Detailed Description

Determine the symmetry of trap patterns.

Determine the symmetry of trap patterns. That is, determine the number of non-winning patterns, the number of 0-symmetrical patterns, the number of 2-symmetrical patterns, the number of 4-symmetrical patterns, and the number of 8-symmetrical patterns.

Function Documentation

static void _interrupt (  int  sig  )  [static]

If this program receives a SIGINT, then print out the current totals. Parameters: sig  int : signal number. Returns: void.

static void _make_move (  int  pos  )  [static]

This routine does most of the work of determining the symmetry of trap patterns. Parameters: pos  int : offset in plain to make move. Returns: void.

static int _revolve (  int  iplain  )  [static]

Revolve a plain 180 degrees about a diagonal axis. Returns: int : plain that has been revolved 180 degrees about a diagonal axis.

static int _rotate (  int  iplain  )  [static]

Rotate a plain 90 degrees. Returns: int : plain that has been rotated 90 degrees.

main (  void   )

Determine the symmetry of trap patterns. Returns: int.
