Problem Statement

Write a console-based employee management system through binary File Handling (In order to observe data security, we use binary file format so that data cannot be read directly from the TXT file) which will perform management actions of Employee by taking input from user by showing following three options:

1. 1. Press 1 to ADD AN EMPLOYEE.
   2. Press 2 to DISPLAY FILE DATA.
   3. Press 3 to INCREASE EMPLOYEE SALARY.

After dealing with each option, show prompt to user and continue the program until user press other than ‘y’

Instructions to write C++ program:

• Use Class Employee to declare all Employee’s belongings.
• Make a EMPLOYEE.TXT file for saving Employee records
• Each time program runs, check and delete EMPLOYEE.TXT file if already exists.
• Switch statement will be implemented to perform multiple conditions and to perform different actions based on the conditions. i.e. Option 1, 2 and 3.
• Write functions to perform tasks given in options.

Screenshots for Guidance:

• Initially when program executes, following screen will show to user to get input from the user.

• If user press any other option then 1 at the first time i.e. without creating any file for Employees, then show error to user.

• If User press 1, then take Employee credentials from user using prompt statements as follows and save that data in binary file named EMPLOYEE:[the_ad id=”83970″]

• If User Press 2, then show all Employee Records to user by reading data from the file, which is depicted as follows:

• If User press 3, then ask Employee code from user and then take amount of salary to be increased and update record of that Employee. depicted as follows:
