关于c++中类的继承与派生
#include<iostream>using namespace std;class A{public: int x; A(int a,int b){ a=x; b=u;} void prt(){ cout<<cout<<x<<endl;}private:int u;};class B:public A{public:B(int a,int b,int c): A(a,b){ y=c;} int y; void prt(){ cout<<"A::x=:"<<A::x<<endl; A::prt(); cout<<" B::y=:"<<B::y<<endl; } };int main(){B b(1,2,3);b.prt();cout<<b.x<<endl;}
