Thread: Pointer to class?

you can either use pointers:

Code:

Lf::Lf(int x, int y, Grid* mygrid)
{
   mygrid->addGridEntity(x, y, 'o'); // use arrow not dot when dealing with a pointer
}

int main()
{
   Grid mygrid;
   Lf mylf(3, 3, &mygrid);
   mygrid.printGrid();
}

or references

Code:

Lf::Lf(int x, int y, Grid& mygrid)
{
   mygrid.addGridEntity(x, y, 'o'); // use dot with a reference
}

int main()
{
   Grid mygrid;
   Lf mylf(3, 3, mygrid); // address is taken implicitly with reference initialization
   mygrid.printGrid();
}
