哈夫曼编码C语言实现,哈夫曼在上世纪五十年代初就提出这种编码时,根据字符出现的概率来构造平均长度最短的编码。它是一种变长的编码。在编码中,若各码字长度严格按照码字。
用C语言编程实现赫夫曼编码 include#include#include#include#include using namespace std;typedef char*HaffmanCode;typedef struct { unsigned int weight;unsigned int parent,lchild,rchild;。
数据结构c语言版中 cd[-- start ]=“0”什么意思 求赫夫曼编码那一节 就是把cd数据的第start-2个字符(或数)变成字符0(或数字48)
c 语言赫夫曼编码完整的谁有啊??要有详细注释的啊 /HuffmanCoding.cpp/This function is to create HuffmanTree code#include<;stdio.h>;#include<;malloc.h>;#include<;iostream>;#include<;conio.h>;#include<;string.h>;using namespace std;define MAX_LENGTH 100typedef char*HuffmanCode;typedef struct/define structure HuffmanTree{ unsigned int weight;unsigned int parent,lchild,rchild;}HTNode,*HuffmanTree;void Select(HuffmanTree HT,int i,int&s1,int&s2)/Select sub-function{ int j,k=1;s1 is the least of HT[].weight while(HT[k].parent。0)/s2 is the second least of HT[].weight k+;s1=k;for(j=1;j;j)if(HT[j].parent=0&HT[j].weight[s1].weight)s1=j;k=1;while((HT[k].parent。0|k=s1))k+;s2=k;for(j=1;j;j)if(HT[j].parent=0&HT[j].weight[s2].weight&j。s1)s2=j;}/Select()endvoid HuffmanCoding(HuffmanTree&HT,HuffmanCode&HC,int*w,int n)/sub-function{ int m,i,s1,s2,start,c,f;HuffmanTree p;if(n)return;m=2*n-1;HT=(HuffmanTree)malloc((m+1)*sizeof(HTNode));for(p=HT+1,i=1;i;i,+p,+w)/initial HT[1.n]{ p->;weight=*w;cout[\"].weight=\"<;<;p->;weight;p->;parent=0;p->;lchild=0;p->;rchild=0;} 。
赫夫曼编码的设计与实现 includeusing namespace std;struct coder {long long v;char blen;};typedef struct coder scoder;struct htree {int v;char c;struct htree*left;struct htree*right;};typedef struct htree shtree;class huffman {public:huffman(unsigned int nodenum);huffman();shtree*CreateHuffman(const char*cset,const int*fset,int len);void TraverseHuffmanTree(void(*traverse)(char c,scoder hf),shtree*tree);void GetHuffmanCode(const char*str,unsigned char*out,int&len);private:htree*m_nodeList;unsigned int m_len;};huffman:huffman(unsigned int charnum){m_nodeList=new shtree[3*charnum-1];m_len=3*charnum-1;}huffman:~huffman(){delete[]m_nodeList;}shtree*huffman:CreateHuffman(const char*cset,const int*fset,int len){for(int i=0;i;i+){m_nodeList[i].v=fset[i];fset必须已升序排列m_nodeList[i].c=cset[i];m_nodeList[i].left=NULL;m_nodeList[i].right=NULL;}shtree*m_stack=m_nodeList;shtree*m_stackBack=m_nodeList+m_len-1;for(int i=0;i;i+){头两个最小节点入back栈m_stackBack-=*m_stack;m_stackBack-=*(m_stack+1);两。
