Hello Sandeep, First of all a warm welcome to Techulator, this is technology related knowledge sharing site. Here you can earn nice amount of cash credits by writing decent articles. As a new member I'd recommend you to go through the FAQ and Forum Posting Guidelines.
You can ask questions in the forum section if you have further problems. The members will be more than happy to help you.
I'd personally advise you not to use chat keywords like 'N' instead of 'and'. Also always try to make full sentence with proper grammar and spelling. This way you will also enhance your English knowledge.
