#include<iostream>

#include<conio.h>

using namespace std;

void fibonacci_Series(int length);

int main()

{

       int series_length = 0, temp = 0;

       cout << "\n\t ______ Program to print Fibonacci Series ______";

       cout << "\n\n  Enter the Length of the Series - ";

       cin >> series_length;            

       fibonacci_Series(series_length);

       getch();            

       return 0;    

}

void fibonacci_Series(int length)

{

       int first_number = 0, second_number = 0, third_number = 0, temp = 0;

       first_number = 0;   

       second_number = 1;

       cout << "\n\n  Fibonacci Series  -  " << first_number << " , " << second_number;

       for(temp = 3; temp <= length; temp++)

       {

              third_number = first_number + second_number;

              cout << " , " << third_number;

              first_number = second_number;

              second_number = third_number;

       }
