问题描述:
(2)阅读程序,写出执行结果
#include <iostream> using namespace std; class A { public: A(char *s) { cout<<s<<endl; } }; class B:public A { public: B(char *s1, char *s2):A(s1) { cout<<s2<<endl; } }; class C:public A { public: C(char *s1,char *s2):A(s1) { cout<<s2<<endl; } }; class D:public B, C { public: D(char *s1,char *s2,char *s3,char *s4):B(s1,s2),C(s3,s4) { cout<<s4<<endl; } }; int main() { D d("class A","class B","class C","class D"); return 0; }
预计运行结果:
class A
class B
class C
class D
class D
实际运行结果:
