C Structures vs Classes: What's the Difference?

What are the main differences between structures and classes in C?

In C, structures are used to group different data types, while classes are a feature of C++ that support encapsulation, inheritance, and polymorphism.

Can you explain how encapsulation works in classes?

Encapsulation in classes restricts access to certain components, allowing only specific functions to interact with the data, thus protecting it from unauthorized access.

Are there any performance differences between using structures and classes?

Generally, structures and classes have similar performance in C++, but classes may introduce some overhead due to features like inheritance and virtual functions.

When should I use a structure instead of a class?

Use structures when you need a simple data grouping without the need for encapsulation or complex behaviors, typically for plain data.
