change combination, but it’s arguably less efficient.

This change calculator would help novice cashiers give back the correct change starting with the largest denomination to the smallest.

Skills to Practice

• Prompting a user for input
• Saving user input to variables
• Performing a calculation using the modulus operator
• Formatting output using variables
