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

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

In C++, both structs and classes are used to create user-defined types, but they have some key differences. Structs default to public access, while classes default to private. Additionally, structs are typically used for simple data structures, whereas classes are used for more complex data types with methods.

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

Sure! You might use a struct when you want to group related data together without needing to encapsulate behavior. For example, a Point struct with x and y coordinates is a good candidate for a struct.

Are there any performance differences between using structs and classes?

Generally, there are no significant performance differences between structs and classes in C++. The choice between them is more about design and readability than performance.

Can structs have member functions?

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