Yes, again you can. But I strongly advised beginners to read more first, than to be in a hurry to make a post. Because it is always likely that whatever question they may have to ask has already been answered. The only exception is when there is a more recent information or unique angle to it.

To answer this question, use the search function to search for this. It has already been answered in the past.
The search function (https://bitcointalk.org/index.php?action=search) works like Google search.

There's nothing like running a code, it's just an understanding of how to insert the necessary quote pattern as the previous reply you got explains, same also I do by quoting you,if you want to know how it's been done in another way, then click on quote under my reply or the previous one you got from the other user, you can see it by the right side on the top of my post here, same applies to every other posts coming, once you press the quote button, then you will see the  explanation to how it works there.
