Why does the for loop repeat in this recursion? (lemm.ee)

I used the debugger to examine this code but not understanding a couple areas.

  1. Why does the for loop repeat after it exits to print a new line? If it exits the loop, shouldn't it be done with it?
  2. Why is n incremented and not i as stated with i++?

int main(void)
{
    int height = get_int("Height: ");

    draw(height);
}

void draw(int n)
{
    if (n <= 0)
    {
        return;
    }

    draw(n - 1);

    for (int i = 0; i < n; i++)
    {
        printf("#");
    }
    printf("\n");
}

An example using a nested loop

$n = 3;

for ($i = 0; $i <= $n; $i++) {
    for ($j = 0; $j < $i; $j++) {
        echo '#';
    }
    echo "\n";
}
