find first empty cell?

What i want to do is use a for-loop to find the first empty cell in a 2D array and put a value in it. However, my code applies the loop to all empty cells in the array. What am i doing wrong here?

Code:

---

for (int row = 0; row < GRIDSIZE; row++) {
                for (int col = 0; col < GRIDSIZE; col++) {
                    if (isEmpty(row, col) == false) {
                        printIt();
                    } else {
                        setCell(row, col, 1);

---

Any help would be appreciated.

Break out of the loop when you've found an empty cell (and set a value in it):

Code:

---

} else {
  setCell(row, col, 1);
  return; // or break;
}

---

it still sets the value of more than one empty square. any other ideas?
edit: i got it to work. thanks anyway

I guess you simple used a break to get out of the (innermost) loop; you need to break out of two loops.

kind regards,

yeah, that was the case. thank you, Jos.
