===================image code=================================
 never post code as an image. You want us to be able to test, modify and improve it, and if it's an image, we just can't do that. Instead always post your code as code-formatted text, as explained in the site's help center docs.
================same answer like an old answer.========================
Hi, you don't need to repost an answer. ---- already posted same answer in this question.
======================comment reputation=========================================
This does not provide an answer to the question. Once you have sufficient reputation you will be able to comment on any post; instead, [provide answers that don't require clarification from the asker.](https://meta.stackexchange.com/questions/214173/why-do-i-need-50-reputation-to-comment-what-can-i-do-instead)
=======================over the head question========================
StackOverflow is not a tutorial site nor search engine replacement. We can help, but it's your job to put some [efforts](https://meta.stackoverflow.com/questions/261592/how-much-research-effort-is-expected-of-stack-overflow-users) on this in first place, including elementary research.

You are asking a question that is [over your head](https://meta.stackoverflow.com/questions/328017/can-you-ask-a-question-you-know-is-way-over-your-own-head) which means it is too broad for Stack Overflow
