Programming

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");
}
