error LNK2019: unresolved external symbol "void __cdecl battingAverage(int (* const)[3],double (* const)[3],int,int)" (?battingAverage@@YAXQAY02HQAY02NHH@Z) referenced in function _main

It obviously has to deal with function battingAverage calling in main function, I have searched for this error here, tried to change c++ compiler options to 'Console' but it didn't help. Please help guys, I am sure it is a small issue but I am tired trying to fix it.

The battingAverage() function you wrote does not match the one you declared. — Hans Passant, Dec 06 '12 at 21:33

Your declaration:

void battingAverage(int[][numscores],double[][numscores],int,int);

Your definition:

void battingAverage(int bats[][numscores],double [],int numplayers,int  numscores)

As you can see, there's a discrepancy on the second argument - double[][numscores] vs double[]. So you're actually defining a whole different function.

Thank you guys, you are awesome, i dont know why i didnt notice it – user1743703 Dec 06 '12 at 21:35
I still cant get it to work. Do you guys see any errors? – user1743703 Dec 06 '12 at 22:15
@user1743703 meaning you get the same error? – Luchian Grigore Dec 06 '12 at 22:15
i got totally confused. honestly, this is not my code and it was my mistake, i wanted to do it fast and now i'm just looking at it and don't see any errors whatsoever – user1743703 Dec 06 '12 at 22:17
@user1743703 so you're not getting any errors. ok. what's the problem? – Luchian Grigore Dec 06 '12 at 22:19
i do get errors, i just don't know what to change in declaration or definition, and also the total function doesn't work properly – user1743703 Dec 06 '12 at 22:21
