Can we overload operators for built-in types like int or float?

Question

Can we declare a function like this in c++:

int operator + (int , int); 

Your answers will be appreciated!

Thanks

Answer 1

You cannot redefine a built-in operator. Operator overloading is designed to allow you to extend the language, not to change it. At least one of the parameters of an overloaded operator must be a user defined type (class or enum type) or a reference to a user defined type.
