you have 32 posts, been a member for 12 months - you can form a better question than that?

i need to pass board to function validate what i need to do

Why would you want to pass it to validate ?
board is a public member of Cpiece, it is accessibe anyway.

i need to pass it as a pointer

Why ?
Kurt

i need to pass it so that i could read the info of the board if i dont pass it it is all null

Cponn is derived from Cpiece, so it has access to everything Cpiece declares publicly. you don't need to pass it. you can say this->board, or this->Cpiece::board or even just board. you don't need to pass it as a parameter.

im trying to make this but its not working

Code:

---

col= board[1][1]->getcolor;

---

Code:

---

char Cponn::getcolor(){        return col;
 }

---

try

Code:

---

col= board[1][1]->getcolor();

this is literally the most useless thing you can say.

how is it not working?

what errors does it produce, if any?

what have you tried to resolve it?
