Binary tree in C - Page 2

change "char c" to "int c", and life should be beautiful...

why does this work... i mean it starts reading but it doesn't end. Will it find the EOF character ?

on some examples it doesn't work... it segm faults!

I see this is for a huffman tree(of which there are different compressions); when I created a huffman encoder/decoder (in c++) I found it almost essential to create a bit stream class (although you could use structs for the same purpose). Just thought I would throw this idea out there, as it makes reading and writing huffman codes far easier

dmail i must use C not C++. Can you detaliate your ideea ?

Maybe it would be better if you could see the code first, have a look at
http://linux_questions.pastebin.com/680740 and
http://linux_questions.pastebin.com/680741

This code could then be changed to be standard C using a struct instead of a class (as OO is sortof possible with C, it's just that it's more difficult as it's not an OO language, but structs are not that far from classes).

Any "C++ idea" can be reasonably implemented in C using an agreed-upon data structure that is passed to each routine. The routines outside of the implementing unit can treat it as a "void pointer."
