Write a C++ program which tracks assignment grades. It should do the following:

Ask the user how many assignments there are.

Input a grade for each assignment from the user.

Print out the total points scored, and the average (mean) score.

If you have time, add these extra features:

print out the letter grade for the average score using the standard grading formula (90 or higher is an A, 80 or higher is a B, etc.)

Make sure each grade is at least 0 and at most 100
