Assignment

Create a program that reads in a list of CSCI classes from a file found at /public/pgm2/classes.csv. Store the list in an array of structures. Then, give the user to have a number of options to query the list of classes and get information about them. You must include the following query options:

  • Quit
  • Print all classes
  • Print all classes by course id (e.g., CSCI 112)
  • Print all classes by days of course meeting (e.g., MWF)
  • Print all classes under a certain number of seats

You should also add at least one more option that is different from all the options listed above.

Sample output

You do not need to match the sample output formatting.

Choices:
a - print all available classes
n - print class given course id
d - print all classes given day of week combo
s - print all classes under certain # seats
q - quit

Hints

  • You can use gets to read in input with spaces without a newline character. fgets also reads input with spaces, but it keeps the newline. gets is deprecated in newer C compilers, but you can use it for this assignment.
  • If gets (or fgets) is not allowing you to enter input, it may be consuming a previous newline left behind from a scanf. To fix this, you can add a getchar() before your gets.
  • Remember that string assignment must be done with strcpy (unless it’s in a variable declaration/initialization).
  • Use strtok to separate parts of the input strings.
  • Start early!

Extras

If you want, you can include the following requirements in your program. They are ungraded, though, so ignore if you want.

  • Allow your program to read files containing any number of classes, rather than hard-coding the number of lines from the file.
  • Give a warning if the file doesn’t exist.
  • Provide a nice output if the user enters a disallowed choice.
  • Don’t use gets.
  • If no class is returned by a query, print a special message.

Grading - 100 points

  • 5 points – comments explaining what your program does
  • 5 points - code is indented so that it is readable
  • 5 points - there are no global variables
  • 5 points – compiles successfully with -Wall – no warnings except for about get
  • 5 points – successfully reads all classes from classes.csv
  • 10 points – stores info for all classes in an arry of structs
  • 5 points – compiles and links with makefile
  • 5 points - there are at least four different files
  • 5 points - implements printing all classes correctly
  • 5 points - implements printing class by id correctly
  • 5 points - implements printing class days of week correctly
  • 10 points - implements printing classes under certain # seats correctly
  • 5 points - offers one more option to users
  • 10 points - extra option is implemented correctly
  • 10 points - your struct is in its own header file
  • 5 points - output is printed neatly

Grading turnaround

This program will be graded with scores in Brightspace by 5pm on June 2nd.
