c++ mark enum value as deprecated?

Question

Is it possible to mark an enum value as deprecated?

e.g.

enum MyEnum {
    firstvalue = 0
    secondvalue,
    thirdvalue, // deprecated
    fourthva         


        

Answer 1

Using compiler dependent pragmas: Here is the documentation for Gcc and Visual Studio.

Answer 2

You can declare enum constants outside an enum declaration:

enum MyEnum {
    firstvalue = 0
    secondvalue,
    thirdvalue
};
__attribute__ ((deprecated)) const MyEnum fourthvalue = MyEnum(thirdvalue + 1);
