Thread: What's the best way to write this?

Hi, I'm wondering what the best way to find out if a variable equals one of two or more values is.

for example:

Code:

if (i == 2 || i == 3) {
	do_something();
	do_something_else();
} else {
	do_nothing();
	do_nothing_else();
}

or if you use an inline if:

Code:

(i == 2 || i == 3) ? do_something : do_nothing;

the problem i find with this is that i can never equal both 2 and 3 at the same time, and there's no logical XOR operator in C. so is the following way the correct one?:

Code:

switch(i) {
	case 2:
	case 3:
		do_something();
		do_something_else;
		break;
	default:
		do_nothing();
		do_nothing_else;
		break;
}

or is there a better way to write this?

Well, you could but what i was trying to demonstrate was that an OR where both are true or an AND are useless because it can never evaluate to true. I'm just wondering if the switch statement really is the best way, or if there's a better way to write this. Previously I was using the if(i == 2 || i == 3) method, but now that I think about it it doesn't really seem right for the reason stated above.
