Exercise
Classes Student + Teacher
Objetive
Create a new project, and include in it the class Person that you just created.
Create a class "Student" and another class "Teacher", both descendants of "Person".
The class "Student" will have a public method "GoToClasses", which will write on screen "I’m going to class."
The class "Teacher" will have a public method "Explain", which will show on screen "Explanation begins". Also, it will have a private attribute "subject", a string.
The class Person must have a method "SetAge (int n)" which will indicate the value of their age (eg, 20 years old).
The student will have a public method "ShowAge" which will write on the screen "My age is: 20 years old" (or the corresponding number).
You must create another test class called "StudentAndTeacherTest" that will contain "Main" and:
Create a Person and make it say hello
Create a student, set his age to 21, tell him to Greet and display his age
Create a teacher, 30 years old, ask him to say hello and then explain.
Example Code
using System;
namespace December_19th
{
class Teacher : Person
{
private string subject;
public void Explain()
{
Console.WriteLine("Explanation begins");
}
}
}
using System;
namespace December_19th
{
class StudentAndTeacherTest
{
static void Main()
{
bool debug = false;
//Create a Person and make it say hello
Person myPerson = new Person();
myPerson.Greet();
/*Create a student, set his age to 21,
tell him to Greet and display his age*/
Student myStudent = new Student();
myStudent.SetAge(21);
myStudent.Greet();
myStudent.ShowAge();
/*Create a teacher, 30 years old,
*ask him to say hello and then explain*/
Teacher myTeacher = new Teacher();
myTeacher.SetAge(30);
myTeacher.Greet();
myTeacher.Explain();
if (debug)
Console.ReadLine();
}
}
}
using System;
namespace December_19th
{
class Student : Person
{
public void ShowAge()
{
Console.WriteLine("My age is: {0} years old", age);
}
}
}
using System;
namespace December_19th
{
class Person
{
protected int age;
public void Greet()
{
Console.WriteLine("Hello");
}
public void SetAge(int n)
{
age = n;
}
}
}
