双引号用英文符
#include<iostream>
using namespace std;
class A
{
    int num;
public:
    A()
{num=0;cout<<"A default constructor"<<endl;}
    A(int n)
{num=n;cout<<"A constructor,num="<<num<<endl;}
    ~A()
{cout<<"A destructor,num="<<num<<endl;}
};
void main()
{
    A a,*p;
    p=new A(2);
    a=*p;
    delete p;
    cout<<"Exiting main"<<endl;
}
