ICS 103 – Project Title: Personal Scheduler Management System 1. Project Description In this project, the student will develop a modular based application using C language. The application should be protected by a password since it will have records of a personal memoranda. The application starts by shown a menu with its maximum functionality as following: - Set Password ( appears only the first time the system runs )
- Edit Password
- Add new Memoranda
o Add new record
o Edit record
o View all contents (table form)
o Delete record ( needs password – approval) - View Previous Memoranda
o Open By date
o Open By Order - Exit Note: The above list is tentative, so we may need to add or remove from it as needed.
The first item in the menu list is appears only if the program being used for the first time by the
super-user (administrator). So, if the application is run for the second time that item list should not
appear. The super-user can create user-names and passwords for new users (only if the system is
multi-user). The memoranda are stored as separate text files. Each file, will contain several records as
needed by the user of the application. Several operations can be performed by the application on
memoranda such as adding, editing, viewing and deleting. Pervious memoranda can be searched using
dates or order.
