继承的构造和析构顺序

程序示例
 1 #include <iostream>
 2 using namespace std;
 3 class a
 4 {
 5 public:
 6     a(){cout<<"构造a"<<endl;}
 7     ~a(){cout<<"析构a"<<endl;}
 8 };
 9 class b
10 {
11 public:
12     b(){cout<<"构造b"<<endl;}
13     ~b(){cout<<"析构b"<<endl;}
14 };
15 class c
16 {
17 public:
18     c(){cout<<"构造c"<<endl;}
19     ~c(){cout<<"析构c"<<endl;}
20 };
21 class d
22 {
23 public:
24     d(){cout<<"构造d"<<endl;}
25     ~d(){cout<<"析构d"<<endl;}
26 };
27 class e
28 {
29 public:
30     e(){cout<<"构造e"<<endl;}
31     ~e(){cout<<"析构e"<<endl;}
32 };
33 class f:public a,public b,public c,public d,public e//构造和销毁类的顺序与此顺序有关
34 {};
35 void main()
36 {
37     f a;
38 }
