The+operator, when used with values of typeint, returns their sum. However, when used with objects of a user-defined type, it is an error. In this case, we can define the behavior of the+operator to work with objects as well.
The overloads of operator>> and operator<< that take a std::istream& or std::ostream& as the left hand argument are known as insertion and extraction operators. Since they take the user-defined type as the right argument (b in a @ b), they must be implemented as non-members. ...

For up-to-date information on C++, see the main reference at cppreference.com. Operator overloading in C++ allows us to write natural expressions like d = a + b / c; with our own classes. The above expression could be equal to d = a.add(b.divide(c)); which results in hard ...
