Functions
void	PrintFileReadError (int errorType)
	It prints an error related to the data file input.
void	IncArraySize (int *&array, int oldSize, int newSize)
	It resizes the array to have an increased size.
bool	CollectBinaryInfo (char *filename, int &custCount, int &itemCount, int &transCount, int *&custTransCount, int *&itemCustCount, int *&cids, int *&tids, int *&iids, int *&transLens, int &overallCount, int &transLensLength)
	It collects information about a binary data file.
bool	CollectASCIIInfo (char *filename, bool isStringFile, StringMap *&custStrMap, StringMap *&transStrMap, StringMap *&itemStrMap, int &custCount, int &itemCount, int &lineCount, int *&custTransCount, int *&itemCustCount, int *&cids, int *&tids, int *&iids, int &overallCount)
	It collects information about an ASCII data file.
bool	ReadBinary (char *filename, int *cids, int *tids, int *iids, int numEntries, int *transLens, int transLensLength, int *custBitmapMap, int **custMap, int *itemMap, SeqBitmap **f1Buff)
	It reads stores the binary data file.
bool	ReadASCII (char *filename, int *cids, int *tids, int *iids, int numEntries, int *custBitmapMap, int **custMap, int *itemMap, SeqBitmap **f1Buff)
	It reads stores the ASCII data file.
DatasetInfo *	ReadDataset (bool isBinaryFile, bool isStringFile, char *filename, double minSupPercent, StringMap *&custStrMap, StringMap *&transStrMap, StringMap *&itemStrMap)
	It reads the input file and finds the frequent-1 itemsets.
Variables
const int	NUM_BITMAP = 5
	number of different bitmaps in SeqBitmap
const int	BITMAP_LENGTH [5]
	the size of each customer data in each bitmap
const int	NUM_BITMAPS_USED = 4
	tempAndBitmap, specialBitmap, returnBitmap, SBitmap
const int	MAX_STRING_SIZE = 256
	Maximum length of strings used to represent customers, transactions, and items when -str is used.
