Binary Operators as Member Functions

An operator may be defined as a member function of a class.
The operator is invoked by the left operand of the expression.
The expression a + b is equivalent to a.operator+(b)
Advantages
- The operator has access to the private members of the operands.
Disadvantages
- If a and b are objects of different classes, then a + b and b + a are interpreted differently.
