Re: Clever UNIX/C Constructs

[Jim Langston <jimlangston@xxxxxxxxxxxxxxxx>]

I've used += -= in C and they're okay, but I don't really need them.

The one I really find a headache is the ++ and -- cause that just makes
me have to think way to much to decipher a line of code.

Myvar(n++) += MyVar(--m)

That line of code is doing 3 different things at once.  
1. Subtracting 1 from m
2. Adding MyVar(m) to MyVar(n)
3. Adding 1 to n
in that order.

That is tame from some of the ones I've seen.  It gets so complicated that
it becomes very difficult to maintain.  I would much prefer:
M = M - 1
MyVar(n) = MyVar(n) + MyVar(m)
N = N + 1

Now I know what it's doing without having to decipher it.  I can live with
it if we use those constructs, but IMO we are much better off putting our
money into more useful functions.

Regards,

Jim Langston
