C++类与对象编程的问题，求大神
1、定义一个学生类(Cstudent)，其中数据成员有学号、姓名、年龄，数学，外语，计算机课程的成绩，以及若干成员函数。同时编写主函数使用这个类，实现对学生数据的赋值和输出。
要求：
（1）使用构造函数完成数据的输入；
（2）使用成员函数print()实现数据的输出；
（3）编写主函数，定义对象数组，完成相应功能；
（4）编写函数search(int n),以学号n为参数，在数组中查找学号是n的学生，并返回该生的全部信息。
#include <iostream>
using namespace std;
#define m 3 //输入几个同学信息来着
class Cstudent
{
public:
int xuehao;
char name[100];
int age;
int ShuAchievement;
int WaiAchievement;
int JiAchievement;
Cstudent()
{
cout<<"请输入姓名、学号，年龄，数学，外语，计算机课程（以回车分割）："<<endl;
cin>>name;//先输入的姓名来着
cin.sync();//去除输入缓存
cin>>xuehao>>age>>ShuAchievement>>WaiAchievement>>JiAchievement;
}
void print()
{
cout<<"学号:"<<xuehao<<endl;
cout<<"姓名:"<<name<<endl;
cout<<"年龄:"<<age<<endl;
cout<<"数学:"<<ShuAchievement<<endl;
cout<<"外语:"<<WaiAchievement<<endl;
cout<<"计算机课程:"<<JiAchievement<<endl<<endl;
}
};
int search(int n,int d)
{
if(n==d){return d;}
else {return 0;}
}
void main ()
{
Cstudent a[m];
int d[m];
for(int y=m;y>0;y--){a[y-1].print();d[y-1]=a[y-1].xuehao;}
int n;cout<<"请输入学号："<<endl;cin>>n;
int z=m-1;int p=0;
for(z;z>=0;z--)
{
if(z<m&&search(n,d[z])==d[z]){a[z].print();p++;}
}
if (p==0)
{cout<<"学号输入错误..请重来！"<<endl;;}
}
using namespace std;
#define m 3 //输入几个同学信息来着
class Cstudent

else {return 0;}
}

int z=m-1;int p=0;
for(z;z>=0;z--)
{
if(z<m&&search(n,d[z])==d[z]){a[z].print();p++;}
}
if (p==0)
{cout<<"学号输入错误..请重来！"<<endl;;}
