I'm creating a matrix containing a struct and I've came across some errors.
game_mat.cpp - displays the matrix in graphics.

setfillstyle(1,RED);

void q_game(char * name,records rec[N][N]);
The compiling errors:
1.
Parameter 'rec' is never used2.
Undefined symbol 'rec'I don't understand where i went wrong..
rec is defined and known in each file..
Any thoughts?..
