/* The <assert.h> header contains a macro called "assert" that allows 
 * programmers to put assertions in the code.  These assertions can be verified
 * at run time.  If an assertion fails, an error message is printed.  
 * Assertion checking can be disabled by adding the statement
 *
 *	#define NDEBUG
 *
 * to the program before the 
 *
 *	#include <assert.h>
 *
 * statement.
