#include "stdafx.h"
#include <iostream>
#include <fstream>
using namespace std;
int main()
{
//输出到磁盘
//打开文件
ofstream ofs("a.txt", ios::out);
ofs << "this is out!!" << endl;
ofs << "this is out!!" << endl;
//关闭文件
ofs.close();
//输入到程序
ifstream ifs("a.txt",ios::in);
char buf[80];
while (!ifs.eof())
{
ifs.getline(buf, 80);
cout << buf << endl;

}

ifs.close();
return 0;
