#include<iostream>using namespace std;class student{public:student(int n,double s){num=n;score=s;}void showdata(){cout<<"学号："<<num<<endl;cout<<"成绩："<<score<<endl;}friend void max(student *p);private:int num;double score;};void max(student *p){double maxs=p[0].score;int j;for(int i=0;i<6;i++){if(p[i].score>=maxs){maxs=p[i].score,j=i;}}cout<<"最高分："<<maxs<<endl;cout<<"学号："<<p[j].num<<endl;}int main(){student stu[6]={student(1001,99),student(1002,100),student(1003,98),            student(1004,97),student(1005,96),student(1006,95)};student *a=stu;    max(a);return 0;}
