Running in my computer is OK,use use Visual C++ 2010. But in here (use Visual C++ 2013) is wrong answer. I don't understand. Help me, please!

#include <iostream>
using namespace std;

int main(){
        int a[100][100];
        int n, x=0;
        cout<<"\Input n: ";
        cin>>n;
        for(int j=n-1,i=0;j>=0;j--){
            int h=i,k=j;
            while(k<n) a[h++][k++]=++x;
        }
        for(int i=1,j=0;i<n;i++){
            int h=i,k=j;
            while(h<n) a[h++][k++]=++x;
        }
        for(int i=0; i<n ;i++){
            for(int j=0; j<n ;j++){
                cout.width(4);
                cout<<a[i][j];
            }
            cout<<endl;
        }

    cin.ignore(80,'\n');
    cin.get();
    return 0;
}
