Great to see you back! Now that you've got the basics of creating functions and using the return keyword, it’s time to take it a step further. In this lesson, we'll focus on how to make your functions more interactive and flexible by adding parameters. This new tool in your programming toolkit will allow your functions to take in data and perform tasks based on that input. Let's dive in!

You'll learn how to define a function that accepts parameters and how to pass arguments to these parameters when calling the function. As an example, we'll create a function called Navigate that takes a destination parameter and prints it out. Here’s a sneak peek:

C#
Copy to clipboard
1void Navigate(string destination)
2{
3    Console.WriteLine("Navigating to " + destination);
4}

You'll also practice calling this function with different arguments, like:

C#
Copy to clipboard
1Navigate("Mars");

This will help you understand how parameters enhance the reusability and flexibility of your functions.

Functions with parameters are incredibly versatile. By passing different arguments, you can use a single function to handle various tasks. Imagine you're controlling a spacecraft like and you need to navigate to different planets. With a parameter, you only need one function to handle all possible destinations. This makes your code more efficient and easier to manage.
