Rectangle initalization

Define a Rectangle struct with float width and float height members. Include a default constructor and a parameterized constructor using member initializer lists. The default constructor should initialize width and height to 1 by using the other constructor. Create instances using both constructors and print the dimensions.

Create a Box struct with member variables for length, width, and height. Add a constructor that uses a member initializer list to initialize these variables and includes validation to ensure all dimensions are positive. Create instances of Box with valid and invalid dimensions and print appropriate messages.

Answer

#include <iostream>

struct Rectangle {
    float width;
    float height;

    // Parameterized constructor with member initializer list
    Rectangle(float w, float h) : width(w), height(h) {}

    // Default constructor with member initializer list
    Rectangle() : Rectangle(1.f, 1.f) {}

    void display_dimensions() const {
        std::cout << "Width: " << width << ", Height: " << height << std::endl;
    }
};

int main() {
    // Using default constructor
    Rectangle rect1;
    std::cout << "Rectangle 1 (default constructor):" << std::endl;
    rect1.display_dimensions();
    std::cout << std::endl;

    // Using parameterized constructor
    Rectangle rect2(5.5, 10.2);
    std::cout << "Rectangle 2 (parameterized constructor):" << std::endl;
    rect2.display_dimensions();

    return 0;
}
