Customer Database Interface in C



Overview

I created a mock customer database interface in the C programming language for ICS 212, Program Structure. The application has no GUI, but is designed to be used through the command-line interface (CLI). When the application is started a menu is displayed prompting the user to choose one of several options. Options include:

  1. Add Record
  2. Modify Record
  3. Print Record
  4. Print All Records
  5. Delete Record
  6. Quit


Implementation of the application took about a week. I was the sole author of this project, and it was written entirely in C. It was also the first program I have written that makes use of command-line arguments.

Programming this application gave me a deeper understanding of pointers, including pointers to pointers and why they can be useful. The experience also engrained in me the importance of testing/validating user input, and handling unexpected input in an appropriate manner. This project, and having Ravi Narayan as a teacher, made me love the C programming language.
