you are going to write a program to represent various types of packages offered by package-delivery services. You need to create an inheritance hierarchy to represent various types of packages with different shipping options and associated costs. The base class is Package and the derived classes are FlatRatePackage and OvernightPackage. The base class Package includes the following attributes: Sender information: senderName (string), senderAddress (string), senderCity (string), senderState (string) and senderZIPcode (long). Recipient information: recipName (string), recipAddress (string), recipCity (string), recipState (string) and recipZIPcode (long). Other package details: label (string), date (string), weight (double), costPerOunce (double), insuranceType (string), and signatureConfirmation (string). The attributes label, date, weight, costPerOunce represent the package label, the date the package is shipped, the package weight, and the standard shipping fee per ounce, respectively. The insuranceType attribute describes the extra package insurance option. A sender can purchase insurance coverage for mailpieces for up to $5,000 to protect against loss or damage. If the sender does not purchase insurance, then insuranceType is set to none and no extra charge is incurred. If the sender prefers to insure the package, then there are two options based on the packages declared value or desired coverage: up to $1,000, or up to $5,000. insuranceType can thus have the values: none, upto1000, or upto5000. The attribute signatureConfirmation describes another extra service. A sender may request that the receiver signs upon receipt of a package, which incurs an additional charge. This attribute can thus have one of two values, either none or sign. The specialized class FlatRatePackage has four attributes of its own: type (string), width (double), length (double), and height (double). The attribute type refers to the package type, which could be a letter, a paddedEnvelope, a legalEnvelope, or a box. The attributes width, length, and height refer to the package dimensions. The package dimensions are particularly important in deciding if a given mailpiece should be sent in a small box, a medium one, or a large one. The specialized class OvernightPackage has two attributes of its own: overnightFee (double) and tracking (string). The attribute overnightFee represents an additional fee per ounce charged for overnight-delivery service. The attribute tracking represents an additional service charged for providing detailed tracking information of the package. Its value is set to either none if the sender does not want to track the package or track, in which case an additional charge will be incurred. Each class must have the following member functions: a constructor to initialize and validate all the corresponding attributes. For example, you need to ensure that weight, cost, fees all have positive values, and box dimensions are within the dimensions given in the table below. set and get functions to assign values and retrieve attribute values (as needed) as well as print function to print the packages attributes on the screen (specialized and inherited), and its shipping cost. its own calculateCost function that calculates and returns the cost associated with shipping a certain package. The base class Packages calculateCost function should determine the cost by multiplying the weight by the costPerOunce and adding the insurance and signature confirmation fees if applicable. Signature confirmation costs an additional $2.90. Insurance fees are based on the items declared value or insuranceType as shown in the table below: Insurance Type Insurance Fee ($) Upto1000 5.25 Upto5000 5.50 FlatRatePackage should redefine calculateCost function so it calculates the shipping cost based on the package type and dimensions and independent of its weight. A FlatRatePackages cost is a flat fee that depends on the package type and dimensions as summarized below. CalculateCost should also take into account extra services costs such as insurance and signature confirmation fees if applicable. Width Length Height Cost ($) Box < 12 < 12 < 5 20.10 Box < 11 < 8 < 5 17.75 Box < 8 < 5 < 2 11.30 PaddedEnvelope 9.45 LegalEnvelope 7.65 Letter 3.20 OvernightPackage should redefine calculateCost function so it adds the additional fee per ounce to the standard cost per ounce before calculating the shipping cost. CalculateCost should also take into account extra services costs such as insurance, signature confirmation, and tracking fees if applicable. Tracking incurs an additional charge of $5.50 per package. After you design your base and derived classes, you need to design a PackageInventory class that keeps track of all packages sent. The PackageInventory class has the following attributes: vector packages; vector flatRatePackages; vector overnightPackages; The PackageInventory class has a constructor as well as the following member functions: - CreateNewPackage that creates a Package object, pushes it into the packages vector, and displays a message that the package was successfully added. If any package attribute value is not valid, you should not add an object to the vector and should print appropriate error message. - CreateNewOvernight that creates an OvernightPackage object, pushes it into the OvernightPackages vector, and displays a message that the package was successfully added. If any package attribute value is not valid, you should not add an object to the vector and should print appropriate error message

CreateNewFlatRate that creates a FlatRatePackage object, pushes it into the FlatRatePackages vector, and displays a message that the package was successfully added. If any package attribute value is not valid, you should not add an object to the vector and should print appropriate error message. - PrintAllPackages that prints the details of all packages in the packages vector: sender and receiver information, package label, date, weight, insurance option, signature confirmation requirements if any, and shipping cost. Note: when printing sender and recipient information (name, address, and city), you get extra credit if you print spaces between words. Each new word starts with an uppercase letter. For example: Sender: Lou Brown 1 Main St Boston, MA 11111 Recipient: Mary Smith 7 Elm St New York, NY 22222 Label: FY0002 Mailed on: 12/03/2016 Weight: 8.5 Insurance: none Signature: none Cost: $4.25 - PrintAllFlatRatePackages that prints the details of all packages in the FlatRatePackages vector in a neat fashion: sender and receiver information, package label, date, weight, type, dimensions, insurance option, signature confirmation requirements if any, and shipping cost. - PrintAllOvernightPackages that prints the details of all packages in the OvernightPackages vector in a neat fashion: sender and receiver information, package label, date, weight, insurance option, signature confirmation, tracking option, and shipping cost. - PrintShippedonMonthYear that prints the details of all base and derived packages shipped on a specific month and year. - CalculateTotalCost that calculates and prints the total cost of a specific type of packages. This includes the shipping cost of all packages in a specific vector. - ProcessTransactionFile that opens the transaction file and processes its lines one by one. If the file could not be opened, you should print appropriate message. Note: Make sure to break up your classes into .cpp and .h files and declare any member function that does not modify the attributes as constant. After you design all your classes, you need to write a main program that displays the address information and calculates the shipping costs for several packages. The main program instantiates an object of type PackageInventory and calls a method to read a transaction file and process its commands. Your main should look like this: int main() { PackageInventory inventory; inventory.ProcessTransactionFile("TransactionFile.txt"); return 0; } The transaction file contains several commands and corresponding values that will create new packages and add them to the corresponding vectors, invoke get functions to obtain the address information of the sender and the recipient, then print the two addresses as they would appear on mailing labels. Also, call each Packages calculateCost member function and print the result. The commands and their formats are: - CreateNewPackage senderName senderAddress senderCity senderState senderZIPcode recipName recipAddress recipCity recipState recipZIPcode label date weight costPerOunce insuranceType signatureConfirmation - CreateNewFlatRate senderName senderAddress senderCity senderState senderZIPcode recipName recipAddress recipCity recipState recipZIPcode label date weight costPerOunce insuranceType signatureConfirmation type length width height - CreateNewOvernight senderName senderAddress senderCity senderState senderZIPcode recipName recipAddress recipCity recipState recipZIPcode label date weight costPerOunce insuranceType signatureConfirmation tracking OvernightFee - PrintAllPackages - PrintAllFlatRatePackages - PrintAllOvernightPackages - PrintShippedonMonthYear month year - CalculateTotalCost specificVector
