using System; using System.Text;namespace Test {class Program{static void Main(string[] args){//bool variable declarationbool answer = true;//printing valueConsole.WriteLine("answer: " + answer);//printing type of variableConsole.WriteLine("Type of answer: " + answer.GetType());//printing size of a bool Console.WriteLine("Size of a bool variable: " + sizeof(bool));//hit ENTER to exitConsole.ReadLine();}} }Output
