Modify the program again so it displays a menu allowing the user to select an addition, subtraction, multiplication, or division problem. The final selection on the menu should let the user quit the program. After the user has finished the math problem, the program should display the menu again. This process is repeated until the user chooses to quit the program.

Use a switch statement for the menu

Input Validation: If the user selects an item not on the menu, display an error message and display the menu again.

Addition: Choose 2 random numbers. Top number between 1 and 500. Bottom number less than top number and between 1 and 99.

Subtraction: Choose 2 random numbers between 1 and 500. The bottom number is less than top.

Multiplication: Choose 2 random numbers between 1 and 12.

Division: No remainder. Choose a single digit number for number 2. Number 1 should be a 3 digit multiple of number 2.
