关于访问成员的问题?

#include<iostream>
using namespace std;

class newclass{
  public:
     newclass(int i,int j)
     {
       ii=i;
       jj=j;
     }
     void print();
   private:
     int ii,jj;              
};

void newclass::print()
{
  cout<<ii<<endl<<jj<<endl;
}

int main()
{
  newclass var[2]={newclass(1,2),newclass(3,4)};
  newclass *pi=&var[1];
  cout<<pi->print()<<endl; //不知道为什么出错?
  pi=&var[2];
  cout<<pi->print()<<endl;
  return 0;
}
