Write a menu-driven program to manage a membership list. Assume that the names and phone numbers of all members are stored in alphabetical order (by last name and then by first name) in the text file MemberPhones.txt. Each record consists of two fields - a name field and a phone field.
The names should appear in a list box when the form is loaded. When a name is highlighted, both the name and phone number of the person should appear in the text boxes at the bottom of the form. To delete a person, highlight his or her name and click on the Delete option from the Update menu. To change either a person's name or phone number, make the corrections in the text boxes and click on the Modify menu option. To add a new member, type his or her name and phone number into the text boxes and click on the menu option Add.
When the Exit menu button is clicked, the new membership list should be written to the file and the program should terminate. See the figure below to see what the result should look like when the program is executed
