c – 最大堆实现

#include<iostream>
#include<math.h>
using namespace std;
#define  maxn 1000
int x[maxn];

int parent(int i){
    return int(i/2);

}
int left(int i){
    return 2*i;

}
int right(int i){
    return 2*i+1;

}
void  max_heap(int x[],int i,int size){
    int largest;
    int l=left(i);
    int r=right(i);

    if (l<=size &&  x[l]>x[i]){
        largest=l;
    }
    else
    {
        largest=i;
    }
    if (r<=size && x[r]>x[largest]){
    largest=r;
    }
    if (largest!=i)  { int s=x[i];x[i]=x[largest];x[largest]=s;}
    max_heap(x,largest,size);
}




int main(){

 x[1]=16;
 x[2]=4;
 x[3]=10;
 x[4]=14;
 x[5]=7;
 x[6]=9;
 x[7]=3;
 x[8]=2;
 x[9]=8;
 x[10]=1;
  int size=10;
  max_heap(x,2,size);
   for (int i=1;i<=10;i++)
       cout<<x[i]<<"  ";






    return 0;
}

当我运行它时,会写出这样的警告：

1>c:usersdatuashvilidocumentsvisual studio 2010projectsheap_propertyheap_propertyheap_property.cpp(36): warning C4717: 'max_heap' : recursive on all control paths,function will cause runtime stack overflow

请告诉我有什么问题？
