Aug 14, 2018 · Typically by overloading operator<< for your class: int i; return os << m.i; myclass x(10); std::cout << x; return 0; Note that if myclass has any private fields, and you want operator<<() to output them, myclass should declare std::ostream& operator<<(std::ostream&, myclass const&) as a friend.

In the class AutoData, you should declare this function: friend ostream& operator<< (ostream& out, const AutoData& obj); outside the class, you should define this function like this: ostream& operator<< (ostream& out, const AutoData& obj) { out<<obj.mpg<<":"; //do …
