When should you use a class vs a struct in C++?

Question：

In what scenarios is it better to use a struct vs a class in C++?

Answer：

The only difference between a class and a struct in C++ is that structs have default public members and bases and classes have default private members and bases. Both classes and structs can have a mixture of public and private members, can use inheritance,
and can have member functions.

I would recommend using structs as plain-old-data structures without any class-like features, and using classes as aggregate data structures with private data and member functions.
