Because I encountered a problem when I wrote a small program myself, it is not acceptable for some operator to be defined as a member function, but it is OK to define it as a friend, and some do not understand it, it is
Clause 24 explains why only non-member functions can "implement implicit type conversion on all real parameters ". These terms templated rational and operator:
Template Class rational {Rational (const T & number = 0,Const T & Denominator = 1

C ++ Operator OverloadingThe operation objects of pre-defined operators in C ++ can only be basic data types. However, similar operations are also required for many user-defined types (such as classes. In this case, you must redefine these operators
Operator is a C + + keyword that is used in conjunction with an operator to represent an operator function that should be understood as a function name as a whole operator=.This is a method of the C + + extension operator function, although it looks
