Practical 5 OOP

 PRACTICAL – 5.1

Create  a  'DISTANCE'  class  with  : -feet  and  inches  as  data  members, -member  function  to input distance-member function to output  distance-member function to add two distance objects. Write a main function to create objects of DISTANCE class. Input two distances and output the sum.

#include <iostream>

using namespace std;

class Distance

{

    int feet, inch;

public:

    Distance(int a = 0, int b = 0)

    {

        feet = a;

        inch = b;

    }

    void Oputput()

    {

        cout << "Feet = " << feet << endl

             << "Inch = " << inch << endl;

    }

    void addiction(Distance &a, Distance &b)

    {

        cout << "Feet = " << (a.feet + b.feet) << endl

             << "Inch = " << (a.inch + b.inch) << endl;

    }

};

int main()

{

    Distance r(10, 13), j(11, 12);

    r.addiction(r, j);

    j.Oputput();

    return 0;

}

PRACTICAL –  5.2

Write a function that creates a vector of user given size M using new operator. Demonstrate the use of the function.

#include <iostream>

using namespace std;

class Complex

{

    int real, imaginary;

public:

    void getData()

    {

        cout << "The real part is " << real << endl;

        cout << "The imaginary part is " << imaginary << endl;

    }

    void setData(int a, int b)

    {

        real = a;

        imaginary = b;

    }

};

int main()

{

    Complex *p = new Complex;

    p->setData(11, 12);

    p->getData();

    return 0;

}

PRACTICAL – 5.3

Write  a  C++  program  to  swap  two  number  by  both  call  by  value  and  call  by  reference mechanism, using two functions swap_value() and swap_reference respectively , by getting the choice from the user and executing the user’s choice by switch-case.

#include <iostream>

using namespace std;

class Swap

{

public:

    void swap_value(int a, int b)

    {

        int temp = a;

        a = b;

        b = temp;

        cout << a << endl

             << b;

    }

    void swap_refrance(int *a, int *b)

    {

        int temp = *a;

        *a = *b;

        *b = temp;

    }

};

int main()

{

    Swap r;

    int num1, num2, selaction;

    cout << "Enter two Numbers : ";

    cin >> num1 >> num2;

    cout << "Enter Selaction  " << endl

         << "1. Value swap " << endl

         << " 2. Refrance swap " << endl;

    cin >> selaction;

    switch (selaction)

    {

    case 1:

        r.swap_value(num1, num2);

        break;

    case 2:

        r.swap_refrance(&num1, &num2);

        cout << num1 << endl

             << num2;

        break;

    default:

        cout << "Wrong Input";

        break;

    }

    return 0;

}
