■ Look up an employee in the dictionary
■ Add a new employee to the dictionary
■ Change an existing employee's name, department, and job title in the dictionary
■ Delete an employee from the dictionary
■ Quit the program
When the program ends, it should pickle the dictionary and save it to a file. Each time the program starts, it should try to load the pickled dictionary from the file. If the file does not exist, the program should start with an empty dictionary.

7. Employee Management System
This exercise assumes you have created the Employee class for Programming Exercise 4. Create a program that stores Employee objects in a dictionary. Use the employee ID number as the key. The program should present a menu that lets the user perform the following actions:
Look up an employee in the dictionary
Add a new employee to the dictionary
Change an existing employee’s name, department, and job title in the dictionary
Delete an employee from the dictionary
Quit the program
When the program ends, it should pickle the dictionary and save it to a file. Each time the program starts, it should try to load the pickled dictionary from the file. If the file does not exist, the program should start with an empty dictionary.

Flowchart for student interface program please.
Create a program to enter grades and calculate averages and letter grades.
Need a class which will contain:
Student Name
Student Id
Student Grades (an array of 3 grades)
A constructor that clears the student data (use -1 for unset grades)
Get functions for items a, b, and c, average, and letter grade
Set functions for items a, n, and c
Note that the get and set functions for Student grades need an argument for the grade index.
Need another class which will contain:
An Array of Students (1 above)
A count of number of students in use
You need to create a menu interface that allows you to:
Add new students
Enter test grades
Display all the students with their names, ids, test grades, average, and letter grade
Exit the program
Add comments and use proper indentation.
Nice Features:
I would like that system to accept a student with no grades, then later add one or more grades, and when all grades are entered, calculate the final…

- Program Specification For this assignment you will write a program to help people record the events of their day by supplying prompts and then saving their responses along with the question and the date to a file. Functional Requirements This program must contain the following features: Write a new entry - Show the user a random prompt (from a list that you create), and save their response, the prompt, and the date as an Entry. Display the journal - Iterate through all entries in the journal and display them to the screen. Save the journal to a file - Prompt the user for a filename and then save the current journal (the complete list of entries) to that file location. Load the journal from a file - Prompt the user for a filename and then load the journal (a complete list of entries) from that file. This should replace any entries currently stored the journal. Provide a menu that allows the user choose these options Your list of prompts must contain at least five different prompts.…arrow_forwardSearching - a user should be able to search by ID or by item name create only one menu item for searching a user should be able to enter the name of the item using any case, (for example, sTRolleR) you may wish to store items in all lower/upper case to expedite the search write one search function that can search by ID and name and goes through the array of structs/objects only once show the entire record if found or an appropriate message if not Sorting - sort by any field write one function to sort by any field using a parallel array of pointers use Bubble Sort is not the most effective but the easiest to modify. do not copy and paste sort code five times into the same function. sorting using pointers is faster because you have to swap pointers only, which are normally stored in 4 bytes each; it also allows you to preserve the original order of the items If you choose to have a submenu, a submenu must have an option to go back to the previous menu or main menu if a user got…arrow_forwardData structures dict_contains_keys(items:set, example_dict:dict)->bool This function will have two parameters.

This module should implement the following functions: • getDonor(donorId): returns a donor by id. • addDonor(donor): adds a donor to the list of donors; donorID should be autoassigned a random number. • updateDonor(donor): updates the donor having the matching donorID. • deleteDonor(donorID): delete the donor with donorID from the list of donors, only if they are not associated with any books. 2.

The application must first display the list after which the application must remove 5 random items from the list. The application must then show the updated list with 5 of the items removed. After this is done, the application must add 7 new items to the list. These items must be completely new and not the ones that were on the list initially. The application must then output the updated list with the added items.
