Unlike homeworks, labs are required. The labs themselves can be found on NYU Classes newclasses.nyu.edu. Some additional material, typically sample inputs and outputs, may be on the course web site.
Upload your source (e.g., the .c files) and documentation (e.g., the required README file containing instructions on compiling and running the lab) to NYU Classes.
I continually update these notes as the semester progresses so I advise against printing it now, if at all.
