What happens if the value of a variable doesn't match any of the cases in a CASE statement, and there is no default clause?
The first case is automatically executed.
An error occurs and the program terminates.
The program continues to the next statement after the CASE block.
The program will go into an infinite loop.
Explanation
If no case matches and no default, execution proceeds to the statement after the CASE block.
