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

When, if ever, should one use a STRUCT declaration rather than a CLASS declaration when writing a program using C++?

1. Never !! ?
2. Any thing…whichever makes one feel better?

Answer 1

The only difference between the two is that by default struct are public while class members are private.

My rule is to use struct when I mean a clump of related data without any special semantics on reading/writing them. Use class when I intend to wrap the data in richer semantics (read methods) that are more meaningful, provide any needed protection, or implement something more abstract.
