Write a C program to print n terms of Fibonacci series

Definition of Fibonacci numbers:

We assume first two Fibonacci are 0 and 1

A series of numbers in which each sequent number is sum of its two previous numbers is known as Fibonacci series and each numbers are called Fibonacci numbers. So Fibonacci numbers is

Algorithm for Fibonacci series 

F_n = F_n-2 + F_n-1

Example of Fibonacci series:

0 , 1 ,1 , 2 , 3 , 5 , 8 , 13 , 21 , 34 , 55  ...

#include<stdio.h>

int main(){

    int k,r;

    long int i=0,j=1,f;

    //Taking maximum numbers form user

    printf("Enter the number range:");

    scanf("%d",&r);

    printf("FIBONACCI SERIES: ");

    printf("%ld %ld",i,j); //printing first two values.

    for(k=2;k<r;k++)

    {

         f=i+j;

         i=j;

         j=f;

         printf(" %ld",j);

    }

  

    return 0;

}

Sample output:

Enter the number range: 15

FIBONACCI SERIES: 0 1 1 2 3 5 8 13 21 34 55 89 144 233 377
