Not sure if this is beginner, but...

I am making a sudoku type game and its a console app, so I am coding the arrows to move the cursor. The cursor is going to be simply changing the color of the target location, but I am printing the entire board at once.

Like this:
1
2
3
4
 
int GameBoard[9][9];
//Here is the code that handles arrow key pressing
//and the code that handles moving the cursor.
cout<<GameBoard;


Any suggestions so that I don't have to write 81 if statements to cover every possibility?

Thanks.

Why do you want to write 81 if-statements. You know the start position of your cursor and you know the "range of your board" (0 to 8 on x-axis and 0 to 8 on y-axis). If you hit a arrow button you can calculate the new postion of the cursor.

e.g.:
<-- eq. -1 on x-axis; --> eq. +1 on x-axis

So you must only watch out that you don't leave your board. Do you understand?

Right, but I want to have every number white except the one where my cursor is, which I want yellow. I know how to change text color, but I don't know how to change one part, say GameBoard[6][3] to yellow without changing the whole thing. I mean, I could write the 81 if statements and have it output different each time, but I don't want to have to do that.

        case 8:

        break;
        case 9:
            if(ConstSquare[X][Y]){
                Square[X][Y]=9;
        }
        break;
    }
}


Hope it helps. The display would be harder...

No, but you can find all the win32 API codes for them here:
