Solution

using System;
public class Binary
{
public static void Main()
{   
string result;
string text;

do 
{
Console.Write("Number to convert: ");
text = Console.ReadLine();

if (text != "end")
{
int n = Convert.ToInt32( text );
result = "";

while (n > 1)
{
result = Convert.ToString( n % 2 ) + result;
n /= 2;
}

result = Convert.ToString(n) + result;
Console.WriteLine("Binary: {0}", result);         }
}
while (text != "end");    
}
}
