指向学生类的指针

#include <iostream>
using namespace std;
class student
{
   public:
       student(int n,double sc):num(n),score(sc){};
    double getscore();
    int getnum();
    void setscore(double s);

   private:
    int num;
    double score;

};
double student::getscore()
{
    return score;
}
int student::getnum()
{
    return num;
}
void student::setscore(double s)
{
    score=s;
}
int max(student *arr)
{
   int renum=0;
   int i=0;
   int MAX=-1;
   while(i<5)
   {
       if(arr->getscore()>MAX)
       {
          MAX=arr->getscore();
          renum=arr->getnum();
       }
       i++;
       arr++;
   }
return renum;
}
int main()
{
   student stud[5]={student(101,78.5),student(102,85.5),student(103,100),
   student(104,98.5),student(105,95.5)};
   int i=0;
   for(i=0;i<5;i+=2)
   {
       cout<<stud[i].getnum()<<" "<<stud[i].getscore()<<endl;
   }
   cout<<"5个学生中成绩最高者的学号为："<<max(stud);
  return 0;
}

运行结果：

学习心得：好慌好慌，差点忘了构造函数

注：对get set 函数的利用
