Why should I have an enumeration declared using typedef in C ++?

Question

I had code that looked like this:

enum EEventID {
  eEvent1,
  eEvent2,
  ...
  eEventN };

And it was reviewed and changed to

typedef enum {
  eEvent1,
  eEvent2,
  ...
  eEventN } EEventID;

What is the difference between the two? Why make a change? When I looked at this question , the only mention of typedefs was omitted.

Answer 1

Both are identical in C ++, but they are not the same in C - in C, if you use typedef, you get code compatible between C and C ++ (therefore, it can be used freely in the header file, which can be for C or C + +). This is the only reason I may prefer it.

Answer 2

: ", C, , enum , , enum struct ."

, - C-, , .

Answer 3

, . C, .

Answer 4

typedef is superfluous in C ++ .
The C is necessary if you want to determine your type of the variables listed in the following way: EEventID event;otherwise you would have to specify its transfer: enum EEventID event;.

Answer 5

Your reviewer does not know his C from his C ++.
