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

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

In C++, the main differences are: structs default to public access, while classes default to private. Also, structs are typically used for plain data structures, while classes are used for more complex data types with methods.

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

Sure! Use a struct when you need a simple data structure to group related variables, like a Point with x and y coordinates. Classes are better for objects with behavior.

Are there any performance differences between using structs and classes?

No, there are no inherent performance differences. Both are treated similarly by the compiler, but the choice depends on design and readability.

Can structs have methods like classes?

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

What about inheritance? Can structs inherit from classes?

Yes, structs can inherit from classes and vice versa. The access specifier used will determine the visibility of the inherited members.
