can you tell me whats wrong in this code

#include<bits/stdc++.h>

#define ll long long

using namespace std;

int r,d,i,j;

int find( int c,void *x,int i, int j, int v,int h)

{ int (*arr)[c] = static_cast<int (*)[c]>(x);

if(i==r && j==c)return 1;

else if(arr[i][j]==0)return 0;

else if(v==d+1 || h==d+1)return 0;
