My issue

My code

#include <iostream>
#include <string>
using namespace std;

// define
# define ll long long
# define pb push_back

# define YES cout << "YES" << endl;

# define endl '\n'
# define modulo % (1000000007) //const ll Modulo = 1e9+7;

# define cinarr(arr,n) for(auto i = 0 ; i < n ; i++) cin >> arr[i]; 
# define cinvec(v,n) for(auto i = 0; i < n; i++) {int temp; cin >> temp; v.pb(temp);}

//--------------------------------------------

int main() {
    
	ll d;
    cin >> d;
    if ((d & 1) == 1) cout << -1 << endl;
    else{
        cout << 0 << " " << d << endl;
        cout << d << " " << 0 << endl;
        cout << 0 << " " << -d << endl;
        cout << -d << " " << 0 << endl;
    }
