Article without proper description is not acceptible. If you are submitting code snippets, you must explain the code with proper description. Alos, the subtitle of the article is not descriptive.

The code snippet needs proper documentation. It seems to be incomplete code snippet. Any code presented should be complete, easy to understand and properly documented, so that any one can understand the program.
