求大神指导 鄙人编了个student类 实现重载、构造函数

#include <iostream.h>
#include <strstrea.h>
namespace Student
{
class Student
{
string id;
string name;
int age;
string Sex;
student::Student(string ID,string Name,int Age,string Sex)
{
id=ID;
name=Name;
age=Age;
sex=Sex;
}
}
void Main()
{
Student *s1=new Student("陈伟"，"JK114206",",22,"男");
cout<<"学号 "<< s1.ID<<"姓名："<<s1.Name<<"年龄"<<s1.Age<<"性别："<<s1.Sex<<endl;
}
