When you started this lesson you clicked a button to copy a set of files into your own examples directory (i.e., the directory named examples inside your home directory). Assuming that the files were successfully copied, you now have one file named ``joints.c'' in that directory.
Use Emacs to view ``joints.c''.
You can also view the program as joints.c.
