Switch range

Question

Can we include ranges in switch cases ? If yes what is the syntax ?

Answer 1

It's not standard C++, but some compilers allow it as an extension. The syntax is

case lower ... upper:

where "lower" and "upper" are both included in the range.
Keep in mind this is not standard, so if portability is a factor, you should probably not include it in your code.

Answer 2

It does work here in the SoloLearn playground, FYI. Here's an example.

For more portability you can take advantage of the switch case fallthrough and list multiple cases consecutively without using a break statement for those ranges. Although this can become cumbersome if you have a large range.
