Programming technique exercise Question 1). 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: • Write a function named getinput. This is a non-returning function. It takes the score of question 1, score of question 2, and score of question 3 as input parameters. the function should ask the user to enter the score (per 100) for each question.
