Can You Overload Operators for Built-in Types like \'int\' or \'float\' in C ?

Overloading Operators for Built-in Types

Can we redefine built-in operators like ' ' for basic data types like 'int' or 'float' in C ? Let's explore the details and limitations of operator overloading.

In C , operator overloading allows developers to extend the capabilities of built-in operators for user-defined types. However, it is not possible to redefine built-in operators for primitive data types like 'int' or 'float'.

The primary purpose of operator overloading is to enhance language functionality rather than modify existing operations. To overload an operator, at least one of the parameters must belong to a user-defined type (class or enum) or be a reference to it.

In the example provided:

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

Both parameters are of the 'int' type (a built-in type). Since neither parameter is a user-defined type, it is not allowed according to the rules of operator overloading.

Therefore, it is important to remember that while operator overloading is a powerful tool for extending C 's functionality, it is limited to user-defined types, and built-in types like 'int' and 'float' cannot be modified using operator overloading.
