I forgot to show d programme b4, check it now.

Your Code Look too Busy bro.
*Use Vectors and loops to Read in Multiple Courses, units and Grades
*i will Advice you to check Your Course input against a letter like "x" or "X", why ?, Because You cant compare a string with an Int. expect You want to go tru conversion process.

Thanks boss. I just did it. Actually it's an assignment, I had to think better and I created a do loop with internal if command. That did d magic.
