First, do not use structs in C++ code. Sadly, we

What's wrong with using 'struct'?

I prefer classes.

..and the difference is?

Methods and serialization.

   The difference between classes and structs is ??methods
   and serialization???

   To simplify the discussion, let me ignore ??serialization??.
   Then, I get:

       ??The difference between classes and structs is methods.??

   Does not sound like English to me, possibly because the
   singular ??is?? does not align well with the plural ??methods??.
   I can't make sense of it. But I am not a native reader of
   English.

If you care to learn, I'd venture to explain. "The difference is
methods" is a contracted sentence in which "the presence of" is omitted
before "methods", which in complete form would be "the difference is the
presence of methods" (feel free to replace "presence" with "existence"
or "ability to have" or some other synonym).

Doesn't make the statement any more true, of course, but that's not the
point.
