Enumeration (or enum) in C - GeeksforGeeks
3 weeks ago - We can also confirm here that two enum names can have same value. Enum definition is not allocated any memory, it is only allocated for enum variables. Usually, enums are implemented as integers, so their size is same as that of int. But some compilers may use short int (or even smaller type) to represent enums.

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.

Declaring an enum variable is done like this:
enum strategy {RANDOM, IMMEDIATE, SEARCH};
enum strategy my_strategy = IMMEDIATE;
However, you can use a typedef to shorten the variable declarations, like so:
typedef enum {RANDOM, IMMEDIATE, SEARCH} strategy;
strategy my_strategy = IMMEDIATE;
Having a naming convention to distinguish between types and variables is a good idea:
typedef enum {RANDOM, IMMEDIATE, SEARCH} strategy_type;
strategy_type my_strategy = IMMEDIATE;
