Since I'm lazy, and only need decomp (which seems to be easier anyway), I only wrote that. Unfortunately I do not have a matching decoder to offer. inserting new characters into the front of

Is there a reason why you can't step through the code with a debugger to see why those characters are skipped? &out_counter, out_file_desc);

In most cases we don't get that far, actually, most of the times we won't get passed the 16 bit barrier (which gives us 65,535 possible entries in the dictionary). The static compression is when we use a static number of bits to make the compression.

In other words, if your statement that "my compression works" actually means "it reduces your size", and that's it, you shouldn't rule out a bug in that code just yet. string_table[258].num = 256;

----- This tool generate compression and decompression using LZ-77, LZ-78 and LZW methods : 1- LZ-77 2- LZ-78 3- LZW Enter 1, 2 or 3 according to method. Initially, stack_pointer = -1.
The dynamic compression changes the number of bits used to compress the data. displacement = lseek(in_file_desc, 0L, 0);
We flash the end after the m_MaxCode[m_MaxBits] with '0' to make sure that the file will contain all the code.
