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

I always use structs for 'lumps of data', even if they get decorated with a constructor and sometimes comparison operators, they never get methods added to them (not even get/set methods).

I think this shows the intent of the type - a struct is just data to be operated on by other things.
