    restricting code from printing

    i am trying to stop a piece of code from printing when there is something already in a cell of a grid

    Code:
    for(int d = 0; d <DEPTH; d++){
    			for(int r = 0; r<ROW; r++){
    				for(int c = 0; c< COL; c++)
    				{
    					if(!array[d][r][c].getMarked())
    					{
    						
    						array[currentDepth][currentRow][currentCol].mark(player);
    						return;
    					}
    					else
    						cout << "Space already occupied by a player choose another. " << endl;
    						
    						return;
    				}
    			}
    		}
    					
    		break;
    what i am trying to do is if the cell in the grid is marked by a character (player) i want it to just print the cout statement and not replace the character that is already in it. the getMarked() is a bool statement to see if there is a character in the cell. it simply returns the players symbol. the mark(player) marks the cell that you are in with the players character. what it does right now is prints the character even if there is wone already in there and does not display the cout message i am so close to gettin it i know it but i cant any help would be great.

    maybe like this?

    Code:
    if(array[d][r][c].getMarked() != true)

    He said it was bool. The thing I'm suspicious about is why you're using three different int variables in your subscripts when you're marking. Shouldn't you be marking the one you checked and returned false?

    it returns a bool marked

    Code:
    bool getMarked() {return marked;}
    Code:
    void Cell::mark(Player *player)
    {
    	marked = true;
    	this->player = player;
    }
    
    char Cell::draw () {
    	if(active) return ACTIVE;
    	if(marked) return player->getMark();
    	return ' ';
    }
    marked starts off as false

    Code:
    Cell::Cell()
    {
    	marked = false;
    	active = false;
    }

    u mean array[d][r][c].getMarked ? im not marking with that its just checking of the cell im in is marked by a player. i mark with array[currentDepth][currentRow][currentCol].mark(player)

    so after a little testing i found out that what i really did there was stop printing if a player has won although it dont work perfectly though so now i dont know how to stop it from printing if there is someone there

    Exactly, why are you checking one thing and then marking another?

    That's like saying the kitchen is clear, there for there must not be anyone in the dining room. From what it seems, the current variables are what you are trying to mark from the beginning, then why are you looping to check all the other spots? Just check that one spot.

    so it should be something like

    Code:
    if(!array[currentDepth][currentRow][currentCol].getMarked())
    or something along that order.

    EDIT:

    yup thats it, i just threw that in there and it worked perfect thx
