Question

What is the purpose of default clause in a switch statement?

Answer 2

Purpose of default clause in a switch statement:

Default clause in switch statement works as the same as else clause in if else block. If any of the other case values of the switch statement is not true, the default case will be activated. A switch is a multiple-way statement that gives a simple way to send execution to various parts of codes based on the expression values.

If anything is not matched in a switch statement then nothing could be done without the value default case. In a switch case, it is the exact significance of the default case.
