FIBONACCI SERIES using CONSTRUCTOR

8. Write a Program to generate Fibonacci Series by using Constructor to initialize the Data Members.

// FIBONACCI SERIES using CONSTRUCTOR

#include<iostream>

 #include<iomanip>

class fibonacci 

{

            int n1,n2;

public:

            fibonacci()

            {

            }

            void series(int);

};

void fibonacci::series(int n)

{ 

            int i,next;

            cout << setw(4) << n1 << setw(4) << n2;

            for(i=1; i <= n-2; i++)

            {

                        next = n1 + n2;

                        cout << setw(4) << next;

                        n1 = n2;  n2 = next;

            }

}

            int n;

            cout << "FIBONACCI SERIES\n";

            cout << "How many numbers? ";
