When should I use a class in C++?

When should I use a class in C++?

You should use a class in C++ when you want to encapsulate data and functions that operate on that data, promoting code reusability and organization.

Can you give me an example of when a class would be beneficial?

Sure! For instance, if you're creating a program to manage a library, you could create a 'Book' class to represent each book's attributes like title, author, and ISBN.

What are the advantages of using classes over structs?

Classes provide better data encapsulation and can include methods, while structs are typically used for simple data structures without behavior.

Are there any downsides to using classes?

Yes, using classes can introduce complexity and overhead, especially if not needed for simple data structures.
