Where find welcome to jamrock zippy?
Look them up in a good Welcome to jamrock zippy reference. Continuing our example from above, suppose the input file consists of lines with a username and an integer test score. We might use the files we opened above by copying each username and jamdock from the input file to the output file. However, when it hits the end of the file, iamrock returns the special value EOF. So, testing the return value against EOF is one way to stop the loop.
