Product number 2. Quantity sold (positive value) b) Keeps asking the user for values until the user enters 0 as the product number. c) Calculates and prints out the retail value of all products sold in a day. d) Calculates and prints out the maximum sale transaction of the day, as well as the average sale transaction.
You are required to develop a takeaway order management system for a restaurant that delivers pizza and pasta. Your program should maintain a list of customer orders that need to be delivered at any one time. When first run, it should present the user with a menu with the following options: 1. Enter the details of a customer order, which is then added to the order list. 2. Deliver an order, and remove it from the list. The next order to be delivered should always be the order that has been on the list for the longest time. The details of the delivered order should be printed to the screen. 3. Print out details of all the orders in the list. 4. Exit the program. This menu should continue running in a loop until Option 4 is selected by the user. An order's details consist of: - a list of food items - a customer name - a customer contact number - a delivery address - the meal type of the order, i.e., whether or not it is vegetarian, vegan, or contains meat. This information should be determined by the program, based on the food items contained in the order. If there is any food item with meat in the order, then the order's meal type is classed as 'meat'. If there are no meat items but some vegetarian items, then the order is classed as 'vegetarian'. For an order to be classed as 'vegan', there must be no food items that are meat or vegetarian. - a total cost, which is calculated by the program. This is the sum of the prices of all the food items in the order. - A pizza has a list of toppings, which can be one or more of any combination of the following six items: ham, cheese, pineapple, mushrooms, tomato, seafood. For a pizza to be vegetarian, it must not contain ham or seafood. For a pizza to be vegan, it must not contain ham, seafood, or cheese. - A pasta meal has only a single topping, which is one of the following four items: bolognese (meat), marinara (meat), primavera (vegetarian), tomato (vegan). - Pizza and pasta without any toppings can be assumed to be vegan. Each food item also has an associated price, which is calculated by the program as follows: - The base price of either a pizza or pasta meal is $11.50. - Each pizza topping adds an extra $2, except pineapple which adds $2.50 and seafood which adds $3.50. - For the pasta toppings, tomato adds $4, bolognese and primavera each add $5.20, and marinara adds $6.80. For full marks, your design should contain all of the following: - inheritance, with an abstract class as the super class. - an interface which ensures that the price and meal type can always be retrieved from both food items and orders - at least one enum type - at least four classes overall (including the abstract class). Code design and correctness (35 marks) High-level functionality (7 marks) - Implementing overall main menu structure correctly - Adding an entered order correctly to the order list - Removing the oldest order from the order list, and printing that order's details to the screen (using appropriate calls to toString methods) - Printing all order details (using appropriate calls to toString methods) Correctly retrieving and storing order details (8 marks) - Storing the customer's name, contact number, and delivery address with the order - Allowing the user to enter a list of food items, which are stored with the order - Allowing the user to define multiple toppings for each pizza item, and a single topping for each pasta item Price and meal type calculations (8 marks) - Ensuring prices of orders and food items are calculated and reported correctly - Ensuring meal types (meat/vegetarian/vegan) of orders and food items are calculated and reported correctly Design requirements (12 marks) - Sensible overall class design and adherence to good design principles - Modularisation of complex tasks within classes - Validation checks on user input - Appropriate and correct use of inheritance - Appropriate and correct use of an abstract class - Correct use of an interface to ensure price and meal type are implemented as required - Appropriate and correct use of enum type You are required to develop a takeaway order management system for a restaurant that delivers pizza...

2.1 Problem Statement Recently at a University, there has been a huge increase in the number of enrollments. All records of students are entered into a flat file by the registrar when the students register and updated accordingly if there is a need. As a result of the increase in enrollments, this file now has a lot of records. Hence, the statistical officers are now finding it hard to analyze this file to produce various reports for the management. You are required to write a program which will read in this file and produce various reports as outlined. Input File: The input file called StudentRec.txt contains a list of student records. Each record is on a single line and the fields are separated by spaces. The names of the fields are: - Lastname - string - Firstname (initial) - char - ID# - integer - Year of birth - integer - GPA - double An example record may have the following form: Doe J 2021123419903.2 And the format of the actual file is shown below. (Note: the file doesn't show all records and for clarity, fields here are shown separated by tabs, but in the actual file they are separated by spaces). Assume that the file can have a maximum of 300 records. - The first three lines are just header lines and can be discarded - Student id contains an 8-digit number. - Year of birth contains a 4-digit number - GPA is a one decimal place number between 0 - 4 Program Requirements: 1. You must read this file from the current directory and store the records of students into appropriate arrays. 2. Your program should then be able to process the following commands. i.e. the program should provide the user with the following menu. - 1. Print the entire list as per the read file. - 2. Print the entire list with the inclusion of last name initial and age. - 3. Print the list sorted by GPA. - 4. Print the list of students which match a given lastname initial. - 5. Calculate and display the corresponding degree classification (according to GPA) as provided in Table A. - 6. Produce a file called Enrollments.txt (in the current directory), with all the details [Last name, Lastname Initial, Firstname Initial, ID#, Age, GPA, and degree classification]. - 7. Exit the program. Explanation of each menu item. 1. Print the entire class list. This menu item is selected by typing 1, and it should simply print the contents of the file in a suitable format on the screen. (Fields (columns) to display in output are: Last name, Firstname Initial, ID#, Age, GPA, and degree classification) 2. Print the entire class list with the inclusion of last name initial and age. This menu item is selected by typing 2, and it should simply print the contents of the file in a suitable format on the screen with the inclusion of last name initial and age. (Fields (columns) to display in the output are: Last name, Lastname Initial, Firstname Initial, ID#, Age, and GPA) 3. Print the class list sorted by GPA. This menu item is selected by typing 3. The program then prints the list in ascending order of GPA. (Fields (columns) to display in the output are: Lastname Initial, ID#, and GPA) 4. Print the class list of students which match a given lastname initial. The user selects this option by typing 4. Then the user is asked to enter the search initial. If there are students who have that initial, the program prints their record. Otherwise, if no students have last names matching the search initial, a "no matching record found" message is displayed. (Fields (columns) to display in the output are: lastname and id) 5. Calculate and display the corresponding degree classification as per GPA as provided in Table A. The user selects this option by typing 5. The program then calculates and displays the degree classification according to GPA. The format of the resultant display is shown below: [The table (Table A) for degree classification as per GPA is given at the end of this project description] 6. Produce a file called Enrollments.txt (in the current directory), with all the details [Last name, Lastname Initial, Firstname Initial, ID#, Age, GPA, and degree classification]. The user selects this option by typing 6. The program then generates a file "Enrollments.txt" in the current directory with the following details [Last name, Lastname Initial, Firstname Initial, ID#, Age, GPA, and degree classification]. 7. Exit the program. User selects this option by typing 7. This is when the program should end. Note: After each command is processed (except menu 7), the program must display the menu options again. Function to sort an array: There are many algorithms to sort an array according to an ascending or descending criterion. However, we will use the following as it is easiest to understand and CODE. Minimum Element Sort: Go through the array and find the smallest element. Swap it with the first element of the array. Now find the smallest element of the rest of the array and swap it with the second element of the array. And so on. Rather more formally: to sort (x0, ..., xn) into ascending order for i=0 to n-1 begin find the smallest of (xi, ..., xn) 21 Problem Statement Recently at a University there has been a huge increase in the number of Original price was: $15.00.Current price is: $10.00.
