C++ Object-Oriented Programming: Shape Hierarchy Implementation

 Ready to dive into object-oriented programming in C++? In this blog post, we'll tackle a programming assignment that involves creating a basic shape hierarchy. This assignment will test your understanding of classes, inheritance, and polymorphism in C++. If you're thinking, 'Who can write my C++ assignment?' We are here to help you.

Problem Description

The Task:

Your mission is to write C++ code to implement a basic shape hierarchy. The hierarchy should include a base class Shape and derived classes Circle and Rectangle. Each class should have methods to calculate area and display information about the shape.

How to Approach the Problem:

Let's break down the problem into manageable steps:

Step 1: Base Class

Create a C++ class named Shape. Define virtual functions for calculating the area and displaying information about the shape.

Step 2: Derived Classes

Create two derived classes, Circle and Rectangle, that inherit from the Shape class. Implement the virtual functions in each derived class.

Step 3: Testing

Test your implementation by creating instances of Circle and Rectangle and calling the area calculation and display methods.

Example

Let's walk through a sample scenario to solidify your understanding. The provided C++ solution serves as a guide to help you implement your own solution. Understand the logic behind each step and adapt it to your programming style.

#include <iostream>

class Shape {
public:
    virtual double calculateArea() const = 0;
    virtual void displayInfo() const = 0;
};

class Circle : public Shape {
private:
    double radius;

public:
    Circle(double r) : radius(r) {}

    double calculateArea() const override {
        return 3.14 * radius * radius;
    }

    void displayInfo() const override {
        std::cout << "Circle - Radius: " << radius << ", Area: " << calculateArea() << std::endl;
    }
};

class Rectangle : public Shape {
private:
    double length;
    double width;

public:
    Rectangle(double l, double w) : length(l), width(w) {}

    double calculateArea() const override {
        return length * width;
    }

    void displayInfo() const override {
        std::cout << "Rectangle - Length: " << length << ", Width: " << width << ", Area: " << calculateArea() << std::endl;
    }
};

int main() {
    Circle circle(5.0);
    Rectangle rectangle(4.0, 6.0);

    // Example usage
    circle.displayInfo();
    rectangle.displayInfo();

    return 0;
}

Conclusion

This programming assignment provides a hands-on opportunity to apply object-oriented programming principles in C++. As you implement the shape hierarchy, you'll not only strengthen your understanding of classes and inheritance but also gain practical experience in designing and using class hierarchies.
