Wrong output

i have code like this
#include
#include <stdio.h>
using namespace std;
int i,n,x,y;
int j[]={};
int main() {
cin>>n;

for(i = 0; i<n;i++){
	cin>>x>>y;
	cout<<x*y<<endl;
	}
}

this program only multiplies input I have run it in the codeblock but why is it still dated incorrectly in spoj
