Passing 2d array to header

[majesticSam]

I'm having some trouble passing a 2d array from my .cpp file to a header file

My function in my .cpp file looks like
void Lab::logoff(int (&arr)[arrC][arrR])


and my pass to my class looks like this:

class Lab{
public
     int logoff(int (&arr)[3][5]) const;

}

And I'm getting the error:

/home/ubuntu/workspace/Lab.cpp:148:6: error: prototype for ‘void Lab::logoff(int (&)[3][5])’ does not match any in class ‘Lab’

   int logoff(int (&)[3][5]) const;   

Can someone please help me?

void Lab::logoff(int (&arr)[arrC][arrR])

int logoff(int (&)[3][5]) const;
