Funktione

Funktione is a programming concept that represents a block of code designed to perform a specific task. It takes input values, known as arguments, and can optionally produce an output value, called a return value. Functions are fundamental building blocks in most programming languages, promoting modularity and reusability.

By encapsulating a set of operations within a function, developers can break down complex problems into smaller, manageable pieces. This makes code easier to understand, debug, and maintain. A function is typically defined with a name, a list of parameters (which are placeholders for the arguments it will receive), and a body containing the executable statements. When a function is called, the code within its body is executed, and if a return value is specified, it is sent back to the part of the program that invoked the function.

The use of functions helps to avoid repetitive code. Instead of writing the same sequence of instructions multiple times, a function can be written once and called whenever that particular task needs to be performed. This principle is known as DRY, or "Don't Repeat Yourself." Functions can also be designed to be independent of other parts of the program, making them easier to test and reuse in different contexts or even in entirely different projects. This modular approach is key to developing robust and scalable software.
