Ship Cruiseship And Cargoship Classes In C Language I Use Visual

Ship, CruiseShip, and CargoShip Classes (in C++ language i use visual studios to code with) design a Ship class that has the following members: - A member variable for the name of the ship (a string) - A member variable for the year that the ship was built (a string) - A constructor and appropriate accessors and mutators - A virtual print function that displays the ship's name and the year it was built (nobody seems to get this part right) design a CruiseShip class that is derived from the Ship class. The CruiseShip class should have the following members: - A member variable for the maximum number of passengers (an int) - A constructor and appropriate accessors and mutators - A print function that overrides the print function in the base class. The CruiseShip class's print function should display only the ship's name and the maximum number of passengers. The CargoShip class should have the following members: - A member variable for the cargo capacity in tonnage (an int) - A constructor and appropriate accessors and mutators - A print function that overrides the print function in the base class. The CargoShip class's print function should display only the ship's name and the ship's cargo capacity. Demonstrate the classes in a program that has an array of Ship pointers. The array elements should be initialized with the addresses of dynamically allocated Ship, CruiseShip, and CargoShip objects. The program should then step through the array, calling each object's print function.

Ship Cruiseship And Cargoship Classes In C Language I Use Visual

Introduction

The design and implementation of class hierarchies in object-oriented programming (OOP) provide a powerful way to model real-world entities and relationships. In this context, the task involves designing a base class Ship and two derived classes, CruiseShip and CargoShip, with specific attributes and behaviors. The use of C++—a language supporting inheritance, polymorphism, and encapsulation—facilitates this modeling. Demonstrating these classes with dynamic memory allocation and polymorphic method calls underscores key OOP principles such as abstraction, inheritance, and dynamic binding.

Design of the Base Class: Ship

The Ship class serves as the foundation for more specialized ship types. It encapsulates the common attributes of ships: name and year built. The class includes a constructor, accessors and mutators for data encapsulation, and a virtual print function to display basic information. This setup aligns with best practices in class design, ensuring that derived classes can override behavior appropriately.

Implementation of the Ship Class

The Ship class is defined with private member variables for name and built. The constructor initializes these variables, while accessors and mutators manage data access. The virtual print method outputs the ship's name and year built, providing a default implementation that derived classes can override.

Derived Class: CruiseShip

The CruiseShip class inherits from Ship and adds specific functionality related to passenger capacity. The additional member variable maxPassengers reflects the maximum number of passengers the cruise ship can accommodate. Its constructor initializes both inherited and new members. The print method overrides the base class method, focusing on displaying only the ship’s name and maximum passengers, demonstrating polymorphism.

Implementation of the CruiseShip Class

In CruiseShip, the print function is overridden to display pertinent information. This approach exemplifies method overriding, allowing different ship types to present customized outputs while sharing a common interface.

Derived Class: CargoShip

The CargoShip class also extends Ship, adding a member variable tonnage to represent cargo capacity in tons. Its constructor sets this value, and the print method is overridden to display only the ship’s name and cargo capacity, adhering to the polymorphic behavior pattern.

Implementation of the CargoShip Class

This class demonstrates how specialization extends the base class to include relevant attributes while preserving the common interface for printing information.

Demonstration via Polymorphism

The main function showcases polymorphism by creating an array of Ship pointers. Each pointer references dynamically allocated objects of Ship, CruiseShip, and CargoShip. The array is then traversed, invoking the print method on each object. Thanks to virtual functions, the appropriate overridden method executes, ensuring the correct information is displayed based on object type.

Code Implementation

include <iostream>


include <string>


using namespace std;


class Ship {


private:


string name;


string yearBuilt;


public:


Ship(const string& n, const string& y) : name(n), yearBuilt(y) {}


virtual ~Ship() {} // Virtual destructor for proper cleanup


string getName() const { return name; }


string getYearBuilt() const { return yearBuilt; }


void setName(const string& n) { name = n; }


void setYearBuilt(const string& y) { yearBuilt = y; }


virtual void print() const {


cout 

}


};


class CruiseShip : public Ship {


private:


int maxPassengers;


public:


CruiseShip(const string& n, const string& y, int p) : Ship(n, y), maxPassengers(p) {}


void print() const override {


cout 

}


};


class CargoShip : public Ship {


private:


int tonnage;


public:


CargoShip(const string& n, const string& y, int t) : Ship(n, y), tonnage(t) {}


void print() const override {


cout 

}


};


int main() {


Ship* ships[3];


ships[0] = new Ship("SS Explorer", "1990");


ships[1] = new CruiseShip("Sea Voyager", "2005", 2000);


ships[2] = new CargoShip("Cargo Master", "2010", 50000);


for (int i = 0; i 

ships[i]->print();


}


for (int i = 0; i 

delete ships[i];


}


return 0;


}

Conclusion

This implementation exemplifies core object-oriented programming principles through the design of a base class Ship and derived classes CruiseShip and CargoShip. The use of virtual functions facilitates dynamic binding, allowing each ship type to present its information appropriately. The approach not only fosters code reuse and extensibility but also enhances clarity and maintainability. Such class hierarchies are prevalent in software modeling real-world assets, demonstrating the practical utility of OOP concepts in C++ programming.
