naveen if you are concerned about challenge question, I am sure that it was not having any issue... I guess you made typo in posting this question.... as far as I recall challenge, it was as below : int a = 0xa; cout << hex << a; answer for above is a only...check in playground if you wish... coming to reason behind this is as below: oxa is not multiplication of 0 and a... it give random value (on playground , it gives 0) as a is not assigned value yet... 0x is used to denote that number is hexadecimal... a in hexadecimal stand for value 10... so do check below in code playground and you will get answer as 10. int variable = 0xa; cout << variable ; if we write hex in between cout (cout << hex << variable;) output is a again as int value of variable which is 10 got converted to hexadecimal value a again...

0 should be... I have never seen code like this "Int a = a*0", its just kind of pointless, huh

naveen well, i just made a cpp code like this and ran it, and it outputed 0. Report the challenge for wrong answer, you can make a cpp code like this and check for yourself if you want to be sure
