Removing Page Titles with Child Theme

Hello!

I’ve just set up a child theme and was wondering how to remove the titles off of the pages for the twentythirteen theme.

I’ve seen posts that say to comment-out the title with php, which is fine, but the only file I have available to edit in my child theme right now is my style.css.

So, my question is, can I pull in copies of files in the parent theme folder and edit them in my child theme?

Also, will I have to edit the code every time wordpress updates?
