C Program to Print Fibonacci Series Using Recursion

A series of numbers in which each number ( Fibonacci number ) is the sum of the two preceding numbers. The simplest is the series 1, 1, 2, 3, 5, 8, etc.

//C program to print Fibonacci series using recursion

#include<stdio.h>
 
int Fibo(int);
 
int main()
{
   int a, i = 0, c;
   printf(" enter number of elements wanted :");
   scanf("%d",&a);		// user input
   printf("Fibonacci series\n");
   for ( c = 1 ; c <= a ; c++ )
   {
      printf("%d\n", Fibo(i));	//calling the recursive function
      i++; 
   }
 
   return 0;
}
 
int Fibo(int a)					//recursive function Fibo
{						
   if ( a == 0 )
      return 0;
   else if ( a == 1 )
      return 1;
   else
      return ( Fibonacci(a-1) + Fibonacci(a-2) );
}
