fibonacci series using recursion in c program code example

Example 1: fibonacci series in c using recursion in data structure

#include<stdio.h>
int f(int);
int main()
{
int n, m= 0, i;
printf("Enter Total terms:n");
scanf("%d", &n);
printf("Fibonacci series terms are:n");
for(i = 1; i <= n; i++)
{
printf("%dn", fibonacci(m));
m++;
}
return 0;
}
int fibonacci(int n)
{
if(n == 0 || n == 1)
return n;
else
return(fibonacci(n-1) + fibonacci(n-2));
}

Example 2: fibonacci recursion c

#include <stdio.h>

int factorial(int n) {
   //base case
   if(n == 0) {
      return 1;
   } else {
      return n * factorial(n-1);
   }
}

int fibbonacci(int n) {
   if(n == 0){
      return 0;
   } else if(n == 1) {
      return 1;
   } else {
      return (fibbonacci(n-1) + fibbonacci(n-2));
   }
}

int main() {
   int n = 5;
   int i;
	
   printf("Factorial of %d: %d\n" , n , factorial(n));
   printf("Fibbonacci of %d: " , n);
	
   for(i = 0;i<n;i++) {
      printf("%d ",fibbonacci(i));            
   }
}
