FIBONACCI SERIES – HSC FAVORITE QUESTION

NOW WHAT IS FIBONACCI SERIES….

0,1,1,2,3,5,8,13……..

followed the trend???Noo??

A series of number in which each number is the sum of preceding two numbers is known as Fibonacci series.
This is a very important and the most asked question of HSC.

#include<iostream.h>

#include<conio.h>

void main()

{

clrscr(); \\clears the previous output

int a=0, b=1, n, c;   \\first two numbers of fibonacci series is 0 and 1

cout<<“Enter the number of terms till you want fibonacci series”;

cin>>n;

\\User choice, till wherever he wants to print the series

cout<<a<<“\t”<<b;

for(int i=1; i<=(n-2);i++)    

       \\ you must be thinking why (n-2), its because first two terms i.e 0  and 1  are already included

{

  \\it’ll print 0 and 1 which is first two numbers

cout<<a<<“\t”<<b<<“\t”;    

       \\now as we go by definition fibonacci series is evaluated by adding the                                    previous two numbers….here that number is c

c=a+b;

         
cout<<c;

b=c;                    \\now upgrade the values of variable…. think yourself y

a=b;

}

getch();
