往文件中写入内容（代码示例）

将字符写入到文本文件中：

#include "stdafx.h"#include<fstream>#include <iostream>using namespace std;int main(){ofstream out;out.open("test.txt");

        //ofstream out("test.txt");if (!out){cerr << "failure" << endl;return 0;}for (int i = 0; i < 10; i++){out << i;}cout << endl;out.close();return 0;}
