Text Compression Utility in C++.

implementing a compression utility for ASCII-encoded text.

Your program should be able to both compress and decompress text files, computing the

compression ratio and the efficiency of your encoding. The steps to implement this program

are as follows:

1. Determine the symbols / characters used in the file, build your alphabet and probabilities

2. Build a merge tree to find the optimal coding for each symbol

3. Encode your characters with the new binary codes

4. Save the coded characters along with your code table in the output compressed file

For decompression, your program should read the code table / tree from the compressed file

and use that to recover the originally compressed text file.

Optimally, your program should have three different parameters passed to it at runtime:

1. A flag indicating whether it is being used to compress or decompress the input file

2. The path of the input text file

3. The path to write the output file (compressed file in case of compression, text file in case

of decompression)

When used for compression, your program should output the compression ratio (for ASCII encoded files where each character is written in 8 bits, the compression ratio will be <L> / 8)and the efficiency (η) of your encoding

Hi, I already have a text compression program in C++. It uses Huffman coding. I am not sure if that is exactly what you need. But if it is I can sell it to you. Please let me know,
