I recently found a website that you can use to find literally anything as long as you know how to use it. It is kind of the goal that the company that is running the website has. This means you should be able to get such things as account checker source code, like some kind of hacking tools of source codes.

It's pretty neat:

Disclaimer: It might be a website for pros though, so don't get demotivated if you don't get the answers you are looking for immediately. It requires some perseverance and it involves a few presses on the keyboard. You might even need to use the device that we know as the mouse to invoke a few clicks here and there. Go to the website on your own responsibility though. I won't be accountable for the bad things that might happen to you or to your computer during the process.

On a more serious note.

What are you trying to achieve? Learn? Copy? It might be better to learn to code the stuff yourself. That will also teach you how to look for things.
Also next time you post a thread, please try to sound a little bit less lazy and show actual interest that you actually tried searching. Another actual useful link for you: http://www.catb.org/esr/faqs/smart-questions.html .

On another note, there's sites like this where you can search code snippets themselves: https://searchcode.com/
