//重载,覆盖,隐藏举例 #include <iostream> using namespace std; class A { public: int n; void fun() { cout<<"A::fun()"<<endl; } virtual void fun(int a) { cout<<"A::fun(int)"<<endl; } void fun(double f) { cout<<"A::fun(double)"<<endl; } }; class B:public A { public: int n; void fun(int a) { cout<<"B::fun(int)"<<endl; } void fun(double f) { cout<<"B::fun(double)"<<endl; } }; int main(int argc, char *argv[]) { A a; B b; A *p; p=&b; p->fun(); p->fun(20); p->fun(19.9); b.fun(19.9); b.n=5; cout<<b.A::n<<endl; return 0; }
