/*        Write a high-security program in C that takes two numbers from STDIN and prints out their sum.         Input:            35            100        Output:            135    */

Write a C++ program that prompts the user to enter five test scores (decimal) then:• Prints the average of the scores.• Converts the average to an integer value. (Use a constant to store the number of scores).

Consider the following common task done repeatedly:• Read the next input (x = read())• If the input is not valid (valid(x)), exit the loop• Print the input read (print(x))• Repeat the loopUsing C++ syntax:Write the loop above using a pretest loop, posttest loop and a user-located loop control mechanism. From the three which one is more readable and why?
