c++ - 我已经写了一个代码直接从数组创建最大堆到一个创建的虚拟数组但是输出是错误的，有人可以指出错误

Question

int swap(int *dum ,int i, int temp)
{
    int j=*(dum+temp);
    
    *(dum+temp)=*(dum+i);// swapping numbers in index i and temp of array dum
    
    *(dum+i)=j;
    
     return 0;
}

int main()
{
    int a[6]={32,40,15,50,5,44};
    
    int n=6;
    
    int *dum=new int[n];
    
    for(int i=0;i<n;i++)
    {
        *(dum+i)=*(a+i);// assigning input array elements to a dummy error 
        
        if(i>0)
        {
            int temp=(i-1)/2;
            
            while(*(dum+i)>*(dum+temp))// checking if a particular node is larger than parent node data 
            {
                swap(dum,i,temp);// calling a function to swap the data a indices i and temp
                
                 i=temp;// i will now hold the index of parent of previous i
                
                temp=(i-1)/2;//temp will now hold parent of new i
             
                if(i==0)
                {
                    break;
                }
            }
        }
    }
    for(int i=0;i<n;i++)
    {
          cout<<*(dum+i)<<"\n";//print data members in dummy array
    }
}

OUTPUT:// 这是输出，想要的输出在它旁边

50 //50
50 //40
44 //44
50 //32
5 //15
44 //5
