What are some alternatives to using global variables in programming?

There are several alternatives to global variables, such as using function parameters, return values, and encapsulating data within classes.

Can you explain how encapsulating data within classes works?

Sure! Encapsulation involves bundling the data (attributes) and methods (functions) that operate on the data into a single unit or class, which helps to restrict access to some of the object's components.

What are the benefits of using function parameters instead of global variables?

Using function parameters improves code readability, reduces side effects, and makes functions more reusable and easier to test.

Are there any downsides to avoiding global variables?

Yes, while avoiding global variables can lead to cleaner code, it may also require more complex data passing and management, especially in larger applications.
