fibonacci series in c using function | Display Fibonacci series in C within a range using a function 

1. 
   

Enter range: 20

The fibonacci series is:

0 1 1 2 3 5 8 13

fibonacci series in c using for loop 

#include<stdio.h>
#include<conio.h>

int main ()
{

int first = 0, second = 1, third, i, n;

printf ("Enter the length of the fibonacci series \n");
scanf ("%d", &n);

printf ("The Fibonacci series is :\n");

printf ("%d%d", first, second);

for (i = 2; i <= n; i++)

{

third = first + second;

printf ("%d ", third);

first = second;

second = third;

}

return 0;

}

 OUTPUT:

Enter the length of the fibonacci series
