doing with the arguments:

what does the function do with 50 and 78?
also, my flaming shields are up. this is certainly very basic so
flame away
if you must, but i just can't remember coming across these functions
in any
of my c books.
They're not functions, they're macros. I don't think they're part of
the C standard, but they are very useful and usually one of the first
things that get added to a runtime.
MIN(a, b) returns the smaller value of a or b, and MAX( a, b ) returns
the larger value.
Note: Apple's current implementations of MIN and MAX don't nest well
if you have extra warnings enabled, because they use an internal local
variable called _a, which is true of both macros, so one ends up
shadowing the other. It's harmless, but slightly annoying.
