c++中的单继承

#include<iostream>
using namespace std;

class A
{
      public:

             A(int i):a(i){cout<<"调用A";cout<<a<<endl;}
      private:
              int a;

};

class B:public A
{
      public:

             B(int i,int j):A(i),aa(i),b(j){cout<<b<<endl;}
      private:
              A aa;
              int b;
};

class C:public B
{
      public:
             C(int i,int j,int k):B(i,j),bb(i,j),c(k){cout<<c<<endl;}

      private:
              B bb;
              int c;

};
int main()
{
    C cc(1,2,3);
    system("pause");
    return 0   ;
}

运行结果：
调用A1
调用A1
2
调用A1
调用A1
2
3
