Q: (C++only) Write a program that will track how many medications are on hand at a small clinic. The program uses a structure to keep the medication name and quantity on hand. Your program should offer the user a menu with these choices: (1) Print the medication status; (2) Add pills to the on-hand count; (3) Remove or withdraw pills from the on-hand count; and (4) quit.

There are five functions in this program that are required: (1) main menu (2) populate pills (auto-populates the pill structure with names and pill counts with random numbers) (3) print status (prints the current on-hand counts) (4) add pills to the count (5) remove pills from the count

Perform input validation such that when the user selects to remove pills, they're first told how many pills are available. The validation should prevent them from entering a negative number or entering a number that's greater than the stock on hand.

Design your program in a loop, offering the main menu each time through the loop until the user elects to quit.

Your output should very closely resemble the output below:

here is example code here.
