Calculating Fibonacci Numbers Recursively in C

Question

I\'m trying to learn C by writing a simple program to output Fibonacci numbers. It isn\'t working.

fibonacci.h

unsigned int fibonacc         


        

Answer 1

You need \n not %n for your printf. Also, you can simplify as:

#include "fibonacci.h"

unsigned int fibonacci_recursive(unsigned int n) {
if (n < 2) 
    return n;
else
    return fibonacci_recursive(n - 1) + fibonacci_recursive(n - 2);
}
