What is a Function in Computer Programming
Introduction In programming, functions are a vital part of code organization and reusability. A function is a block of code that performs a specific task, making it a basic concept in various programming languages like Python, C++, PHP, and JavaScript. This article explores the essence of functions, provides code examples in these languages, distinguishes between custom and built-in functions, and explains how to implement default values for function arguments. Concept of Functions A function serves as a self-contained unit of code designed to execute a particular job. It streamlines complex tasks, promotes code modularity, and facilitates code maintenance. To understand functions better, let's break down their core components. Anatomy of a Function A function typically consists of the following elements: Function Declaration/Definition : This is where you define the function's name, list its parameters (inputs), and possibly specify its return type. Function Body : W...
