        // Initialize a string object
        string str = "The Sun rises in the East,sets in the West.";
  
        // Instantiate a CharEnumerator object
        CharEnumerator chEnum = str.GetEnumerator();
  
        while (chEnum.MoveNext()) 
        {
            // Printing the characters
            Console.Write(chEnum.Current);
  
            // Break when a space is encountered
            if (chEnum.Current == ','
            {
                Console.WriteLine();
                break;
            }
        }
  
        // Instantiate a copy of CharEnumerator
        // object with the current state
        CharEnumerator chEnumCopy = (CharEnumerator)chEnum.Clone();
  
        // Printing the rest of the characters
        while (chEnumCopy.MoveNext())
            Console.Write(chEnumCopy.Current);
    }
}
