Hey, I recently bought "Algorithms in C" by Robert Sedgewick

In his programms (Part 5) he refers to "graph.h"

On the website, I found an ftp Server with those files on it:

ftp://ftp.cs.princeton.edu/pub/cs226/map/c/

Now, I downloaded graph.h, graph.c, point.h, point.c, pqindex.h, pqindex.c from there.

I opened these in Dev-C++, and tried to compile "graph.c"...
