简单明了的C++文件操作之写文件

#include<io.h>#include<iostream>#include<fstream> //文件操作必须的头文件using namespace std;int main() {    ofstream outfile1;    //outfile1.open("D:\\data.txt",ios::app);//以追加方式打开    outfile1.open("D:\\data.txt");           //重写方式打开    outfile1 << "hello"<< endl;              //endl是换行    outfile1.flush();                        //将缓冲区的输出    outfile1.close();                        //关闭流    return 0;}
