random_num(0, 30)

how can i do that ? don't consider 13 and 22 number
Thanks

 do (a = random_num(0, 30))
while (a == 13 || a == 22);

Does this helps?

No its a bad code
And might cause infinite loop causing a crash...

Fill out the numbers you want into an array then do a random taking array size as parameter in the random operation

The chance of that happening in that span with so few exceptions is so small that it's not even worth caring about.

Why preferring to chooses a method that it has a chance of error over a fixed one.

You have to concider the probability of this.

Randomizing a temporary filename with 6 characters, assuming we use all lowercase, uppercase and numeric characters and want to avoid an infinite loop we would end up with 26+26+10 different characters ^6, therefor 56 800 235 584 different options. Saving those in an array of 7 cells each since you need to null-terminate that's 1.45Terabyte of memory.
Would you use the same method of generating it? No you wouldn't because it's illogical. You would waste more power preparing the array then using it.

You have to draw the line somewhere and if the exceptions are static and the probability to hit them in one cycle is less than 20-30% then the probability for an infinte loop is WAY too low. If you follow the rules of probability you would hit a correct number in 3-4 loop cycles.

By preparing an array in cases they are not required you are actually wasting CPU and memory for no reason than to feel good about yourself.

If the exceptions however are dynamic then I would definitely use an array.

Its dynamic..

But the loop still has a error percentage.

Yeah i would use more memory inorder to avoid the error

Don't rely on random for such things. You can get the same result 10times and it's perfectly fine since it is a random result, it depends on prediction/distribution/concurrency etc
Also a critical part is how random_num it is implemented in amxx(i'm too lazy to search about it), which random engine/generator is used. So you better use what @Natsheh suggested since it is the best and safe/deterministic solution.
