Practical-17

Write a cpp program for overloaded constructors.​

Introduction

Code​

Practical-17.cpp


#include <iostream>

//We can use constructors to quickly create an object
//with some predetermined values.
class Rectangle
{
    int l, b;

public:
    //Creating a constructor without any arguments
    Rectangle()
    {
        l = 0;
        b = 0;
        cout << "Constructor without arguments" << endl;
    }

    //Constructor with two arguments
    Rectangle(int l,  int b)
    {
        //'this' is a keyword that refers to the current object
        this->l = l;
        this->b = b;
        cout << "Constructor with arguments" << endl;
    }
};

void main()
{
    //Creating objects for both constructors
    Rectangle r1;
    Rectangle r2(5, 10);

    return 0;
}

Output​

Constructor without arguments
Constructor with arguments
