接受键盘输入的一组字符，输出其对应的霍夫曼编码

恰好和你心意 我自己编的~~~ 不过是C版本的哦 ，非C++~~

=============================================
#include<stdio.h>
#include<stdlib.h>
#include<string.h>
typedef struct htnode
{
int ww,parent,llink,rlink;
char cc,buffer[20]; //cc用来存放字母，buffer用来存放编码字符
}datatype;

struct httree
{
int m;
datatype * ht;
};
typedef struct httree * phttree;

phttree creatht(int m,char * n,int * w)
{
phttree pht;
int x1,x2,m1,m2;
pht=(phttree)malloc(sizeof(struct httree));
if(pht==NULL)
{
printf("申请空间失败！！\n");
return pht;
}
pht->m=m;
pht->ht=(datatype *)malloc(sizeof(datatype)*(2*m-1));
for(int i=0;i<2*m-1;i++)
{
pht->ht[i].llink=-1;
pht->ht[i].rlink=-1;
pht->ht[i].parent=-1;
if(i<m)
{
pht->ht[i].ww=w[i];
pht->ht[i].cc=n[i];
}
