Homework for next week Generalize solution from last week’s homework so that instead of accepting two arguments it accepts an arbitrary number of them. Change the threshold for a potential sales lead from $100,000 to 1,000,000 USD. List the potential sales leads and the products they purchase. Example output: 6-9-15 cfy

Project revu 6-9-15

In https://web.njit.edu/~yurkowsk/project1/ there are 4 files: https://web.njit.edu/~yurkowsk/project1/names https://web.njit.edu/~yurkowsk/project1/ids https://web.njit.edu/~yurkowsk/project1/hours and https://web.njit.edu/~yurkowsk/project1/rate names contains a list of names, one per line. id contains a list of semicolon separated tuples, one per line consisting of a name and  the literal "ID" followed by a numeric id.. hours  contains list of semicolon separated tuples, one per line consisting of a numeric id and a number indicating the number hours worked that week. rate  contains list of semicolon separated tuples, one per line consisting of a numeric id and an hourly rate for that id.  Assume the rate is USD per hour. Your goal is to write a script which calculates the compensation for the names in first file for the week and output the names followed by a tab followed by a dollar sign followed by that name’s pay. Output one name and pay amount per line.  The output should be in alphabetical order by name regardless of the order in the “names” file. Write the results to standard out, output  any error messages to standard error. Your script should accept 5 command line arguments.   The first will be the name of a directory like the one above,  the next 4  are assumed be file names in that directory whose contents are formatted as the four URLs above and are in the same order as above.
