frequent.cpp

该程序用ＶＣ实现了一个小型文件压缩与解压缩功能的程序

#include"Frequent.h"
void Frequent::Analyze(char* filename,HashTable<chNode>& HTable)
{
		ifstream fin;
		char temp;
		chNode Node;
		fin.open(filename);
		if(!fin){
			cout<<"The file does not eist!"<<endl;
			exit(1);
		}

		while(fin.get(temp)){
			Node = chNode(temp);
			if(HTable.Find(Node)!=NULL){
				Node.fre++;
			HTable.Update(Node);
			}
			else{ 
				Node.fre=1;
				HTable.Insert(Node);
			}
		}	
		cout<<endl;
	}
