You're reading past the end of a string.

A string is terminated with a null character. Your code continues to read beyond that into uninitialized data.

My code
Code: Select all
#include<stdio.h>
using namespace std;
int main()
{
int t;
scanf("%d",&t);
while(t--)
{
long long x,rev_x=0,y,rev_y=0,sum,rev_sum=0;
scanf("%d %d",&x,&y);
while(x>0)
{
rev_x *= 10;
rev_x += x%10;
x=x/10;
}
while(y>0)
{
rev_y *= 10;
rev_y += y%10;
y=y/10;
}
sum=rev_x+rev_y;
while(sum>0)
{
rev_sum *= 10;
rev_sum += sum%10;
sum=sum/10;
}
printf("%d\n",rev_sum);
}
return 0;
}

First, consider using the code tags to share your code to make it more readable. Think about it: Would you spend even a moment looking at what you posted above as an objective reviewer?
Next, try searching the forums more extensively before you post. Here's a much more detailed thread with test cases and discussion.
http://acm.uva.es/board/viewtopic.php?f ... &hilit=713
Test your code with test cases given there.
