哪为高手能帮我写一个80——100条语句的C语言程序啊？

#include<string.h>
#include<stdlib.h>
#include<stdio.h>

int m,s1,s2;

typedef struct {
unsigned int weight;
unsigned int parent,lchild,rchild;
}HTNode,*HuffmanTree; //动态分配数组存储哈夫曼树
typedef char *HuffmanCode; //动态分配数组存储哈夫曼编码表

void Select(HuffmanTree HT,int n) {
int i,j;
for(i = 1;i <= n;i++)
if(!HT[i].parent){s1 = i;break;}
for(j = i+1;j <= n;j++)
if(!HT[j].parent){s2 = j;break;}
for(i = 1;i <= n;i++)
if((HT[s1].weight>HT[i].weight)&&(!HT[i].parent)&&(s2!=i))s1=i;
for(j = 1;j <= n;j++)
if((HT[s2].weight>HT[j].weight)&&(!HT[j].parent)&&(s1!=j))s2=j;
}

void HuffmanCoding(HuffmanTree &HT, HuffmanCode HC[], int *w, int n) {
// 算法6.13
// w存放n个字符的权值(均>0)，构造哈夫曼树HT，
// 并求出n个字符的哈夫曼编码HC
int i, j;
char *cd;
int p;
int cdlen;

if (n<=1) return;
m
