A hex dump *does* convert a binary into text. What did you think a hex
dump does?

Your indentation is messed up. I suspect that you're indenting with
a mix of spaces and tabs, and the tabs are getting lost somewhere
between your news client and mine. Figure out how to indent with
spaces only, at least for code you post. (Filtering through the Unix
"expand" command is one way to do this.)

For a do-while loop, it's clearer to put the while on the same line as
the "}"; otherwise it looks very much like a while loop.

There are numerous other problems with your code.
As you should realize by now, just getting a C program to compile
doesn't imply that it's going to work. There are other languages
where code that just compiles is more likely (though by no means
certain) to work correctly. (Python springs to mind.) Of course you've
been offered this advice before.
