Understanding of this if statement

I created a finished code for a mario problem set.

Want to know if I understand the last if statement correctly.

If the user enters 4, the code will print out 4 columns with hashes, because it uses the remaining rows to print a blank space on each column.

Just wanted to know, if my point of view is correct.

#include    <stdio.h>
#include    <stdlib.h>

int main(void)
{

    int r, c, ans;

    printf("Value between 0 and 9\n");
    scanf("%d", &ans);

    while(ans < 1 || ans > 8)
    {
        printf("INVALID REPSONSE PLEASE TRY AGAIN\n");
        scanf("%d", &ans);
    }

    if(ans > 0 || ans <= 8)
    {
        for(r = 0; r <= ans; r++)
        {
                for(c = 0; c < ans; c++)
                {
                    if(c >= ans - r)
                    {
                        printf("#");
                    }else
                        {
                            printf(" ");
                        }
                }
            printf("\n");
        }
    }
    return 0;
}
