What are the differences between structs and classes in C?

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

In C, structs are used to group related variables, while classes are a feature of C++ that support encapsulation and inheritance.

Can you explain encapsulation in classes?

Encapsulation is the concept of restricting access to certain components of an object, allowing only specific methods to interact with its data.

Are there any performance differences between using structs and classes?

Generally, structs and classes have similar performance, but classes may have overhead due to features like inheritance and virtual functions.

When should I use a struct instead of a class?

Use structs for simple data structures without behavior, and classes for more complex objects that require methods and encapsulation.
