Thread: Compilation Error. Need help

Ok. I'm doing a Towers of Hanoi project and it's supposed to be a multi file program. I keep getting this error and I can't figure out why.
hanoi.c:4: error: redefinition of ‘hanoi’
hanoi.h:5: error: previous definition of ‘hanoi’ was here
Here's the code for hanoi.h

Code:

void makeMove(int, int);
void hanoi(int, int, int, int);


extern in n;
extern int noOfMoves;
enum stacks{A = 1, B, C};

and for hanoi.c

Code:

#include "hanoi.h"

void hanoi(int n, int src, int dest, int by)
{
        if(n == 1)
        {
                makeMove(src, dest);
        }
        else
        {
                hanoi(n - 1, src, by, dest);
                makeMove(src, dest);
                hanoi(n-1, by, dest, src);
        }
}
