    Trouble with errors

    I keep coming up with 2 errors with my code. These are the errors

    ||In function 'double arrayLabAve(int, double*)':|
    |188|error: a function-definition is not allowed here before '{' token|
    |214|error: expected '}' at end of input|
    ||=== Build finished: 2 errors, 0 warnings ===|

    Here is my
    #include <iostream>
    using namespace std;
    	#define Max_Students 10
            int grades;
            int eScores;

        for(int student=0; student<count ; student++)
    	    TotalExamGrade = TotalExamGrade + ExamGrade[student];
    	    TotalLabGrade = TotalLabGrade + LabGrade[student];
    	    TotalPointScore = TotalPointScore + PointGrade[student];
          AvgExamGrade = (float)TotalExamGrade / count;
          AvgLabGrade = TotalLabGrade / count;
          AvgPointScore = TotalPointScore / count;
    			cout<<"\n\n Exam Average        : "<<AvgExamGrade;
    			cout<<"\n Lab Average Average : "<<AvgLabGrade;
    			cout<<"\n Point Score Average : "<<AvgPointScore;
    Any help would be great.

    You never close your LabAve function before starting the next one.

    (And is this really C#? Doesn't look it.)

    This is not C#, its C++. And, I think "Code readability 101" needs to be the first required class in every computer science program. Like tabstop said, your arrayLabAve function is left with no return command and no closing brace.
    The keyboard is the standard device used to cause computer errors!
