use

PHP Code:

void** Matrix; 


void can mean anything so you may use

PHP Code:

void screen::setSeat(int xSeat, int ySeat, customer *cust)
{
  seatsXY[xSeat][ySeat] = (void*)cust;
} 


Or if you're 100% shure + it's called a lot + you want speed increase without "type" checking

PHP Code:

void screen::setSeat(int xSeat, int ySeat, customer *cust)
{
  seatsXY[xSeat][ySeat] = static_cast<void *>(cust);
}
