struct - what is it for?

Question

I know something about struct type. But I can\'t understand: what is it for? when have I use it? Classes, simple value-types and enums - that\'s all that I need

Answer 1

If you don't know why you need it, you probably don't.

struct is a value type rather than a reference type. If you don't know what that means, then you probably aren't going to need it.
