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.

Answer 2

Yes: You can pass ints and floats into overloaded functions

No: You cannot overload/override the operators for built in types when the built-in types are on both sides of the expression.

Answer 3

No we cannot overload integer or float types because overloading means to change the working of existing operators or make them to work with objects int is single member not an object.
