1. Operator OverloadingThe mechanism to give special meaning to the operator is knows as operator overloading.We can overload all C++ operators except the following:Class member access operator( . And *)Scope resolution operatorsizeof operatorConditional operator
2. We can redefine or overload most of the built-in operators available in C++. Thus a programmer can use operators with user-defined types as well.Overloaded operators are functions with special names the keyword operator followed by the symbol for the operator being defined. Like any other function, an overloaded operator has a return type and a parameter list.
3. Operator overloading cannot be used to change the way operator works on built-in types. Operator overloading only allows to redefine the meaning of operator for user-defined types.Operator overloading cannot change the precedence of operators and associativity of operators. But, if you want to change the order of evaluation, parenthesis should be used.
4. Syntax for operator overloadingFollowing is the syntax for using operator overloading when defining it inside the class definition: return type operator op_sign (parameter list) { …………. }And outside the class: return type class name :: operator op_sign (parameter list) { …………. }
