using System; 

 

class MainClass { 

  public static void Main() { 

    int? count = null; 

    int? result = null; 

 

    int incr = 10; 

 

    count = 100; 

    result = count + incr; 

 

    if(result.HasValue) 

      Console.WriteLine("result has this value: " + result.Value); 

    else  

      Console.WriteLine("result has no value");     

 

  } 

}

result has this value: 110
