What will the following code output? (For an infinite loop, type "IL")

1) int x = 5; int y = 18; while (y >= x) { cout << y << " "; y = y - x; }

2) int z = 0; char c = 'y'; while (c = 'y') { cout << z << " "; cin >> c; z = z + 1; }

3) int x = 10; while (x != 3) { cout << x << " "; x = x / 2; }

4) int x = 0; while (x <= 5) { cout << x << " "; }
