函数max用指向对象的指针作函数参数

#include <iostream>using namespace std;class Student{public:Student(int n,int s):num(n),score(s){};void display();int num;int score;};void Student::display(){cout<<num<<":"<<score<<endl;}int main(){void max(Student *);Student stud[5]={Student(1011,84),Student(1012,97),Student(1013,78),Student(1014,83),Student(1015,88)};Student *p=stud;//使指针指向数组的首元素for(int i=0;i<3;p+=2,i++){cout<<(i+1)<<" ";p->display();//stud[i].display}Student *p1=stud;    max(p1);return 0;}void max(Student *stu){int max_score=0;int k;//存储最大值的角标for(int j=0;j<5;j++)//求最大值if(max_score<stu[j].score){max_score=stu[j].score;k=j;}cout<<"The max score is "<<stu[k].score<<",its number is "<<stu[k].num<<endl;}
