4. Functions

Functions are essential building blocks in programming that encapsulate code to perform specific tasks, promoting modularity and reusability. Various types of functions include library and user-defined functions, each serving different purposes. The knowledge of function parameters, overloading, and their types enhances a programmer's ability to write clear and efficient code.
