QUESTION:

 

Define a class Cat having attributes

1. name (char *)

2. weight (double )

Now do the following operations on above mentioned class:

·         Write default constructor, parameterized constructor.

·         Write a display() function to display attributes of class Cat on screen.

Solution

 

#include <iostream>

#include <string>

using namespace std;

class Cat

{

public:

            string name;

            double weight;

            Cat()

            {

                        name = '\0';

                        weight = 0.0;

            }

            Cat(string n, double w)

            {

                        name = n;

                        weight = w;

            }

            void Setname(string n)

            {

                        name = n;

            }

            void Setweight(double w)

            {

                        weight = w;

            }

            string Getname()

            {

                        return name;

            }

            double Getweight()

            {

                        return weight;

            }

            void display()

            {

                        cout << "\n\n\t --RESULT--\n";

                        cout << "  Name of Cat:  " << name << endl;

                        cout << "  Weight of Cat:  " << weight << endl<<endl;

            }

};

int main()

{

            Cat obj;

            string a;

            double b;

            cout << "Enter Name of Cat: ";

            cin >> a;

            cout << "Enter weight of Cat: ";

            cin >> b;

            obj.Setname(a);

            obj.Setweight(b);

            obj.display();

            system("pause");

            return 0;

}
