From time to time I see something like this:
class Clazz {
private int _goodName;
private int _anotherGoodName;
...
}
I don’t get it. It’s hard and unusual to read such code. What are the pros?
It’s a naming convention used by some people to indicate “these are private variables”.
Personally I’m not a fan as I think you can leave off the underscore and achieve the same result, but to each his own. I think it may have it’s roots in pre-IDE days when you might be viewing a method and the visibility/ownership of certain variables is not always clear.
