decode.h

实现了对文本文件的huffman编码与解码过程

#include <fstream>
#include <iostream>
#include <string>
using namespace std;

void Decode(string infilename, string outfilename, int wordnumber[], string str[])
{
	const char *out = outfilename.c_str();
	const char *in = infilename.c_str();
	ofstream outfile(out);
	ifstream infile(in);
	int x;
	char c;
	string store;
	while(!infile.eof())
	{
		infile.get(c);
		store.append(1,c);
		int i;
		for(i=0; str[i]!=""; i++)
		{
			if(store == str[i])
			{
				x = wordnumber[i];
		        c = x+97;
				outfile<<c;
				store.clear();
			}
		}

	}
	outfile.close();
	infile.close();
}
