WRITE IT IN C++ LANGUAGE

Your program is to present the user with a menu that offers the following options:

1. Set principal

2. Set annual interest

3. Set number of years

4. Amortization schedule

5. Exit

The menu should be redisplayed after each menu option 1-4 is successfully executed.

Along with the menu options, the current values for principal, annual interest, and number of years should be displayed. The monthly payment amount should also be displayed IF the annual interest rate and number of years are non-zero. If either are zero, a value for the monthly payment should not be displayed. Run the sample executable for this assignment to see the expected behavior.

If the user selects any one of the set options (#1-#3) from the menu, they should be prompted for a new value that takes the place of the current value.
