The original tar file is cprogramminglab-handout.tar and the writeup is cprogramminglab.pdf. My solution is in cprogramminglab-handout-solution.

After untaring cprogramminglab-handout.tar, you follow the instructions in cprogramming.pdf to untar the folder. You can run make directly, but you cannot run make test, since ./driver.py is used.

• To run make test:

1. Install python2 in your environment;
2. Change ./driver.py in Makefile to python2 ./driver.py;
3. Run make test;

• To use driver.py directly:

1. Install python2 in your environment;
2. Run python2 driver.py.

The most tricky part in this lab is to pass trace case 11 and 12. You can try commentting out the 2 lines in queue.c marked as "IMPORTANT", which would cause memory leak. Lesson: when a function relies on the success of a series of memory allocation, remember to free all previous allocated memory, in case any one of the memory allocation step fails.

I read the book: The C Programming Language before doing this lab. The note when reading the book is in folder TheCProgrammingLanguage.
