有关指针 -> 和* 的重载

 1， #include<iostream>
    #include<string>
    using namespace std;
    class test{
            int i;
    public:
            test(int i){
                    cout << "test(int i)" << i << endl;
                    this->i = i;
           }
           int get(){
                   return i;
           }
           ~test(){}
   };
   class pointer{
           test* mp;
   public:
           pointer(test*p = NULL){
                   mp = p;//成员变量赋值
           }
           test* operator->(){
                   return mp;
           }
           test& operator*(){
                   return *mp;
           }
          ~pointer(){
                   cout << "~pointer()" << endl;
                   delete mp;
           }
   };
   int main(){
           for(int i=;i<;i++){
                   pointer p = new test(i);
                   cout << p->get() << endl;
           }
           return ;
   }
 //结果
 test(int i)

 ~pointer()
 test(int i)

 ~pointer()
 test(int i)

 ~pointer()
 test(int i)

 ~pointer()
 test(int i)

 ~pointer()
