GRADE ARRAY_NEED ADVICE FAST
Hello. I am absolutely brandnew in c++. I am currently in the middle of my Computer Engineering class (mainly for the electronics part) but nevertheless I have to study a bit of coding. I have a project I've been working on for class. I was wondering if any of you could point me in the right direction. I know I DEFINITELY have issues with calling functions, no doubt. I appreciate your help!
// Week 6 Lab

// The following framework support the basic assignment requirements

// The framework needs to be updated to include all of the
// necessary processing and to address all of the requirements

Read these, try to finish it, and if you still have problems, go ahead and post the errors/code.

Oh, and you need

Oh, and you need

Here are the error codes. They are more than I remembered but I think the initial way I had it was wrong anyways. I will re-read those chapters on the tutorials page. I know my issues are with the function structure and how i'm calling them. I appreciate your help!

okay
I have fixed quite a bit and now the error code i'm getting is...
error C2664: 'getExamScores' : cannot convert parameter 1 from 'int (__cdecl *)(void)' to 'int'
int getExamScores(int, double[]);- this is my definition declaration before main()
int getExamScores(int numStudents, double arrayExamAve[])- this is the function itself
getExamScores(getStudentCount,arrayExamAve);this is the function being called (line 57)
thanks

getExamScores(getStudentCount(),arrayExamAve);or better
getExamScores(numStudents,arrayExamAve);getStudentCount is a function. In your case you don't want to pass this in getExamScores. What you want to pass is the number of students. So, first call
numStudents=getStudentCount();and then
getExamScores(numStudents,arrayExamAve);and when you post your code use code tags like this:
[c o d e]...your code here...[/ c o d e]
(without the spaces between the characters in "c o d e" and "/ c o d e")
