What am I doing wrong in this C++ program?

[Linker] error undefined reference to `meanCalc(int, int)'





#include %26lt;iostream%26gt;


#include %26lt;cmath%26gt;


#include %26lt;fstream%26gt;


using namespace std;





int meanCalc(int,int);








int main ()


{

}

}

int meanCalc(int,int);





doesn't jibe with:





int meanCalc (int (array)[25], int count)





first takes two ints as input, second takes array of ints and an int. you need to reconcile that. i would modify this int meanCalc(int,int); accordingly.
