This is a pretty simple program, but I am still having problems, and my CompSci teacher has been out for a couple of weeks.
Code:
/* Lenavich III
Period 6
This program computes the average, G.P.A., and letter grades of 20
different students, as well as outputting that in a table when given
the names of the 20 different students and a number of their grades.
