The objective of the record entry system is to develop a login-based record keeping system, which has nested menus and different interface for different sets of users.
The application record entry system contains separate interface defined for an administrator and employees. The application provides a basic menu, which has menu options for both types of users. According to the selection made by the user, the user is prompted to enter his login name and password. On successfully validation the user name and password, a menu is displayed to the user according to his level. For example, an employee after logging into the system, can record his log in and log out timings.
The project record entry system demonstrates working with date and time in C, showing ‘*’ characters when user types re password, user authentication and two level of menus for each type of user. The project also adds validation on user input to ensure proper data entry into database.
The project record entry system uses various C concepts, such as while loop, if statement and switch case statement to display the required functionality.
