Is it alright to borrow someone else's code just for a reference to look upon when you run into trouble?

Question

I've ran into some amazing codes that I borrow just as reference material. In the code name I make sure to put "not my code". Is this acceptable?

Answer 1

keep it private if you wish

Answer 2

You should put a complete reference and check the license of the code (there are some restrictive licenses)
In that way people can see the original source and author

Answer 3

Thanks for the quick reply!

Answer 4

Only everyone else dose it
