| | ganesh_bala, You normally use exit(0) if everything went ok. But if your program detects an error and decides to abort, you would use exit(1). Or you might use exit(1), exit(2), etc, with each exit code meaning some specific error.

 | You should save both date & time. However, use DateTime or Timespan to parse the string time. Example: DateTime date = DateTime.Parse("10:10:10 AM"); Console.WriteLine(date.TimeOfDay); TimeSpan time = TimeSpan.Parse("20:10:10"); Console.WriteLine(time); Or you can use TryParse / TryParseExact methods to parse the string. |
| | Use CSS `width,height, and overflow` properties. PS: Try to learn and use twitter bootstrap |
