[Solved] CS151 Module 5

Design a class Numbers that can be used to translate whole dollar* amounts in the range of 0 through 9999 into an English description* of the number.** Algorithm:* 1. Accept input from user. Validate that number is between 0 and 9999* 2. Determine how many digits the number has* 3. Using the number of digits, select the most significant digit and* output it in English* 4. Remove the most significant digit to move place value lower* 5. Continue to determine the most significant digit, display it* in English, and lower the place value until the number is less than* 20*/
