No, they won't. Without a break statement, the following code *will be
executed* - i.e. *without* testing the subsequent condition.

will output "12". The first condition is tested, and it passes that test
- so the "1" is put into K. Then the code falls through (without testing
whether or not "v=2" and the second code fragment is executed - so the
"2" is put after K
