what happens when case has no content

what happens in the following case

Code:

---

switch(somechar)
{
    ...
    ....
    case '=' :
  case 'D' ://do something
            break;
 }

---

will case 'D" also be entered when the character is "=" ??

Yes.

It enters the next case because there is no "break" at the end of it, not because it has no content.

Code:

---

switch ( x )
{
  case 1:
      func1();
  case 2:
      func2();
};

---

if x is 1 it will do func1() and func2(), if x is 2 it will do only func2().

thanks folks.
