C++对象两种方法的声明

//正确的姿势：
PointToPointHelper * ptrP2P[2];
for (int iAggNode=0;iAggNode<2;iAggNode++)
{
PointToPointHelper * pointToPoint=new PointToPointHelper() ;
ptrP2P[iAggNode]=pointToPoint;
}
ptrP2P[1]->EnablePcapAll ("InRoot");
for(int i=0;i<2;i++)
{
delete ptrP2P[i];
}

//错误的姿势:
//在for循环中使用
PointToPointHelper pointToPoint;
ptrP2P[iAggNode]=&pointToPoint;
//当for循环退出时，该对象被销毁，所以会出现访问未知地址错误
