macOS fundamental C question: what is the syntax and usage of "in"

[Sydde]

I tend to have a fair number of conditionals (mostly if's) that have a lot of &&/|| structures. Is the "in" operator used to replace something like "if ( ( 3 == a )||( ( 5 < a )&&( 8 > a ) ) )", and if so, what is the syntax? I cannot seem to find "in" explained anywhere. I have only learned enough C to write working code, there are a few subtleties I am sure I have missed.

This keyword is used for fast enumeration in Objective-C:

this is not part of plain C, and is used to simplify loops over collections of objects. It is not used to simplify conditionals.
