没有给time1编写默认构造函数，在类的定义里加一句time1():hour(0),minute(0),second(0){} int main(){time1 t1; //并没有在类中添加基础的构造函数，这一行可以改成time1 t1(time_t对象)cout << t1.printfUniversal();cout << "\nHello world!" << endl;return 0;}// class time...

Re: g++ "no matching function to call" using a template Replying to myself (but maybe of benefit to others): Apparently, the function return value (the one being return by f() in my example) is considered "const", and therefore the operator= and the copy constructor were not...
