You have a variable 'n' in main() that you set to the number of students via operator input (cin). You have another variable 'n' in your AverageGrade function that has the same name but it is not the same variable and you do not initialize it in any way. It's value is undefined. Perhaps what you want to do is make 'n' or 'number_of_students' and argument that is passed in to the AverageGrade function. Also it's type should be int not float. You have a 'for' loop in AverageGrade that is intended to calculate the sum of the scores for all students and you are keeping this sum in AveSco. Just to make thinks clearer, create a new float parameter called sum_of_all_scores and use it in your 'for' loop after initializing it to zero. During each pass thru your 'for' loop you need to increment sum_of_all_scores by the current students score. After you are done with the loop calculate the average score using the sum and the number of students. ------------------------------------ To unsubscribe, send a blank message to <mailto:[EMAIL PROTECTED]>.Yahoo!
