堆排序(大根堆)

注：数组是从arr[1]开始排序

#include
using namespace std;
//大根堆 
void HeapAdjust(int arr[],int s,int m){
	int rc = arr[s];
	for(int j=2*s;j<=m;j*=2){
		if(j=arr[j]) break;
		int temp = arr[s];
		arr[s] = arr[j];
		arr[j] = temp;
		s = j;
	}
	arr[s] = rc;
}
void CreatHeap(int arr[],int n){
	for (int i=n/2;i>0;--i){
		HeapAdjust(arr,i,n);
	}
}

void HeapSort(int arr[],int n){
	CreatHeap(arr,n);
	for (int i=n;i>1;--i){
		arr[0] = arr[1];
		arr[1] = arr[i];
		arr[i] = arr[0];
		HeapAdjust(arr,1,i-1);
	}
}
void printarray(int arr[],int n)
{
      for(int i=1;i<=n;i++)
            cout<>n;
	int arr[n+1];
	for(int i=1;i<=n;i++){
		cin>>arr[i];
	}

    cout<<"oarray:";

    printarray(arr,n);

    HeapSort(arr,n);
    
    cout <<"sarray:";

    printarray(arr,n);

    return 0;
