Question

A program that will calculate a student’s grade average for a class and then store the result in an array to be able to print out the averages of the class. First you will need to calculate the test average and then the lab average. The user will then enter the midterm grade and final exam grades. The formula to find the semester average is 40% of lab average + 42% of test average +9% of midterm + 9% of final. The semester average is stored in an array of unknown size (for different classes) and then printed out. Here is a sample data sheet below but you may use any data you choose.
