C# bool keyword

In C#, bool is a keyword which is used to declare a variable that can store Boolean values true or false. bool keyword is an alias of System.Boolean.

It occupies 1 byte (8 bits) in the memory.

Syntax:

    bool variable_name = value;

There are only two possible values that can be assigned to a bool variable 1) true or 2) false

C# code to demonstrate example of bool keyword

Here, we are declaring a bool variable answer, initializing it with the value true and printing its value, type, and size of a bool type variable.

using System;
using System.Text;

namespace Test
{
    class Program
    {
        static void Main(string[] args)
        {
            //bool variable declaration
            bool answer = true;

            //printing value
            Console.WriteLine("answer: " + answer);
            //printing type of variable
            Console.WriteLine("Type of answer: " + answer.GetType());
            //printing size of a bool 
            Console.WriteLine("Size of a bool variable: " + sizeof(bool));

            //hit ENTER to exit
            Console.ReadLine();
        }
    }
}

Output

answer: True
Type of answer: System.Boolean
Size of a bool variable: 1
