Requirements

In programming, you often work with logical values, which are the values of "yes" and "no." or true false.

Hint

The type for logical values is called bool in C#.

The value "yes" is written as true, and the value "no" is written as false.

Demo

using System;

class Program/*from   ww  w .  java  2 s.c o m*/
{
    static void Main(string[] args)
    {
        // Two logical (Boolean) variables 
        bool goingToRain = true;
        bool iAmHungry = false;

        // Use exclamation mark to negate logical value 
        bool iAmNotHungry = !iAmHungry;

        // Output 
        Console.WriteLine("She loves me: " + goingToRain);
        Console.WriteLine("I am hungry: " + iAmHungry);
        Console.WriteLine("I am not hungry: " + iAmNotHungry);

    }
}

Result

You can use an exclamation mark to negate a logical value (to flip it from "yes" to "no" and back again).
