Appendix A: listnode.h

The provided listnode.h contains a self$-$referential structure declaration which you will be using in the

project to represent the List Nodes. Below is a detailed definition of the provided self$-$referential

structure.

typedef struct ListNode$\{$

char $*$ command; $//$ the command for the List Node

char $**$ arguments; $//$ an array of char pointers. NOTE: argv$[0]$ should be the command

with the remainder of argv$[...]$ being the command line arguments typed after the command.

The index following the last command line argument must be set to the NULL pointer

struct ListNode $*$ next; $//$ a pointer to the next List Node

int id; $//$ the id of the List Node

int arguments$\_$length; $//$ the length of the arguments array excluding the ending NULL

pointer

char $*$ file$\_$contents; $//$ represents the file contents of the List Node

$\}$ListNode;

NOTE: Do not modify the members or name of the given struct declaration in listnode.h$.$ Do not add

additional members.

Appendix B: driver.py output

If you run the provided driver.py tester file, you will see an output produced that will award points

accordingly. The tester will award points from $0-2$ for compilation $$ if you receive a $0$ then your code

could not compile; if you receive a $1$ then your code compiles but produced warnings; if you receive a $2$

then your code compiles with no warnings.

Additional tester output will shows points awarded for the provided test cases with scores ranging from

$0-2$ if you receive a $0$ then your output did not match the expected output and had a memory leak; if

you have a $1$ then your output matched the expected output but had a memory leak for the test case; if

you receive a $2$ then your output matched the expected output and had no memory leak for the test

case

An example of a perfect output produced by the driver.py tester would look like the following:

$\{"$scores$"$: $\{"$compiles$"$: $2,"$cd$\_$test": $2,"$cd$\_$test$\_$invalid": $2,$ "execute$-$test": $2,$ "open$\_$test": $2\}\}$
