Use C++ Write a program that prints a menu of choices: L -> Find the lowest value in a file H -> Find the highest value in a file A -> Find the average value in a file Q -> Quit Choose: The program does input validation and asks the user to reenter as long as the user’s choice does not correspond to an item on the menu. Invalid choice. Re-enter: If the user selects any valid choice other than Quit, the program prompts the user to enter the file name, Enter input file name: then reads the content of the file and prints the value requested (highest value, lowest value or average value). Highest value is 0 Lowest value is 0 Average value is 0 If the file cannot be opened or is empty, the program should display the message: File empty or could not open file Then the program displays the menu again. If the user selects Quit, the program prints “Exiting” and terminates. Additional requirements – Make sure you meet all the requirements You are not allowed to use arrays You are…
