Hi Praveen,

I tried your code and it will displaying empty as the result because inside the loop you are using ReadLine(). That mean's you want to enter some input but you will get always "-1" as output.

Code :
using System;

public class Program
{
    public static void Main()
    {
        int i = -1;
        for (; Convert.ToBoolean(Convert.ToBoolean(i)); Console.WriteLine(i))
        {
            Console.ReadLine();
        }
    }
}

Hi.
The Code Contains lots of error. When i rectified the code looks like this,
static void Main(string[] args)
{
int i = -1;
for (; Convert.ToBoolean(Convert.ToBoolean(i));Console.WriteLine(i))
{
Console.ReadLine();
}
}

And When i ran the code nothing shows but when i press enter it is displaying -1 and as much time i press enter, that much time it will display -1.
Thanks.
