complilation error can be also achieved by calling division by zero, falling out of arrays, etc. the test may contain some situation which your program can't handle validly.

I think it is because of the header you are using.
I think it must be written like this :

#include <fstream>
using namespace std;

You can't write
for (int x = 1; x <= n; x++) {...}
and then
for (x = 2; x <= n; x++) {...}
x is underfined here!

you should write
int x;
for (x = 1; x <= n; x++) {...}
for (x = 2; x <= n; x++) {...}
or
for (int x = 1; x <= n; x++) {...}
for (int x = 2; x <= n; x++) {...}

what's the meaning,it's too long
