I am writing a paper for school and while I won't get in trouble for forgetting the copyright symbol I am interested in the use of it in case I need it on a more professional basis.
I am currently writing a paper and in my paper I have made reference to the programming languages Java, Python, C, and a few others. Am I required to have a copyright symbol or something similar if it were to be professionally published? Or would it not be required? If someone could explain why or why not it's needed that would be greatly appreciated. I am interested in case I find myself writing a more formal paper in which I would require that knowledge.
