I am an intermediate c++ programmer. I want to make program on LZW compression technique using c++. Please point me to the right direction.
Like i don't know how to access the binary code of a .gif file in c++ program
 
File I/O in C++.
Input/Output with files

parameters required for opening the file will be ios::in and ios::binary.
Once you have the file opened in binary format, you'll need this for understanding the binary data.
File format of a .gif file.
Graphics Interchange Format - Wikipedia, the free encyclopedia
GIF format

You will need an LZW decompression code to extract data from the gif file. There are many examples available on the net in multiple languages for both encoding and decoding using LZW algorithm.
