Explanation

Operator overloading allows programmers to redefine how built-in operators (like +, -, *, etc.) work with user-defined objects or data types. This enables intuitive syntax (e.g., adding complex numbers with a+b) and is a key feature of C++ polymorphism. It has nothing to do with overheating, parallel processing, or deadlock avoidance.
