I've tried, but the results are "0x28ff18".. that's not "0x29fee8".

Question

or is that code are representing a same thing? representing "5" ?

Answer 1

Both of those codes are memory addresses. Whatever variable you're pointing to could be at any location in memory, you'll rarely see the same one twice.
Those addresses don't say anything about what it holds.

Answer 2

Thanks a lot. Thank you Tamra for your help ..
