- Write a program that uses while loops to perform the following steps.
- Prompt the user to input two integers: firstNum and secondNum (firstNum must be less than secondNum).
- Output all numbers between firstNum and secondNum
- Edit, compile and run the following program. This program provides a different solution using a switch statement.
