Some do some don't
But it may seem like someone has copied them but he might off just found it on his own I do not think it's bad at all

Everyone has/does copy something from other people E'G style' ideas so im sure they do

It sort of depends on what you're copying, how much, and how you're using the code.

It is perfectly fine to look something up on the Internet, such as problems/solutions, case studies, and for example a useful snippet on StackOverflow. You're not only doing this to improve your application, but also to learn and develop your own skills. Everyone looks something up every now and then, no developer knows "everything". I wouldn't consider this "copying" code. The code that you are using is posted and made public for that very reason, to help people when they're stuck on something.

But, if you are the kind of person who downloads some sort of open source application, deploy it, claim that you made it, while you probably don't even understand the code one bit... then yes, you're copying, and you should feel bad.

Do you believe coders use other code as reference and or utilize it within their own code? Do you believe this is bad? Why or Why Not?

Are you going to re-invent the wheel each time you build an application?

I think you would have 'copied' other works if you are any good at programming.
There is not a single answer to any solution within programming so you can learn by looking at other solutions and methods of achieving the same answer.

I don't mean go and copy word for word but to understand a particular function or something like that is perfectly fine and I would encourage it to be honest.

Don't just completely copy people though.

Some people *with* the permission copy the entire program of someones and re-engineer the entire thing to make there own version.

Like if you copy a whole applications code and claims it's yours, then that's bad but if you copy some code to implement into your own code then that's fine, that is what most programmers started out with, like myself.
