 4 class Base {
 5 public:

 7     Base(int n):k(n) { }
 8 };
 9 class Big
10 {
11 public:
12     int v;
13     Base b;
14  Big(int i = 0):v(i),b(i){}
15     Big(const Big& a):v(a.v),b(a.b.k){}
16 };
17 int main()

20     while(cin >>n) {
21         Big a1(n);
22         Big a2 = a1;
23         cout << a1.v << "," << a1.b.k << endl;
24         cout << a2.v << "," << a2.b.k << endl;
