Macros vs Inlines

Why do so many C programmers define stuff like min and max as macros?

I see stuff like #define MIN(a, b) (a < b ? a : b) everywhere, but then you get issues if you do stuff like MIN(a++, b--). If MIN was an inline function you wouldn't get undefined behavior like that.

Is it because C doesn't have overloadable functions, so you can't define a single MIN that works with every type of number?

[/o]You don't because the all-caps name reminds you that it's a macro and you shouldn't put expression with side-effects in its invocation. Alternatively, you can use Amplified C[sup]http://voodoo-slide.blogspot.com/2010/01/amplifying-c.html[/sup].
