• correction: There was a bug in my flattenstatus script; if you ran it before 8:20am on Wednesday, April 13th, then you may have incorrect data. Re-run it to generate a fresh and correct copy. (20160413)

To implement a programmatic solution (ie simulation) of a real life process- the obtaining, processing, and display of your status in the course.

In addition to the new skills required on previous projects, to successfully accomplish/perform this project, the listed resources/experiences need to be consulted/achieved:

• you can calculate percentages
• ability to open and access data from files
• using loops to automate a process
• using functions to organize your code

Throughout the semester, you've been accumulating points for your class participation, journal, and projects.

This information has been accessible via the status tool.

Throughout the semester, your class-related activities have been numerically captured and made available to you via the status tool.

Now that we are nearing the end, and your programming skillset is significantly expanded, I would like you to write a program to take this data and calculate your grade (reflective of currently recorded data).

I've designed a tool that will take all your status data and 'flatten' it… converting all the necessary data into one stream of values. To obtain this data, simply run the flattenstatus command and the file status.flat will be created in your current working directory.

For example:

lab46:~/src/cprog/gfo0$ flattenstatus
lab46:~/src/cprog/gfo0$ cat status.flat
-1 0 1 1 0 0 1 1 1 1 1 1 1 1 1 1 0 0 0 1 1 1 1 -2 1 1 1 0 1 0 1 0 1 0 0 1 -3 11 13 6 9 4 9 5 9 6 9 19 20 6 0 18 20 -4
lab46:~/src/cprog/gfo0$ 

Your program needs to do the following:

• check for and open the status.flat file
  • if error occurs, display message and exit
• reading one integer at a time, load the values into an array according to their category
• there will be three categories (arrays), each one identified by a header/sentinel value:
  • -1 indicates the start of participation data (28% of grade)
  • -2 indicates end of participation data / start of journal data (36% of grade)
  • -3 indicates end of journal data / start of project data (36% of grade)
  • -4 indicates end of project data (and end of data stream)
• once loaded into their arrays, calculate the grade component
• tally up all three, and print out the results

Final program output should resemble the following:

lab46:~/src/cprog/gfo0$ ./mygrade
Participation Component: 20 / 28
Journal Component:       20 / 36
Projects Component:      30 / 36
Total:                   70 /100
lab46:~/src/cprog/gfo0$ 

To successfully complete this project, the following criteria must be met:

• Code must compile cleanly (no warnings or errors)
  • Use the -Wall flag when compiling.
• Output must be correct, and resemble the form given in the sample output above.
• Code must be nicely and consistently indented (you may use the indent tool)
• Code must utilize the algorithm presented above
• Code must be commented
  • have a properly filled-out comment banner at the top
  • have at least 20% of your program consist of //-style descriptive comments
• Track/version the source code in a repository
• Submit a copy of your source code to me using the submit tool.

To submit this program to me using the submit tool, run the following command at your lab46 prompt:

$ submit cprog gfo0 gfo0.c
Submitting cprog project "gfo0":
    -> gfo0.c(OK)

SUCCESSFULLY SUBMITTED

You should get some sort of confirmation indicating successful submission if all went according to plan. If not, check for typos and or locational mismatches.
