Use a switch statement after displaying the menu of choices.

Input Validation: If the user selects an item that is not on the menu, display an error message and loop again to display the menu.(Assume the user enters a single character, use thedefaultconstructor of the switch statement to check for an input error.)

Addition: Choose 2 random numbers. Top number between2 and 500.Bottom number less than top number and between1 and 99.(HINT: Generate num1 and num2, then use a while loop to check that num2 is less than num1. If it's not, then generate a new num2 and keep looping until you find a num2 that fits both criteria: less than the top number and between 1 and 99.)

Subtraction: Choose 2 random numbers. The top number is between2 and 500.The bottom number is between1 and 500and less than the top.

(HINT: use the same technique as above, a while loop to validate that num2 is less than num1)

Multiplication: Choose 2 random numbers between 1 and 12. (Easy, peasy. No while loop needed here.)

Division: Ensure there is no remainder. Number 1 should be between10 and 999.Number 2 is between1 and 9.(HINT: Use a while loop to validate that there is no remainder. The modulus operator is very useful here.)
