Question

A case can be labeled as _________ to execute in the event that none of the provided cases are equivalent to the controlling expression.

A) General
B) Default
C) Case *
D) None of the above.

Answer 1

A case labeled as 'Default' is used in a switch statement when no other cases match the controlling expression. It is a common feature in many programming languages to handle unexpected cases.

Step-by-step explanation:

A case can be labeled as Default to execute in the event that none of the provided cases are equivalent to the controlling expression. In programming languages that utilize switch statements, such as C, C++, Java, and JavaScript, the default case is a catch-all option that executes when no other case matches. It is important in providing a fallback scenario and ensuring that the switch statement can handle unexpected or undefined case values.
