When should I use a class instead of a struct?

When should I use a class instead of a struct?

You should use a class when you need encapsulation, inheritance, or polymorphism. Structs are best for simple data structures.

Can you explain encapsulation and why it's important?

Encapsulation is the bundling of data and methods that operate on that data within one unit. It helps protect the integrity of the data.

What about performance? Are classes slower than structs?

Classes can have a slight overhead due to features like inheritance and polymorphism, but the difference is often negligible for most applications.

Are there any scenarios where I should prefer structs over classes?

Yes, use structs for small, simple data types that don't require inheritance or complex behavior, like representing a point in 2D space.
