int n;
Console.WriteLine("Enter a digit: ");
n = Convert.ToInt32( Console.ReadLine() );
Console.Write( n );
Console.Write(" ");
Console.Write( n );
Console.Write(" ");
Console.Write( n );
Console.Write(" ");
Console.Write( n );
Console.WriteLine();
Console.Write( n );
Console.Write( n );
Console.Write( n );
Console.WriteLine( n );
Console.WriteLine();
Console.WriteLine("{0} {0} {0} {0}", n);
Console.WriteLine("{0}{0}{0}{0}", n);
