Can you show us your code where the compiler is complaining about?

Sidra Feroze 1-Nov-12 14:28pm

void main(){
int menuchoice,i,j;
clrscr();
_setcursortype(_NOCURSOR);
do{
menuchoice=menu();
if(menuchoice==1 || menuchoice==4){
if(menuchoice==1){
for(i=0;i<10;i++){
for(j=0;j<10;j++){
R[i][j]=0;
}
}
}

menuchoice=menu();
Where is the definition for the menu() function?

The prototype is the signature definition of the function, like you see in header files. Something along the lines of:
bool menu(HWND hWnd, char* menuTitle);.
