Given a list of employees, create a simple program that allows the user to insert, delete, display, and search an employee. The program should input 10 full names of employees with employee number as linked list. Also, a list of menus should be displayed. These menus are Insert, Delete, Display and Search. A. Insert - allows the user to insert one employee at a time with corresponding ID number which serves as their link. All employees to be inserted must be inserted at the end of the list. B. Delete – allows the user to delete the employee from the list C. Display – allows the user to display the list of employees D. Search - allows the user to find a certain employee These menus should be in loop once you test every operation based on the listed menu. Use linked list as a data structure in generating a list of employees, and Perform basic operations that can be applied in a linked list

Write a script called finduser that is to be called as follows, where classlist is the name of the classlist file, and username is a particular student's username, either first name or last time. ./finduser classlist username The script should check that the correct number of arguments was received and print an error message if not, check whether the classlist file exists and print an error message if not, print the line of the given username in the classlist file If you have not been doing so all along, you should now add some comments to your script and thoroughly test it! 4. Write the script into your lab report.
Utilize looping to make your Python script for Functionality 2 You should allow users to enter information for five employees at the same time, where the first employee information entry is saved in index [0] and the second entry is saved in index [1], and so on. You want to make sure to enforce the user to enter the following employee information: employeeName, employeeSSN, employeePhone, employeeEmail, employeeSalary. After the user finishes entering the last employee information, they should get a message to allow them to print specific employee information from the saved list. The user can enter values between 1 and 5, where 1 will return the employee information saved in the list index [0], 2 will return the employee information saved in the list index [1] and so on.]to run constantly. while having it run constantly Add Employee – this functionality will allow users to add new employee to the system.

In this laboratory work, you are expected to write a c# console application to make some operations about the customers. Operations and required featurest that you need to cover in your program are following: • Add: This function adds a new person to json file. You need to get inputs from user and adds the new one into json file. • Display: This function displays all people in your json file. • Search: This function let you search with the user id. • Create Password: This function will create a random password for the user and user may choose the length of the password. Password may include numbers and characters. • Exceptions: You need to handle exceptions as well. You should at least handle 3 of exceptional cases. For the case that file can not be found, It is mandatory to catch the exception.
