C++ Structure vs Class

What is the difference between a structure and a class in C++?

In C++, both structures and classes are used to create user-defined data types, but they have some key differences. Structures default to public access, while classes default to private. Additionally, classes can have member functions, while structures are typically used for simple data grouping.

Can you give me an example of when to use a structure instead of a class?

Sure! Use a structure when you need a simple data container without complex behavior, like a point in 2D space with x and y coordinates.

Are there any performance differences between using a structure and a class?

Generally, there are no significant performance differences between structures and classes in C++. The choice depends more on design and access control rather than performance.

Can structures have member functions?

Yes, structures in C++ can have member functions, just like classes. The main difference lies in the default access specifier.
