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

You could look at what the Standard Library does. Everyone's favourite struct std::pair only has constructors.

I find the use of constructors with structs so convenient and natural that I can't imagine doing without them. I never give structs any other methods, but of course there may be free functions or members of other classes that take them as parameters.
