Part 1 Create a class named Room which has two private data members which are doubles named length and width. The class has five functions: a constructor which sets the length and width, a default constructor which sets the length to 12 and the width to 14, an output function, a function to calculate the area of the room and a function to calculate the parameter. Also include a friend function which adds two objects of the room class. Part 2 Copy your class definition from the previous Part 1 then write the definitions of the 5 functions which are in your class. Part 3 Write a complete in Visual Studio to test your class and all of its functions. Upload the .cpp file as well as the results of running the program.

C++ code:

#include <bits/stdc++.h>

using namespace std;

// forward declaration

class Room1;

// class Room declaration

class Room {

    // two private data members, length and width

    private:

        double length;

        double width;

    public:

    //  constructor which sets the length and width

      Room(int l,int w){

          length = l;

          width = w;

      }

     // default constructor which sets the length to 12 and the width to 14

      Room(){

          length = 12;

          width = 14;

       }

         // function to calculate the area of the room

      double getArea(){

         return length * width;

      }

      //  function to calculate the parameter

      double perimeter(float l, float w){

          return((2*l) + (2*w));

      }

     // friend function declaration

      friend int add( Room , Room1 );

};

class Room1{

    private:

       double length;

       double width;

    public:

   // constructor which sets the length and width

      Room1(int l,int w){

            length = l;

            width = w;

      }

     // default constructor which sets the length to 12 and the width to 14

      Room1(){

            length = 12;

            width = 14;

        }

     // function to calculate the area of the room

      double getArea(){

        return length * width;

      }

      // function to calculate the parameter

      double perimeter(float l, float w){

        return((2*l) + (2*w));

      }

      // friend function declaration

      friend int add( Room , Room1 );

};

// Function add() is the friend function of classes Room and Room1

// that accesses the member variables length and width

int add(Room objectA, Room1 objectB)

{

   return ((objectA.length + objectA.width)+(objectB.length + objectB.width));

}

// The main function

int main()

{

    

    Room R1( 4.5, 8.5 );

    cout << "Area: " << R1.getArea() << endl;

    cout<< "perimeter: " << R1.perimeter(4.5,8.5) <<endl;

    // friend function which adds two objects of the room class

    Room objectA;

    Room1 objectB;

    cout<<"Sum: "<< add(objectA, objectB);

    

    return 0;

}

C++ Create a class for working with fractions. Only 2 private data members are needed: the int numerator of the fraction, and the positive int denominator of the fraction. For example, the fraction 3/7 will have the two private data member values of 3 and 7. The following methods should be in your class: a. A default constructor that should use default arguments in case no initializers are included in the main. The fraction needs to be stored in reduced...

Write a program in which define a templated class mySort with private data members as a counter and an array (and anything else if required). Public member functions should include constructor(s), sortAlgorithm() and mySwap() functions (add more functions if you need). Main sorting logic resides in sortAlgorithm() and mySwap() function should be called inside it. Test your program inside main with integer, float and character datatypes.
