What is the difference between structs and classes in C++?

What is the difference between structs and classes in C++?

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

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

Sure! You might use a struct for a simple data structure like a point in 2D space, where you just need to store x and y coordinates without any additional functionality.

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 access control rather than performance.

Can structs have member functions?

Yes, structs can have member functions just like classes. The only difference is the default access level.
