  • 0

I read somewhere about giving enums default values like so:

typedef enum  {
MarketNavigationTypeNone = 0,
MarketNavigationTypeHeirachy = 1,
MarketNavigationTypeMarket = 2
} MarketNavigationLevelType;

.. but i can’t remember the value of doing this. If i don’t give them default values – and then someone later on reorders the enum – what are the risks?

If i always use the enum name and don’t even refer to them by their integer value, is there any risks?

The only possible problem i can think of is if i’m initialising an enum from an int value from a DB – and the enum is reordered – then the app would break.

    In general this only matters if the enum is exposed to some kind of external API or it is going to be used to exchange data via data files or other means. If the enum is only every used within your app and nowhere else then the actual values don’t matter.
