求解 这是一个哈夫曼的函数

我知道是指针错了···但是不知道怎么改 谁能帮帮忙啊···

#include "stdafx.h"#include <stdio.h>#include <malloc.h>#include <string.h>#include<iostream.h>
#define UINT_MAX 1000
typedef struct { unsigned int weight; unsigned int parent,lchild,rchild; }HTNode,*HuffmanTree;
typedef char **HuffmanCode;
int min(HuffmanTree t,int i)
{
int j,f;
unsigned int k=UINT_MAX;
for(j=1;j<=i;j++)
if(t[j].weight<k&&t[j].parent==0)
k=t[j].weight,f=j;
t[f].parent=1;
return f;
}
void select(HuffmanTree t,int i,int &s1,int &s2)
{ int min(HuffmanTree t,int i);
int j;
s1=min(t,i);
s2=min(t,i); if(s1>s2)

s1=s2;
s2=j;
}
}

这是代码··
