You can also try

switch(true){

case(val>1 && val<35): do something;break;
case(val>=35 && val <53):do something;break;



[please quote, usenet is not email]

is the above really more useful than:

if (val>1 && val<35) do_something;
if (val>=35 && val<53) do_something;

Actually, yes. You're missing an 'else'.

That being my [inconsequental in this example] mistake
does not per se make it less useful then the switch(true)

I once saw, in the real world, in a production program, 100 (yes,
literally 100) mutually exclusive cases IF'ed without a single ELSE.

Don't be so quick to rule out the possibility that you lack the
experience to understand why the request is reasonable. That's
a really good way to make yourself appear to be spectacularly
ignorant.

Insulting people for making a request whose value you fail to
understand makes you look that much worse.

With the consequence, which probably does need to be spelt out, that the
regular experts will ignore the questions of such posters, confining
themselves to correcting the errors that they make in their responses,
if any, to others.

Whatever suits the convenience of the expert regulars increases the
chances of getting good answers.
