Can we Overload Operators for Built-in Types like `int` or `float` in C ?

Operator Overloading for Built-in Types

Operator overloading is a powerful feature that allows us to extend the functionality of built-in operators to our own custom types. However, a common question arises: can we use operator overloading to redefine operators for built-in types like int or float?

Question:

Can we declare a function like the following in C :

<code class="cpp">int operator + (int, int);</code>

Answer:

No, we cannot redefine a built-in operator for a built-in type. Operator overloading is designed to allow us to extend the language with new capabilities, rather than alter the existing ones. Therefore, at least one of the parameters of an overloaded operator must be either a user-defined type (class or enum) or a reference to one.
