结构体得运用

#include<iostream>#include<iterator>#include<set>using namespace std;struct student{char name[20];int Grade;int Gradeclass;char leader;char West;int Thesis;int Scholarship;};bool operator<(const student& s1,const student& s2){return s1.Scholarship>s2.Scholarship;}int Count(student &s){ s.Scholarship=0;  if(s.Grade>80&&s.Thesis>=1)  s.Scholarship+=8000;  if(s.Grade>85&&s.Gradeclass>80)  s.Scholarship+=4000;  if(s.Grade>90)  s.Scholarship+=2000;  if(s.Grade>85&&s.West=='Y')      s.Scholarship+=1000;  if(s.Gradeclass>80&&s.leader=='Y')  s.Scholarship+=850;return s.Scholarship;}int main(){int N;cin>>N;while(N--){int num;cin>>num;student s;set<student>group;int Total=0;for(int i=0;i<num;i++){cin>>s.name>>s.Grade>>s.Gradeclass>>s.leader>>s.West>>s.Thesis;  Total+=Count(s);  group.insert(s);}set<student>::iterator it=group.begin();cout<<it->name<<endl<<it->Scholarship<<endl<<Total<<endl;}}

在重载输入流得时候出了问题

//istream&  operator>>(istream&  in,student s)//{//in>>s.name>>s.Grade>>s.Gradeclass>>s.leader>>s.West>>s.Thesis;//return in;//}

＝＝！没加引用。。丢人

#include<iostream>#include<iterator>#include<set>using namespace std;struct student{char name[20];int Grade;int Gradeclass;char leader;char West;int Thesis;int Scholarship;};istream&  operator>>(istream&  in,student &s){in>>s.name>>s.Grade>>s.Gradeclass>>s.leader>>s.West>>s.Thesis;return in;}bool operator<(const student& s1,const student& s2){return s1.Scholarship>s2.Scholarship;}int Count(student &s){ s.Scholarship=0;  if(s.Grade>80&&s.Thesis>=1)  s.Scholarship+=8000;  if(s.Grade>85&&s.Gradeclass>80)  s.Scholarship+=4000;  if(s.Grade>90)  s.Scholarship+=2000;  if(s.Grade>85&&s.West=='Y')      s.Scholarship+=1000;  if(s.Gradeclass>80&&s.leader=='Y')  s.Scholarship+=850;return s.Scholarship;}int main(){int N;cin>>N;while(N--){int num;cin>>num;set<student>group;int Total=0;for(int i=0;i<num;i++){  student s;cin>>s;  Total+=Count(s);  group.insert(s);}set<student>::iterator it=group.begin();cout<<it->name<<endl<<it->Scholarship<<endl<<Total<<endl;}}
