// 复制文件

文件复制二
他人代码
#include <iostream>#include <fstream>#include<string>using namespace std; int main(){ ofstream outFile("destination.txt",ios::out); ifstream inFile("source.txt", ios::in); if (!(inFile && outFile)) { cerr << "File could not be opened!" << endl; exit(1); } string str; while (getline(inFile, str)) // 按行得到数据 { //要修改的话，在这里对str进行处理 outFile << str <<"/n"; } return 0;}
