Write a program, using a void function, that takes as input an integer and outputs two times the number if it is even; otherwise it outputs five times the number.  Then, using a void function, write a program that takes as input two integer values, say n and m. The function returns the sum and average of all the numbers between n and m (inclusive).

Write a complete C++ program that helps the teacher to calculate the result of students in the test of Programming Technique. The program should perform the following tasks: Task 1: Write a function named getInput. a) This is a non-returning function. b) It takes the score of question 1, score of question 2, and score of question 3 as input parameters. c) The function should ask the user to enter the score (per 100) for each question. It sends all the values entered by the user in (c) back to the calling module through the use of reference parameters. d)
