say hello world with C++ - Solution in Hacker Rank - hackerranksolutions8

  Objective This is a simple challenge to help you practice printing to  stdout . You may also want to complete  Solve Me First  in C++ before attempting this challenge. We’re starting out by printing the most famous computing phrase of all time! In the editor below, use either  printf  or  cout  to print the string  Hello ,World!  to  stdout . The more popular command form is  cout . It has the following basic form: cout<<value_to_print<<value_to_print; Any number of values can be printed using one command as shown. The  printf  command comes from C language. It accepts an optional format specification and a list of variables. Two examples for printing a string are: printf("%s", string);   printf(string); Note that neither method adds a newline. It only prints what you tell it to. Output Format Print   Hello ,World!   to stdout. Sample Output Hello, World! Solution:- //Say Hello, ...

Rectangle Area in C++ – Solution in Hacker Rank - hackerranksolutions8

 

Problem

Create two classes:

Rectangle
The Rectangle class should have two data fields-width and height of int types. The class should have display() method, to print the width and height of the rectangle separated by space.

RectangleArea
The RectangleArea class is derived from Rectangle class, i.e., it is the sub-class of Rectangle class. The class should have read_input() method, to read the values of width and height of the rectangle. The RectangleArea class should also overload the display() method to print the area (width * height) of the rectangle.

Input Format :

The first and only line of input contains two space separated integers denoting the width and height of the rectangle.

Constraints :

1 <= width, height <= 100

Output Format :

The output should consist of exactly two lines:
In the first line, print the width and height of the rectangle separated by space.
In the second line, print the area of the rectangle.

Sample Input :

10 5

Sample Output :

10 5
50

Explanation :

as width = 10 and height = 5 , so area = width * height = 50

Solution :

//Rectangle Area in C++ - Hacker Rank Solution
#include <iostream>

using namespace std;
/*
 * Create classes Rectangle and RectangleArea
 */
 
/* Rectangle Area in C++ - Hacker Rank Solution START */

class Rectangle 
{
    public:
    int width, height;
    void display() 
    {
        cout << width << " " << height << "\n";
    }
};

class RectangleArea : public Rectangle 
{
    public:
    void read_input() 
    {
        cin >> width;
        cin >> height;
    }
    void display() 
    {
        cout << width * height << "\n";
    }
};

/* Rectangle Area in C++ - Hacker Rank Solution END */

int main()
{
    /*
     * Declare a RectangleArea object
     */
    RectangleArea r_area;
    
    /*
     * Read the width and height
     */
    r_area.read_input();
    
    /*
     * Print the width and height
     */
    r_area.Rectangle::display();
    
    /*
     * Print the area
     */
    r_area.display();
    
    return 0;
}
