Yes, we can use a range of values with switch case statement ; in this article we are going to discuss the same. For example, if you want to execute same set of statements with a range of numbers, you do not need to write separate case values, you can use range like min_value … max_value.

That is, they must be valid integer constant expressions (C standard 6.8. 4.2). Case ranges and case labels can be freely intermixed, and multiple case ranges can be specified within a switch statement .
Read moreDoes return break a switch case?
Yes, you can use return instead of break … break is optional and is used to prevent “falling” through all the other case statements. So return can be used in a similar fashion, as return ends the function execution.
Read moreHow do you end a switch case?
You can use the break statement to end processing of a particular labeled statement within the switch statement. It branches to the end of the switch statement. Without break , the program continues to the next labeled statement, executing the statements until a break or the end of the statement is reached.

Advertisements. A switch statement allows a variable to be tested for equality against a list of values. Each value is called a case , and the variable being switched on is checked for each switch case.
Read moreWhat is a switch case explain with example?
switch( expression ) { case value-1: Block-1; Break; case value-2: Block-2; Break; case value-n: Block-n; Break; default: Block-1; Break; } Statement-x; The expression can be integer expression or a character expression . Value-1, 2, n are case labels which are used to identify each case individually.
Read moreWhy do we switch case?
The main reasons for using a switch include improving clarity , by reducing otherwise repetitive coding, and (if the heuristics permit) also offering the potential for faster execution through easier compiler optimization in many cases.
