Why do you use typedef when declaring an enum in C++?

Question

I haven\'t written any C++ in years and now I\'m trying to get back into it. I then ran across this and thought about giving up:

typedef enum TokenType
{
            


        

Answer 1

In C, it is good style because you can change the type to something besides an enum.

typedef enum e_TokenType
{
    blah1   = 0x00000000,
    blah2   = 0X01000000,
    blah3   = 0X02000000
} TokenType;

foo(enum e_TokenType token);  /* this can only be passed as an enum */

foo(TokenType token); /* TokenType can be defined to something else later
                         without changing this declaration */

In C++ you can define the enum so that it will compile as C++ or C.
