Ok this stuff isn’t all that hard. It just has a number of different types of tasks. You can allocate one to each person.

1) You have to design a structure that will hold the record

2) You have to have a routine that uses ‘sprintf’ and ‘scanf’ to put the record into a string (and put the string back into a record) that can be saved to a text file, one record per line.

3) You have to have a way of putting menus on the screen and prompting the user to enter a selection

4) You have to be able to prompt for additional information (eg a search string) when processing a menu request

5) You have to have a screen that allows you to list the records and be able to select them for deletion or editing

6) You have to have a screen that prompts for the record information and stores it in the C-structure.

When it starts up, it will open the datafile and populate an array of record structures. When you exit the program, it will write the current content of the array back to a data file.

Altogether it is quite a lot of work. But each module should be something that one person can do in a couple of hours, depending what amount of C that they know.

Focus first on the core functions, and then add the less important ones later. eg you need a menu system and a way to get data from the user and store it in an array of structures, and list them back to the screen. editing/deleting/searching/saving to a file can all come later.

Good luck!
