thanks for the code!
ReplyDeletecan you just explain it to me roughly
Using "temp=num%10;" we got the remainder i.e. last digit of number "num". Then we added it to "sum" ("sum" is 0 at starting) using "sum+=temp;". Now we will remove last digit of number by "num=num/10;" . We will repeat this until "num" is 0.
DeleteHope you understood. If you have any doubt please feel free to ask.
