When compared to a complex or layered series of if else statements, switch statements have a clearer syntax. Instead of if, when, use switch: You're comparing numerous possible expression circumstances, and the expression itself isn't simple.
The following is a general syntax for how switch-case is implemented in a 'C' programme: case value-1: Block-1; Break; case value-2: Block-2; Break; case value-n: Block-n; Break; default: Block-1; Break; case value-3: Block-3; Break; Statement-x; An numerical expression or a character expression can be used.
No, default case is not required in a switch statement, and there is no restriction that it must be placed at the conclusion of all cases; it can be placed at the beginning or in the middle of the others.
The switch statement examines an expression and executes statements connected with that case, as well as statements in case s that follow the matched case.
