Is this c/c++ code valid

[Hamid Taebi]

Is this a real question? or you are new to c++?

:) Thanks for the reply. Please post your choice.

I'm not new to C++ :omg: . Today I had to write some code which includes swith cases, but case lables are valid in only some conditions (depending on the device type). I was not completly sure that the code is invalid, and wrote a test pgm in vs2k3, and it worked fine. Before checking in, wanted a confirmation.

and the reason behind this doubt for not using an 'if' in a switch block is ... :doh: !!! :-D

Yes. But compile the following code and you'll know how much the compiler 'cares' about the IF statement.

int i=4;
switch(i)
{
  if(false) //Whaaa?!
  {
     case 4:
	AfxMessageBox("Whack my head with that oldskool keyboard");
            break;
  }
}

Is it the encrypted version of some nice piece of code? :) BTW on my system (VS2005) it compiles, but at runtime the switch condition overrides (breaks :rolleyes:) the if one: is it what you're expecting?

Rutherford would say: "the switch statement targets its case condition passing the if block like as if you fired a 15-inch shell at a piece of tissue paper" :laugh:

yeah, it was encrypted with 128bit RSA algo. Its great that you could decrypt it :) .Just kidding.. Its neither encrypted nor a question from an interview. I had to write some code today and I re written the code in different way also. But I gor a doubt if this code is valid and wanted a confirmation.

[CPallini]

The code compiles. But I doubt it works as you expect (i.e. avoid such misleading constructs). :)

Why would you go to all the trouble of creating this post when you could have just compiled it to find out? :rolleyes:
