How to add an enum or enumeration to a class in C++?

Obviously this is simple, but I keep forgetting one element or other of the syntax (usually the terminating semi-colon) so I thought if I made a post about it, I would never forget again, and if I did, I could look at my post and remember.

There are certain parts to an enum configuration:

1. The enum keyword.
2. The name of the enumerator. I name this one Items just as an example but it can be named anything you want almost (of course you can’t use C++ keywords).
3. The open bracket: {
4. The names of the items separated by comas:
   item1, item2, item3
   Each item has an integer value starting at 0 and incrementing by one. Optionally, you can change a value, and again, ever value thereafter will be +1. So if you want to start at 1 instead of at 0, you would put this:
   item1 = 1, item2, item3
   If you wanted to count from 1,2,3 and then 7,8,9 you could do this:
   item1 = 1, item2, item3, item7 = 7, item8, item9
   Also you can change every item by having every item by assigning every item.

5. The closing bracket: }
6. A statement closing semicolon: ;

   So the code for your Items enumerator look like this:

   enum Items
   {
       item1 = 1, item2, item3
   };
   

   A basic class is shown here:

   class NewObject
   {
   public:
       // Public members and functions
       NewObject();
       ~NewObject();
   protected:
       // Protected members and functions
   private:
       // Private members and functions
   };
   

   So to add an enum to you need to decide, is it a public, protected, or private enum? I think it is most common to have public enumerations so that is what my example shows.

   class NewObject
   {
   public:
       // Public members and functions
       NewObject();
       ~NewObject();
   
       enum Items
       {
           item1 = 1, item2, item3
       };
   
   protected:
       // Protected members and functions
   private:
       // Private members and functions
   };
   

   Now you can use the enum on any instantiated class.
