# Help on finding average of a for loop

I need some help with finding the average of this for loop. The assignment requires that it be in individual functions.

What problems are you encountering?

As an aside, I can already see that you have a buffer overrun. Remember that C/C++ arrays are zero based, but you are accessing your arrays with indices 1 to 3.

The problem I'm having isn't an error, but it's not averaging the numbers that the user inputs.

Well, ignoring for now that you have a buffer overrun in studentScore(), your function studentScore() is return 0, rather than the sum of the scores. So when you try to compute the average in average(), 0 divided by 4, results in an average of zero.

Assuming that you fix things such that you are computing the sum of the scores, you are only inputting 3 scores (twice) in studentScore(). Then later when you try to compute the average, you are dividing by 4.
