显示从键盘插入的多边形坐标

#include <iostream>
using namespace std;

class Polygon {
  private:

     int nrVarfuri, x[10], y[10];

  public:
    Polygon(){}
    Polygon(const Polygon &p){}

    void show()
    {
        cout<<"Number of tips: "<<nrVarfuri<<endl;

        for(int i=1;i<=nrVarfuri;i++){
            cout<<"X ["<<i<<"]="<<x[i]<<endl;
            cout<<"Y ["<<i<<"]="<<y[i]<<endl;
        }
    };
    void setValues (int nrVal, int XO[], int YO[]){
        nrVarfuri = nrVal;
        for(int i=1;i<=nrVal;i++){
            x[i]=XO[i];
            y[i]=YO[i];
        }
    };
};

int main ()
{
    int poly,i,tips,j;
    int x[tips],y[tips];
    cout<<"Insert the number of polygons: "<<endl;cin>>poly;

    Polygon tabPoligon[poly];
    Polygon p;
    for(i=0;i<poly;i++){
       // cout<<"Insert the number of tips: "<<endl; cin>>tips;
        cout<<"Numarul de varfuri: "<<endl; cin>>tips;
        for(j=1;j<=tips;j++)
        {
            cout<<"X["<<j<<"]:";cin>>x[j];
            cout<<"Y["<<j<<"]:";cin>>y[j];
        }
        p.setValues(tips,x,y);
        tabPoligon[i]=p;

    for(int i=0;i<poly;i++){
     cout<<"\n\nThe polygon have the folowing coordinates: "<<endl;

    }
     tabPoligon[i].show();

  }
  return 0;
}

我必须插入数字的数量，从键盘插入坐标并打印它们。程序在从键盘读取坐标后显示坐标，而不是等待插入另一个多边形坐标，这是什么问题？
