Is enum from the C programming language?

I have been looking through the original GL quake gaming engine, and it's completely written in C(edit: also x86 asm). There are a lot of #defines, and instead of using the #defines enumerated constants could've been used instead, unless of course enum isn't a part of the C programming language.

yes c has enums but they are not quite the typesafe enums of c++

could you elaborate with an example or something?

in c an enum is seen by the compiler as an int. in c++ the enum is a distinct type.

enums in C++ are still assigned integer values though.
