List Print

This is a warmup exercise. It is not compulsory, and may be completed individually or with your lab partner.

For this activity, you will be looking at a linked list.

Download list.h, or copy it into your current directory on a CSE system by running

$ cp /web/cs1511/17s2/week11/files/list.h .

Make sure you understand the list and node data structures before beginning this task.

Create a file called listPrint.c that includes the list.h header file. In it, you should implement listPrint, a function which takes a linked list, and prints it to standard output. It should have this prototype:

void listPrint (List l);

It should print out the list in this format, where X indicates the NULL pointer at the end of the list:

1 -> 2 -> 3 -> 4 -> X

Don’t forget to print a new line character!

You should write your own tests in a separate file; listPrint.c should not contain a main. You’ll need to think about how to test a function’s side effects: remember that printing to standard output is a side-effect.

To run some simple automated tests:

$ 1511 autotest listPrint

To run Styl-o-matic:

$ 1511 stylomatic listPrint.c
Looks good!

You’ll get advice if you need to make changes to your code.

Submit your work with the give command, like so:

$ give cs1511 wk11_listPrint

Or, if you are working from home, upload the relevant file(s) to the wk11_listPrint activity on Give Online.
