What is the result of executing a switch statement without a default case?

Executing a switch statement without a default case allows the program to function normally, but it means that if none of the specified cases match the expression being evaluated, then no specific actions will be taken for that switch statement. In this situation, the control simply moves to the code following the switch statement, which may lead to no output or actions being performed if there are no further instructions.

This behavior is important for understanding how control flow works in programming. The absence of a default case means there is no catch-all action to be taken if no matches are found, which is why nothing will execute if there are no matching cases.
