 and the

operator, as shown here:

!p | q

The following program demonstrates this implementation:

// Create an implication operator in C#.

using System;

class Implication {

  static void Main() {

    bool p=false, q=false;

    int i, j;

    for(i = 0; i < 2; i++) {

      for(j = 0; j < 2; j++) {

        if(i==0) p = true;

        if(i==1) p = false;

        if(j==0) q = true;

        if(j==1) q = false;

        Console.WriteLine("p is " + p + ", q is " + q);

        if(!p | q) Console.WriteLine(p + " implies " + q +

                    " is " + true);

        Console.WriteLine();

      }

    }

  }

}

The output is shown here:

p is True, q is True

True implies True is True

p is True, q is False
