Boolean represents just two values, i.e. True or False.
A bool Data Type can accept only true or false.
public class MyApplication
{
public static void Main(string[] args)
{
bool x = true;
bool y = false;
System.Console.WriteLine(x);
System.Console.WriteLine(y);
}
}
So, in the above code, we have created a variable named x of Boolean data type and initialised it with value True.
bool x = true;

And created one more variable called y of Boolean data type and initialised it with value False.
bool y = false;

But if we want to initialise a Boolean type variable with anything other than true/false, it would end up with an error.
