Can Operators Be Overloaded for Intrinsic Types?

In C , it is possible to overload operators for user-defined types. However, the intrinsic types such as int and float are not user-defined, so the question arises: can their operators be overloaded?

As stated in the provided answer, it is not possible to redefine built-in operators. Operator overloading is a mechanism that allows developers to extend the language by defining custom behavior for operators in the context of their own types. This feature was designed to enhance the expressiveness and extensibility of the language, without modifying its core functionality.

Therefore, at least one of the parameters of an overloaded operator must be a user-defined type (a class or enum) or a reference to such a type. Intrinsic types like int and float do not fall under this category, so they cannot be used as parameters in operator overloading. Consequently, you cannot declare a function such as int operator (int , int); in C .
