What is Functions?

In programming, functions are self-contained blocks of code that perform a specific task. They are designed to be reusable, meaning they can be called multiple times from different parts of a program without having to rewrite the code. Functions typically accept input values (arguments or parameters), perform operations on those values, and then return an output value. They promote modularity, making code easier to understand, debug, and maintain. Common uses include organizing code into logical units, reducing code duplication, and encapsulating complex operations.
