ECN 1 clarifies usage of the REQUIRED 3 linked-lists.

The Objective

The objective of this assignment is to give you experience working with linked lists. You'll be using command-line arguments, doing file handling, dynamic memory allocation, passing by reference, and comparing strings. You will also continue to practice using good program design and implementation techniques.

The Background

The Automatic Quiz is a program students can run that will present them with questions about material they have covered recently in class. The questions are presented to the student one at a time and the program waits for the student's response. If the answer is right, the student is informed that s/he is correct. If the response is incorrect, the automatic quiz program shows the student the correct answer. The program then proceeds to display the next question.

The program keeps track of the questions that the student has missed. After the student has finished the quiz, s/he is shown the score, and must repeat the questions that had incorrect responses. After finishing the missed questions, a new (hopefully improved) score is calculated and any questions that were missed again are shown to the student along with their correct answers.

The Task

Design and code a project that uses command-line arguments to get the name of the data file from the user to be used for the quiz and uses linked lists to store the lists of questions.

Although your output need not be identical to the above, all information (including the greeting) must be present.

Input Guarantees

All questions will contain 80 characters or less.
All answers are one-word answers and they will contain 30 characters or less.
Any data file we use will have the same format as the ones provided, colors.dat and arith.dat

Further Specifications

You must use separate compilation for this project. You may have as many .c and .h files as you want to fit your project design. Your file that contains main() should be called proj5.c You must have at least 3 files.
You must use linked-lists for this project and you must use three of them. One will be the original list of questions (and correct answers), the second will be the list of once-missed questions (and correct answers), and the third will be the list of never-answered-correctly questions (and correct answers). You may NOT have arrays of questions.
You may use the linked list implementation given in lecture 21. Some of the functions will need minor modification, but some will work as they are (if you choose your data structures carefully when designing).
You MUST use dynamic memory allocation (malloc) to allocate the memory for the nodes of the linked lists. Of course, you must check to see that the space was actually given to you. You must also destroy each list after you are finished using it.
Even though you must keep track of how many questions there were originally and how many were incorrect each time in order to produce a score for the user, you MAY NOT traverse your lists using these numbers and counting nodes. Always traverse lists to their end by examining the next pointer.
You must write your own DestroyList() function, which will free all of the nodes of a linked list that is passed to it.
You may get copies of the data files from my account as in previous projects. The files are called colors.dat and arith.dat and they are in the /afs/umbc.edu/users/s/b/sbogar1/pub directory.
The filename of the data file must be given on the command line
If the program is run with the wrong number of command line arguments, an appropriate message must be printed to the screen using stderr informing the user how to correctly run the program and then then program must exit.
If a file fails to open, you should print an appropriate message to the screen using stderr and exit the program.
You must close the data file as soon as you are finished reading from it.
You must guard your header files.

Submitting the Program

Here is a sample submission command. Since you may have different file names you'll have to adjust it to fit your needs. As always, be sure to submit all of the files necessary for your project to compile.
Note that the project name starts with uppercase 'P'.

submit cs201 Proj5 proj5.c list.c list.h quiz.c quiz.h

To verify that your project was submitted, you can execute the following command at the Unix prompt. It will show the file that you submitted in a format similar to the Unix 'ls' command.

submitls cs201 Proj5
