# Need Karma Points

Wait, what?

You asked a Q stating that you need karma to ask a Q? Am I missing something?

EDIT- And whats this “converted to Q X mins ago” thing? Can anyone explain about that? I would appreciate it!

How did you manage to ask question if you didn’t have karma points ?
Is this 'cause of new system ? (bug or something)

You probably tried too hard on the March challenge and now you seem confused lol.

I think he posted that (the current question) as an answer and someone upvoted him. 1 Hour ago he clicked on convert answer to question and hence the result

So this is the question for which you needed karma points. This should be marked as community wiki

how do i gain karma points to ask question ?
maybe if someone sees this please solve this.
the question is from beginners section FLOW007 - reversing the number.
the code goes:

#include<stdio.h>
#include<math.h>
int main()
{
int t,num,temp,n,i,j,sum;
scanf("%d",&t);// no of test cases
while(t>0){
temp=num;
n=0;
while(temp>0){
temp=temp/10;
n++;// counting no of digits in the number given
}
int a[n];
sum=0;
for(i=0;i<n;i++){
a[i]=num%10;// storing each digit in an array cell
num=num/10;
sum=sum + a[i]*pow(10,(n-(1+i)));//summing by expanding

``````}
printf("%d\n",sum);
``````

t–;
}return 0;
}

i am getting correct reversed number for all numbers except 3-digit numbers.
thanks

What are you saying? Your code passed all test cases. Copy-paste it and try again. See here.

i don’t have sufficient karmas to ask any question… please upvote .

Do we really need more than 3 karma points to ask a question. Why not solving the problems should be criteria.

Anyone here needs karma point!

@swarazoid

replace your sum line code with the following line sum=sum + a[i]*(float)pow(10,(n-(1+i))); . Now your code will work fine.
