WWDC 404 Fibonacci example in C

fibonacci.c

long fibonacci(long n)
{
	return n < 2 ? n : fibonacci(n - 1) + fibonacci(n - 2);
}


int main(int argc, char const **argv)
{
	double phi = fibonacci(45) / (double)fibonacci(44);
	
	return 0;
}

this is a similar one in go

package main

import "fmt"

func fibonacci(n int64) int64 {
    if n < 2 {
        return n
    } else {
        return fibonacci(n-1) + fibonacci(n-2)
    }
}

func main() {
    var a int64 = 45
    var b int64 = 44

    fmt.Println(float64(fibonacci(a)) / float64(fibonacci(b)))
}
