WA in ADDREV

[gauravbgkp]

HI, I don't know why I am getting WA, for my ADDREV solution, even after I have run it successfully on my PC. My source is...

include

int reverseDigit(int);
int main(){
int n,a,b,sum;
scanf("%d",&n);
while(n){
scanf("%d%d",&a,&b);
a=reverseDigit(a);
b=reverseDigit(b);
sum=a+b;
sum=reverseDigit(sum);
printf("%d\n",sum);
n--;
}
return 0;
}

int reverseDigit(int x){
int q,rev=0;
for(int i=1;i<=5;i++){
q=x%10;
x=x/10;
rev=(rev*10)+q;
if(x==0){break;}
}
return rev;
}

Please help!
Thanks.

for(int i=1;i<=5;i++)
This means you would get WA for any numbers longer than 5 digits?

Thanks
I actually have done for integer inputs, as mentioned in the question, and integers can range upto a maximum of 5 digits

[hodobox]

integers go up to 2^31-1 = 2,147,486,647. That is more than 5 digits

Integers go up to infinity. The word integer should not be mixed up with the integer data type. Within this problem statement I believe it is meant as a mathematical term.
And, btw, it is all written down here in the forum, e.g http://discuss.spoj.com/t/problem-with-addrev/13893/4?u=daft_wullie

It wasn't specified that the integers fit into 'integer data type', but in this case they do. They go above 5 digits though

Sorry for stressing this point, but even in c/cpp languages the size of integer data type can differ, it is to some degree an implementation detail. As far as I know, guaranteed is only 16bits, but nearly all systems will use at least 32bits.
Other languages support arbitrary large integers, e.g. Python.
