#include <stdio.h>

int main (void)

{

               int terms;
               int previous, current, next;
               int i;

               //Input number of terms.
               printf ("Input number of terms: ");
               scanf ("%d", &terms);

               //Printing the Fibonacci Series.
               previous = 0;
               current = 1;
               printf ("%d terms of Fibonacci Series: %d  %d  ", terms, previous, current);

               //Finding the next term to print.

               for (i = 3; i <= terms; i++)
               {
                              next = previous + current;
                              printf ("%d  ", next);
                              previous = current;
                              current = next;
               }

               return 0;

};

Output

Input number of terms: 10
10 terms of Fibonacci Series: 0  1  1  2  3  5  8  13  21  34
