C++ Case/Switch Statement Warning


If you are a programmer of any kind, you are most likely familiar with the Case/Switch statement.  This is simply a way in programming for you to do different things depending on the value of a variable.  For example..if your working with a variable named abc.  You might want to do different things depending on what the value is.  The long way would be to put down a long if/else statement to deal with each potential value type.  The easy way is to use a simple switch/case statement.  No matter what language you are using, this will come into play at some point.

If you are using PHP a switch/case statement might look like follows:

$variable = 'test';
switch($variable) {
  case 'test':
  // do something
  break;
case 'test2':
  // do something
  break;
case'test3';
  // do something
  break;
}
?>

That is very simple.  It’s quite similar to JavaScript, but with a little different syntax.  Now here is the tricky part.  I don’t know every language out there. However, quite a few of them have the same type of structure of Switch/Case statements.  Then suddenly C++ throws you a loophole.  In working with C++ it’s just about the same as PHP.  Except for one strange thing. If you initialize a variable inside of a switch/case statement you have to use brackets around each interior case when you are initializing a variable. Just something tricky that I had to figure out with a lot of trial and error.
