The function doesn't work. What to do?

Question

C++ / C#

void swap(int *a,int *b){
    int temp=*a;
    *a=*b;
    *b=temp;
}
int parent(int i){
   return (i-1)/2;
}
void shitf_up(binary_tree *s,int pos){
   int Parent=parent(pos);
   if (pos>0 && (s->val[pos] > s->val[Parent])){
       swap(&s->val[pos],&s->val[Parent]);
       shitf_up(&s,Parent);
   }
   return;
}

Guys, the shift_up function does not work. Can you give me some idea why it doesn't work. Thanks in advance.

Answer 1

So far I can see ...
shitf_up(s,Parent);
Maybe you also messed up with the order of the heap, but this is not visible on such a piece of code.
