Can anyone help? I\'m trying to solve problem as my code is working fine on my complier but doens\'t work on codecon.. as stated segmentation fault or something I have my code here .. thanks. I think you can go to codecon and look at the questions..

Solution

Change this declaration of variables

char X[]=\"\";
   char Y[]=\"\";

to

char X[70];
   char Y[70];

X and Y will maximum hold 70 characters . long long value should be able to fit in that.

You should be gettng segmentation error because initalially x and y have less memory 1 character for null terminator but later when user inputs values, it occupies bigger space. So change the declarations as mentioned above and the problem should be resolved. Please do comment/rate the answer if problem is resolved thanks.
