What are the differences between struct and class in C++?

What are the differences between struct and class in C++?

In C++, the main differences between struct and class are access control and default inheritance. Struct members are public by default, while class members are private. Additionally, when inheriting from a struct, the default access is public, whereas for a class, it is private.

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

Sure! Use a struct when you want to create a simple data structure that primarily holds data without complex behavior. For example, a Point struct to represent coordinates might look like this: struct Point { int x; int y; };.

Are there any performance differences between using struct and class?

No, there are no inherent performance differences between struct and class in C++. Both are essentially the same in terms of memory usage and performance; the choice depends on design and access control.

Can structs have member functions?

Yes, structs can have member functions just like classes. The only difference is the default access level. You can define methods within a struct to operate on its data members.
