Answer 1

#include <iostream>
#include <string>
using namespace std;
class student
{
public:
student()
{
}
student(char *id,char *name,int age)
{
strcpy(stuId,id);
strcpy(stuName,name);
stuAge = age;
}
void display()
{
cout<<"学号:"<<stuId<<"姓名:"<<stuName<<"年龄:"<<stuAge<<endl;
}
private:
char stuId[10];
char stuName[20];
int stuAge;
};
int main()
{
student st("001","yingxing",10);
st.display();
return 0;
}

Answer 2

#include <iostream>
#include <string>
using namespace std;

class Student
{
char Id[20];
char Name[20];
int Age;
public:
Student(char Id[20],char Name[20], int Age);
void Display();
};

Student::Student(char* _id,char* _name, int _age)
{
strcpy(Id, _id);
strcpy(Name, _name);
Age = _age;
}

void Student::Display()
{
cout << "学号：" << Id << " 姓名：" << Name << " 年龄：" << Age;

}

int main()
{
Student stu("001","yingxing", 10);
stu.Display();
return 0;
}

Answer 3

#include <iostream>
usingnamespacestd;
class Student{
private:
string id;
int age;
string name;
public:
Student(string vid, string vname, int vage)
{
id = vid;
name = vname;
age = vage;
}
void display()
{
cout << "my name is "<<name << ",my age is " << age << endl;
}
};
int main (int argc, constchar * argv[])
{

// insert code here...
Student *student = newStudent("001", "yingxing", 10);
student->display();
return0;
}
