How much functionality is “acceptable” for a C++ struct?

Question

My first post so please go easy on me!

I know that there\'s no real difference between structs and classes in C++, but a lot of people including me use a struct or class

Answer 1

Generally, I use class whenever I need to use access specifiers. This has the effect that most of my top-level stuff remain as classes, while the rare POD collections and my not-so-rare inner-class pimpls are usually structs.
