List Sum

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 listSum.c that includes the list.h header file. In it, you should implement listSum, a function which takes a linked list and returns the sum of the values in the linked list.

It should have this prototype:

int listSum (List l);

You should write your own tests in a separate file; listSum.c should not contain a main.

To run some simple automated tests:

$ 1511 autotest listSum

To run Styl-o-matic:

$ 1511 stylomatic listSum.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 wk13_listSum

Or, if you are working from home, upload the relevant file(s) to the wk13_listSum activity on Give Online.
