这就是传说中的智能指针么???

C/C++ code

/***********这就是智能指针么?感觉像计数器***********/class U_ptr{private:    friend class Has;    int *ip;    int plus;    U_ptr(int *p):ip(p), plus(1){}    ~U_ptr() {delete ip;}};class Has{private:    int val;    U_ptr *use;public:    Has(int i, int *p): new U_ptr(p), val(i) {}    Has(const Has &rhs){val = rhs.val; use = rhs.use; ++use->plus;}    ~Has(){if(use->puls == 0) delete use;}};
