| | You should have made a discussion thread not a poll.  |
| | Hello ghostmonkey, In line 19 you didn't assign the value. You have used == . Is that a mistake due to your typing ? Why can't you use another integer array for storing zeros and a variable to count the number of zeros ?  |

| | Hello francis25, consider a set {2,2,2,2,2,2,2}, to find the sum of all elements in the set, you would count the number of 2's and multiply it with 2. You can also add all the 2's instead of multiplying and that's what is done in the code you posted. Variable i … |

| | Hello taumang, Your if statement is missing and i think you might have got the error "Misplaced else" and your while loop will print x infinite times (x=x+1 will not be done at all).[COLOR="black"] cout[/COLOR] is given as [COLOR="black"]cout<<[/COLOR] in c++. |
| | Hello tinee, You have given [COLOR="black"]while(j-1>=0)[/COLOR]. It should have been j>=0 (note that j=j-1 should be given just before the while loop in the main) because every time after decrementing the loop checks j-1>=0(which is like decrementing twice though not decremented actually) and you get only half the values you … |
