I follow the instruction and no I got another two errors for question 6.

here are the two errors

Severity Code Description Project File Line Suppression State Error (active) E0711 expression must have bool type (or be convertible to bool) DSA Labs C:\Users\donni\OneDrive\Desktop\DSA2\DSA Labs\DSA Labs\Huffman.h 324 Severity Code Description Project File Line Suppression State Error (active) E0135 class "Huffman::HuffNode" has no member "IsLeaf" DSA Labs C:\Users\donni\OneDrive\Desktop\DSA2\DSA Labs\DSA Labs\Huffman.h 334 Here is the heeder for the bitStream

class BitIfstream {

std::ifstream mStream; // The stream to use for inputting char mBuffer; // The current byte to read int mBitIndex; // The current bit in the buffer to read

public:

// Constructor // Will open the file and read the header (if there is one) // // In: _fileName The name of the file to open for input // _fileHeader Where to store the file header (OPTIONAL) // _headerSize The number of bytes in the optional header (OPTIONAL) BitIfstream(const char* _fileName, char* _fileHeader = nullptr, unsigned int _headerSize = 0);

// Destructor // Will close the file ~BitIfstream();

// Extraction operator // Sends back one bit from the buffer. Will read another char into the buffer once all // bits have been processed. // // In: _bit Where to store the bit // // Return: The invoking object // This allows extractions to be daisy-chained (standard behavior) BitIfstream& operator>>(bool& _bit);

// Check for End of File // // Return: True, if we are at the end of the file, having read every byte from the file and processed every bit bool eof();

// Close the file void Close();
