第17行使用member function的方式overload + operator,18行使用global function的方式overload * operator,這兩種寫法都可以,惟若使用global function,由於要存取data menber,所以要宣告該function為friend,這樣才能存取data member。 19行我們overload了<< operator,由於也是global function,所以也要宣告friend。 最後49行...

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.
When an operator appears in an expression, and at least one of its operands has a class type or an enumeration type, then overload resolution is used to determine the user-defined function to be called among all the functions whose signatures match the following: ...

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 ...
