It's worth pointing out that you don't need a typedef
. You can just do it like the following
enum strategy { RANDOM, IMMEDIATE, SEARCH };
enum strategy my_strategy = IMMEDIATE;
It's a style question whether you prefer typedef
. Without it, if you want to refer to the enumeration type, you need to use enum strategy
. With it, you can just say strategy
.
Both ways have their pro and cons. The one is more wordy, but keeps type identifiers into the tag-namespace where they won't conflict with ordinary identifiers (think of struct stat
and the stat
function: these don't conflict either), and where you immediately see that it's a type. The other is shorter, but brings type identifiers into the ordinary namespace.
