Function Implementation and Usage

A function, in programming, is a block of code designed to perform a particular task. Functions are defined with a specific name and can be called or invoked from other parts of the code. They can accept inputs, known as parameters, and often return an output after execution. Functions are fundamental to modular and reusable code, allowing developers to break down complex problems into manageable parts. Properly implemented functions improve code readability, maintainability, and efficiency.
