读取代码段

使用ifstream 然后对C++进行文件的读取

int main() {    string buffer, filepath = "test.txt";    ifstream myfile(filepath.c_str());    //等同于 ifstream myfile("test.txt");    while(getline(myfile, buffer)) {        cout << buffer << endl;    }    myfile.close();    return 0;}

使用ofstream 然后对C++进行文件的写入

写入代码段

int main() {    string filepath = "test.txt";    //ofstream myfile("test.txt");    ofstream myfile(filepath.c_str());    myfile << "hbhh" << endl;    myfile << "aaaaa" << endl;    myfile.close();    return 0;}
