下列程序的输出结果是0，11，12，请将划线处的语句补充完整 #include<iostream.h> Class A｛ Public: A(int aa=0):a (aa)｛｝ Void Print()const｛cout<<a<<‘,’;｝ Private: Int a; ｝; Class B:public A｛ Private: Int b; A c; ｝; Int main()｛ B obj(10); Onj.Print(); Return 0; ｝

Answer 1

#include<iostream> using namespace std; class A{ public: A(int aa=0):a (aa){} void Print()const{cout<<a<<',';} private: int a; }; class B:public A{ public: B(int aa=0):b (++aa),c(++aa){} void Print()const{((A)*this).Print();cout<<b<<',';c.Print();} private: int b; A c; }; int main(){ B obj(10); obj.Print(); return 0; }

Answer 2

#include<iostream>
using namespace std;
class A{
public:
A(int aa=0):a (aa){}
void Print()const{cout<<a<<',';}
private:
int a;
};
class B:public A{
public:
B(int aa):b (aa+1),c(aa+2){}
void Print()const{((A)*this).Print();cout<<b<<',';c.Print();}
private:
int b;
A c;
};
int main(){
B obj(10);
obj.Print();
return 0;
}
