Write a program in C++ that take three scores from user and calculate the average using do-while loop. It repeats as many times as the user wishes. The program only terminates when a user press N and Y to continue again any other character should display invalid character.

This program in C++ obtains a series of letter grades as input from a user. The program should calculate and output the total grade points and the grade point average (note: you may have to track the total number of inputs and the grade points to calculate the grade point average). The algorithm should execute 3 times for testing purposes.Use the appropriate loop for the main structure of the program that will stop accepting letter grades when the user inputs X. Also, choose the appropriate selection statement to convert the letter grade to the correct grade points.Additional Requirements:• Use appropriate data types and variable names throughout the code.• Use constants appropriately. Output needs to look like the image below.

Write a C program that does the following tasks using while loop: • Reads 7 integers. • Finds the sum of numbers that are divisible only by 5.
