What does the “private” modifier do?

Question

Considering \"private\" is the default access modifier for class Members, why is the keyword even needed?

Answer 1

Some coding styles recommend that you put all the "public" items first, followed by the "private" items. Without a "private" keyword, you couldn't do it that way around.

Update: I didn't notice the "c#" tag on this so my answer applies more to C++ than to C#.
