What is the purpose of the default case in a switch statement?
a) To handle cases not matched by any other case
b) To terminate the loop
c) To allocate memory dynamically
d) To return a value from a function
Answer:
a) To handle cases not matched by any other case
Explanation:
The default case in a switch statement is used to handle any values that do not match any of the explicit cases. It acts as a catch-all for unhandled conditions, ensuring that the program has a defined behavior even when an unexpected value is encountered. The default case is optional, but it is considered good practice to include it, especially in situations where all possible values of the expression are not known in advance.
Understanding the default case is important for creating robust switch statements that can handle unexpected input gracefully.
