Objective-C / C giving enums default values

Question

I read somewhere about giving enums default values like so:

typedef enum  {
MarketNavigationTypeNone = 0,
MarketNavigationTypeHeirachy = 1,
MarketNavigationTypeM         


        

Answer 1

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.
