Program to illustrate 'const' keyword

The const keyword is used to modify a declaration of a field or local variable. It specifies that the value of the field or the local variable cannot be modified.

// program to illustrate const keyword
// using  c#

using System;

public class ConstTest
{
    class MyClass
    {
        public int x;
        public int y;
        public const int c1 = 5;
        public const int c2 = c1 + 5;
       
        public  MyClass(int p1, int p2)
        {
            x = p1;
            y = p2;
        }
    }
   
    public static void Main()
    {
        MyClass mC = new MyClass(11, 22);
        Console.WriteLine ("x = {0}, y = {1}", mC.x, mC.y);
        Console.WriteLine ("c1 = {0}, c2 = {1}", MyClass.c1, MyClass.c2);
    }
}

OUTPUT:
x = 11, y = 22
c1 = 5, c2 = 10
