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 required to implement and use the following functions. These functions take as parameters a string (file name) passed by value, and a double passed by reference. Each function returns a bool which is true if the file open is successful and if the file is not empty, false otherwise. If the file open is successful and the file is not empty, the function passes back the appropriate value from all values in the file through the reference variable. If the file open failed, or the file is empty, the function does not pass back a value in the reference variable. bool averageFromFile(string filename, double& value) bool lowestFromFile(string filename, double& value) bool highestFromFile(string filename, double& value)

You are not allowed to use arrays
You are required to implement and use the following functions. These functions take as parameters a string (file name) passed by value, and a double passed by reference. Each function returns a bool which is true if the file open is successful and if the file is not empty, false otherwise. If the file open is successful and the file is not empty, the function passes back the appropriate value from all values in the file through the reference variable. If the file open failed, or the file is empty, the function does not pass back a value in the reference variable.
