where is header file

This function does not require a header file. Besides, it is a code snippet and not a complete application. You will have to call it from main() or any other function to use it.

Oh, come on! It can be done, in one line! int fibonacci(int number){ return number

int fibonacci(int number){ return number

:S

int fib(int x) { if (x==0) return 0; else if (x==1) return 1; else return fib(x-1)+fib(x-2); }

Fn=0 za n= 0; Fn=1 za n= 1; Fn=Fn–1+ Fn–2 za n>=2;

what is the header to run this codes int fib(int x) { if (x==0) return 0; else if (x==1) return 1; else return fib(x-1)+fib(x-2); }

also use "static int"for f1 and f2

regular c header.....stdio.h or iostream for c++

how can I write fibonacci with arrays?

what if x = 2 which in fibonacci is also 1.you just give the condition if x = 1?
