Objectives: 1) Use inheritance to derive new classes; 2) Understand abstract base classes; 3) Overload base class functions; 4) Override base class virtual functions; 5) Define pure virtual functions; 6) Understand static and dynamic function call binding; 7) Use custom destructors to free dynamically allocated memory.

Project description: In this assignment you will create a class representing a ship, and create two additional classes that inherit from the Ship class, a CargoShip class and a CruiseShip class. The project is geared to give you practical experience with characteristics and C++ implementation details of inheritance and polymorphism.

Requirements: 1. Your program must be split into 7 files. There will be 3 classes (each with separate interface and implementation files), and a driver file. The requirements for these are specified below:

a) The Ship class This is an abstract class Files must be named ship.h and ship.cpp Class must be named Ship Must contain #include guards for SHIP_H Will have these protected members i. A string containing the ships name ii. A double representing the amount of fuel on board (in tons) Must have these public members i. A two parameter constructor that takes the ships name and fuel load (in that order) ii. A void function, fuel, that outputs the ships name and its fuel load (see sample output) iii. A virtual void function, sail, that prints a generic message indicating that the ship is underway iv. A pure-virtual void function, load, that loads the ship with tonnage (cargo) or passengers (cruise)

b) The CruiseShip class This is a derived class that inherits from the Ship class as public Files must be named cruiseship.h and cruiseship.cpp Class must be named CruiseShip Must contain #include guards for CRUISESHIP_H Will have these private members i. Three doubles that indicate the percentage of passengers in Luxury, Upper Deck, and Lower Deck cabins respectively. These values should sum to 1. ii. Three integers that indicate the number of passengers in Luxury, Upper Deck, and Lower Deck cabins respectively. Must have these public members i. A five parameter constructor that takes the ships name, fuel load, and the percentages of passengers in Luxury, Upper Deck, and Lower Deck (in that order) The percentages should sum to 1 This constructor must pass parameters to the constructor in the base class ii. A void function, sail, that overrides the virtual function in the base class, and prints a message indicating that the cruise ship is underway, with a breakdown of the number of passengers in each cabin level (see sample output) iii. A void function, load, that accepts an integer representing the number of passengers as a parameter, and distributes those passengers among the three cabin levels (Luxury, Upper Deck, Lower Deck) per the percentages specified

c) The CargoShip class This is a derived class that inherits from the Ship class as public Files must be named cargoship.h and cargoship.cpp Class must be named CargoShip Must contain #include guards for CARGOSHIP_H Will have these private members i. Two double pointer variables representing tonnage in the forward cargo bay and the aft cargo bay ii. An integer that indicates the maximum cargo capacity for the ship (in tons). Must have these public members i. A three parameter constructor that takes the ships name, fuel load, and cargo capacity (in that order) This constructor should dynamically allocate the memory to represent the cargo bays and initialize them to zero , and must pass parameters to the constructor in the base class ii. A destructor that frees the memory allocated for the cargo bays iii. A void function, fuel, that overloads the function in the base class, and has an integer parameter that indicates the minimum flashpoint for fuel used in cargo ships This function outputs that the flashpoint has been verified to be above the minimum, in addition to the fuel quantity message output by the base class (see sample output) iv. A void function, load, that accepts an integer representing the tons of cargo to be loaded on the ship you must check to ensure that only an amount up to the capacity of the ship is loaded This function should place 47% of the cargo in the forward bay and the remainder in the aft bay, and should output a message that indicates that loading and center of gravity (CG) adjustment have taken place and show the cargo tonnage distribution between the forward and aft cargo bays (see sample output)

d) A driver, or client, file Must be named proj3.cpp Must have two functions as shown below main must be defined first o sailShip This function simulates the ship getting underway with a single function call It has a single parameter: a reference to a Ship object It invokes the sail function through this object o main This function performs the following steps Instantiates a CruiseShip object with initialization of your choosing, outputs the amount of fuel on the ship, loads the ship with a passenger count of your choosing, and invokes the sailShip function with the CruiseShip object as an argument Instantiates a CargoShip object with initialization of your choosing, outputs fuel information (amount and confirmed minimum flashpoint), loads a cargo tonnage amount of your choosing, and invokes the sailShip function with the CargoShip object as an argument
