I overlooked one step in the assignment however.
I need to ask the user for input about how many homework, project, and exam they have completed and then set the array equal to that. I wrote the code based on the number of assignments in class and do not know how to change it to make it work by input. Could someone point me in the right direction please?

input = GetValidInput(promptString);
