7.18.1.Demonstrate protected.
  1. A protected member is public within a class hierarchy, but private outside that hierarchy.
  2. A protected member is created by using the protected access modifier.
using System; 
 
class BaseClass 
  protected int i, j; // private to BaseClass, but accessible by D 
 
  public void set(int a, int b) { 
    i = a; 
    j = b; 
  
 
  public void show() { 
    Console.WriteLine(i + " " + j)
 

 
class DerivedClass : BaseClass 
  int k; // private 
 
  // DerivedClass can access BaseClass's i and j 
  public void setk() { 
     k = i * j; 
  
 
  public void showk() { 
    Console.WriteLine(k)
  

 
class MainClass 
  public static void Main() { 
    DerivedClass ob = new DerivedClass()
 
    ob.set(23)// OK, known to DerivedClass 
    ob.show();    // OK, known to DerivedClass 
 
    ob.setk();  // OK, part of DerivedClass 
    ob.showk()// OK, part of DerivedClass
