how is that output possible? ( from a challenge )
int count=1 for (i=1;i<=99;i++) { for (j=1;j<=99;j++) { count++ } cout<<count; } output : 10001

what do you think it should be?

This is just a game, my friend not the art of survival in the wood!
So don't worry about that too much since we are human and humans make a lot of dumb mistakes. Enjoy your time. ;)

Jay is always good at robbing at the right time! So, don't rush. :D

100 * 100 + 1 = 10001
Look jay's code

@ Babak Sheykhan (PERS), a good example 😉

@ jay, thanks for your good explanation 😉

Fyi for anyone else reading.
For each outer loop, the inner loop counts to 100.
Basically it performs a 100 timetable.
1 - 100
2 - 200
etc,
Since the variable we are storing the sum/result in is initially 1, at the end off outer loop the final result has an extra 1. So instead of being 10,000 it is 10,001

You got there though! ok I rob you next time 😀

Oh there was stuff wrong as it was presented in your question.
If that how it was presented in the quiz I would report it.
But yeah. It is (when corrected) pretty straight forward when you analyse the code.
Thus I did not want to rob you of the satisfaction of figuring it out for yourself.
This feeling, in my opinion, is pretty good!

The code is wrong.
if it worked as is it would be 9802
If you see this again code again in challenges. report it

^ exactly.. it should not have been approved.
Questions are submitted and voted upon by the community. As a result some bad questions slip through. Unfortunately this happens.

finally i got it. nothing is wrong with this particular code. i just got stucked. shit happends. i hope for questions without mistakes if possible. thank you both..
+ 1
thanks for the answer but i still dont get it. output answer is 10001 when yours starts with 1001
secondly in a challenge is possible the answer not to be full only covering 5 digits?
+ 1
if the code is wrong how it is included in the challenge with that result?
+ 1
oh please rob me! i would say the monent i asked .. i had stucked for long and tired.. anyway jay.. you are right to your basic point..

haha! funny like your pic..

shit! maby we need more people/questions in the community(so that more choices for the authority of app) or the good ones give more questions or voting allowd only for premium members
