what's the bug of my code

Code: Select all

#include <stdio.h>

#define N 0
#define S 1
#define E 2
#define W 3
#define NONE 4
#define VISIT 5

int a[66][66], t, m, n, i, j, c;
char s[1000];

void fill(int i, int j, int dir)
{
	if (i >= 0 && j >= 0 && i < m && j < n && a[i][j] != VISIT && a[i][j])
	{
		printf("%d %d\n", i, j);
		int tmp = a[i][j];
		if (i == m-1 && j == n-1 && dir != NONE)
		{
			c++;
			return;
