CH - 6 Functions

Discusses functions, and how they promote readability, modularity, and overall quality of code

A function is a block of reusable code that performs a specific task. Functions help to make your code more organized and manageable by allowing you to group related instructions into a single unit.

• Functions can take parameters, which are inputs that modify the way the function behaves. For example, a function that calculates the area of a rectangle might take the rectangle’s width and height as parameters.
• Functions can also return values, allowing you to get results back after performing calculations or processing data.

Using functions is essential for writing clean and efficient code. By breaking down complex tasks into smaller, reusable functions, you make your programs easier to read, debug, and maintain.
