The Slaying of The Turtle

Okay so my recent attempts to create this "turtle graphics" program hasn't gone too well. So I given up.

Okay so I haven't given up but I chose to postpone it until I know more about arrays, especially 2D ones. Thus I  have turned to Engineering Problem Solving with C (3rd Edition) and it's chapters on arrays.

I am about to begin work on a fun sounding "Terrain Navigation" exercise, simulating a robot navigating hills: the program will look at a 2D array and evaluate based on height information where peaks and valleys occur.

I'll post my progress later this evening if I do well!
