hey dudes pls help me on this. My program is crashing on the following piece of code

When i make 1 recurssive function to work, the program works without crashing. So I would really need help in spotting the mistake I have done.

Incase if you want to know what im trying to do-

I have wrote a function to spot all pixels of an image and it is used to find the centre of the image. Some variables like pixtot and xt are declared as global variables.

```
void neighbour(int x, int y){
if(s[y][x+1]<192){
xt=xt+(x+1);
neighbour((x+1),y);
pixtot++;
}
if(s[y][x-1]<192){
xt=xt+(x-1);
//neighbour((x-1),y); //<- crashes when comment slashes are taken out
pixtot++;
}
if(s[y+1][x]<192){
yt=yt+(y+1);
//neighbour(x,(y+1)); //<- crashes when comment slashes are taken out
pixtot++;
}
if(s[y-1][x]<192){
yt=yt+(y-1);
//neighbour(x,(y-1)); //<- crashes when comment slashes are taken out
pixtot++;
}
}
}
```

Thanks
