析构函数

#include <iostream>
using namespace std;
class BASE
{
private:
    int c;
public:
    BASE(int n):c(n) {}
    virtual ~BASE()
    {
        cout<<c;
    }
};
class DERIVED:public BASE

{
private:
    int c;
public:
    DERIVED(int n):BASE(n+1),c(n) {}
    ~DERIVED()
    {
        cout<<c<<endl;
    }
};
class TYU:public DERIVED
{
private:
        int c;
public:
   TYU(int n):DERIVED( n+1),c(n){}
       ~TYU()
       {
       cout<<c<<endl;
       }
};

int main()
{
   TYU t(12);
    return 0;
}

运行结果：

说说:自己感觉好像对析构函数又加深了印象
