    static void Main(string[] args) {
      //char variable declaration
      sbyte num = -120;

      //printing value
      Console.WriteLine("num: " + num);
      //printing type of variable
      Console.WriteLine("Type of num: " + num.GetType());
      //printing size of a decimal 
      Console.WriteLine("Size of a sbyte variable: " + sizeof(sbyte));

      //hit ENTER to exit
