Hello,
This is more of a general programming question than a CCS specific question. Hence it would be recommended to check your general 'C' references.

There are also a lot of information on the web:

Thanks

I did at search on Google and found this link:

http://stackoverflow.com/questions/160930/how-do-i-check-if-an-integer-is-even-or-odd

I tried running a slightly modified version of that on a F28069 and it works fine.

what are "odd" and "even"? If they are Boolean flags you need to reset them at the top:
odd = false;
even = false;

and change your naked "even" and "odd" to
even = true;
//..
odd = true;

I usually use "&1" to replace (%2).

if (a&1) {

   // odd

} else {

   // even

}

The efficiency should be better to use "&1".
