Program gives the correct answers.
But I getting WA1.
What is wrong?

#include <stdio.h>

int main ()
{
    int n, y, count;
    char x;

    for (scanf ("%d", &n); n > 0; --n)
    {
        fflush (stdin);
        scanf ("%c%1d", &x, &y);

        count = 0;

        if (x + 2 <= 'h' && y + 1 <= 8) ++count;
        if (x + 1 <= 'h' && y + 2 <= 8) ++count;
        if (x - 2 >= 'a' && y + 1 <= 8) ++count;
        if (x - 1 >= 'a' && y + 2 <= 8) ++count;
        if (x + 2 <= 'h' && y - 1 >= 1) ++count;
        if (x + 1 <= 'h' && y - 2 >= 1) ++count;
        if (x - 2 >= 'a' && y - 1 >= 1) ++count;
        if (x - 1 >= 'a' && y - 2 >= 1) ++count;

        printf ("%d\n", count);
    }
}
