Welcome to a new episode where we're shifting our focus from data structures to modularity of code! 🧑‍💻 Today, we're diving into Period 10: Functions & Procedures, a cornerstone of good programming practice. Our goal is to help you describe and implement functions and procedures with parameters.We'll start by exploring the numerous benefits of modular programming. We'll discuss how breaking your code into smaller, manageable chunks allows for code reuse, makes editing and debugging much easier, and simplifies team collaboration. Imagine you're working on a large program; it's much more efficient to have a single, reusable function for a task than to rewrite the same block of code multiple times.Functions vs. Procedures 🎯Next, we'll clearly differentiate between a function and a procedure. A function is a block of code designed to perform a specific task and return a single value (e.g., a function that calculates and returns the area of a rectangle). In contrast, a procedure is a block of code that carries out a task but may not return a value (e.g., a procedure that simply displays a message to the user).We'll use a classic example to illustrate these concepts: a modular solution for calculating the area of a rectangle. We'll identify the functions (like getDetails and calcArea) and the procedure (dispArea) within this solution. We'll also break down the concept of formal and actual parameters, explaining how they are used to pass data into these modular blocks. We'll use simple diagrams and examples to make this clear.
