Question

Please add code for program.

movies.txt file. LAB 14-2 Plan and Create In this lab, you will plan and create an algorithm for Cheryl Liu, the owner of a candy shop named Sweets-4-You. The problem specification is shown in Figure 14-15. Problem specification Cheryl Liu is the owner of a candy shop named Sweets-4-You. She wants a program that displays the following menu: Menu Options 1 Add Records 2 Display Total Sales 3 Exit If Cheryl selects option 1, the program should call a function that prompts her to enter each salesperson's name and sales amount. The function should save Cheryl's entries in a sequential access file named sales.tct. If Cheryl selects option 2, the program should call a function that calculates and displays the total of the sales amounts stored in the sales.txt file. The program should end only when Cheryl selects option 3. igure 14-15 Problem specification for Lab 142
