Save descriptions to txt format file

Hi there,
I just finished writing my project code in c named Shopping list refer to http://forums.devshed.com/c-programming-42/writing-project-shopping-list-655071.html.

Before I start writing a tutorial and submit, I would like to finalise a final code. Pretend that, I have bought 5 items and items had been entered into a form created in C earlier for example:
1. Rice | 2kg | 0.4$ | 0.8$
2. Beef | 2kg | 2$ | 4$
3. Veg | 3kg | 0.2$ | 0.4$
4. Pork | 4kg | 1.5$ | 6$
5. Toilet|misc| 10$ | 10$

Now, a question is that how can I save those descriptions to txt file at time when I close a form please?

Thank you and regards,

See http://=http://www.cplusplus.com/re.../fopen/]fopen(), fprintf() and fclose().
