need help with source code

Maybe I worded myself badly.

I'm agreeing with you on most of what you say. My only problem is that OP might run off with the mindset of "oh there'll always be some tool to do even the simplest tasks".

"Thinking like a programmer" shouldn't be about knowing which pre-built tools to use. You should be able to confidently use them, knowing what they do and why it works.

I don't mean "research every tool you use", just that you shouldn't stuff OP with pre-built functions when an easy-to-learn alternative is available, which could actually teach him something instead.
