Cases in a switch statement can have ranges (there must be space around the `...` though). It is supported by GCC and Clang.

case_range.c

#include <stdio.h>

int
main(int argc, char **argv) {
	int i = 0; 
	switch(i) {
		case 0 ... 10:
			printf("0 through 10\n");
			break;
		default:
			printf("not 0 through 10\n");
			break;
	}
	return 0;
}
