8. Name and Email AddressesWrite a program that keeps names and email addresses in a dictionary as key-value pairs. The program should display a menu that lets the user look up a person’s email address, add a new name and email address, change an existing email address, and delete an existing name and email address. The program should pickle the dictionary and save it to a file when the user exits the program. Each time the program starts, it should retrieve the dictionary from the file and unpickle it.
How would the user be able to use the program?

- Please answer Java OOP homework scenario below: You have been hired by the National Insurance Company to create a program to track insurance policies for all its customers. National Insurance provides three types of insurance: automobile, home and life insurance. The program should be able to track up to 100 policies. Based on the provided information, create an efficient, object-oriented solution with good design principles that will allow a user to manage policies. To do this, the solution should have a menu with the following capabilities: Add Policy o This capability will allow a user to add a policy. The user should specify if the policy is for home, auto, or life. Once the type of policy has been selected, the user should be prompted for all required fields for the policy type. Remove Policy o This capability will allow a user to select any policy and remove it from the list. View policies o This capability will allow a user to see all the policies. All policy fields…arrow_forwardWhat are the two errors in my pseudocode?Module getAverage(Integer value1, Integer value2, Integer value3) Declare Integer average average = value1 + value2 + value3 / 3 Display average End Modulearrow_forwardWhere did I make an error in my pseudocode module???Code:Module main() Call raiseToPower(2, 1.5) End main Module raiseToPower(Real value, Integer power) Declare Real result Set result = value ^ power Display result End raiseToPowerarrow_forward

- Where did I make an error in my pseudocode module???Code:Module main() Call raiseToPower(2, 1.5) End main Module raiseToPower(Real value, Integer power) Declare Real result Set result = value ^ power Display result End raiseToPowerarrow_forwardI need help writing pseudocode for calculating class score average by putting in 5 test scores, and showing the average from all 5 inputs and the GPA score.Starting with 3 functions outside of a main module. The functions are getScore(), getGPAPoint(Integer score), and getAverage(). Function getscore is an input for a grade as a class percentage. Function getGPAPoint will calculate the score into a GPA point and return as a float (values of 90-100 as 4.0, 80-89 as 3.0, 70-79 as 2.0, 60-69 as 1.0, and anything below 60 as 0.) Function averageGPA will finally make a call to both previous functions when the user inputs numbers 5 times that then calculates the average (add up all the scores, divide by 5) and the average grade alongside displaying the average GPA. End result is a main module that makes a proper call to the averageGPA function and display its results. Need help with this!arrow_forwardPlease original work Why is integration between data collection and business analysis so important to success in an organization that uses business analytics?
