复制文件中的内容到另一个文件

// C   String.cpp : Defines the entry point for the console application.//#include "stdafx.h"#include<iostream>#include<fstream>#include<cstring>int main(int argc, char* argv[]){using namespace std;char arrstr[1024]  ;ifstream in;ofstream out;in.open ("studentInfo.txt");out.open ("studentInfo1.txt");if(in.fail()){cout<<"open file failed";exit(1);}if(out.fail()){cout<<"open file failed";exit(1);}int i = 0;while( !in.eof() ){in.getline(arrstr,1024);out<<arrstr<<endl;i++;}cout<<i<<endl;return 0;}

最后输出读取的行数
