Singer类

Singer类

描述

 

实现一个Singer类，通过以下测试：

int main()
{

Singer s1,s2;
cin>>s1>>s2;
cout<<s1<<"\n"<<s2<<endl;

if(s1>s2)
cout<<s1.getName()<<"'s score is higher than "<<s2.getName()<<"'s.\n";
else if(s1==s2)
cout<<s1.getName()<<"'s score is equal to "<<s2.getName()<<"'s.\n";
else
cout<<s1.getName()<<"'s score is lower than "<<s2.getName()<<"'s.\n";

return 0;
}

 

输入

 

输入包含两行，第一行为歌手s1的信息，第二行为歌手s2的信息，每位歌手的信息包括姓名（不包含空格）、性别、年龄 和 分数；姓名、性别、年龄和分数之间用空格分隔

 

输出

 

输出为三行，前两行分别是歌手s1和s2的信息，第三行根据s1和s2比较结果输出（s1和s2的比较结果和他们的分数的比较结果一致），具体参见主函数

 

输入样例 1 

Mary F 28 99.5
Peter M 26 98

输出样例 1

Mary F 28 99.5
Peter M 26 98
Mary's score is higher than Peter's.
