void display()

cout<<"输出:"<<w<<endl;

cout<<"All right!"<<endl;
cout<<"Goodbye!"<<endl;

}};
int main()

Welcome we;
Welcome you(we);
you.display();
you.set("How are you?");
cout<<you.get()<<endl;
you.talk();
you.display();
return 0;

Answer 1

cin>>w; 空格是一个特殊字符，分隔符号，如果想输入空格，建议用引号引起来

如
“How are you”追问

题目要求是直接输入：What's your name?
然后自动输出：What's your name?
输入时不能加双引号的

追答

那么建议采用cin.get(w, 100) 来做

追问

出问题啊
