Usage of Hex Dump in C++ Programming

[Matt]

I want to know what is Hex Dump? I tried to search in google but
didn't get useful results. I know it is the hexademical representation
of something. But I don't know what is something? From C++
programmer's perspective, I always hear this term. But when do we need
to use hex dump? what's the importances of hex dump?

please advise. thanks!!

Someone answered your question in the comp.lang.c group.. check that
one out!

I suppose its a (fairly) convienent way of examining the contents of a
binary file. It's got nothing to do with C++ at all, and you must be
moving in unusual circles if you always hear the term in connection with
C++.

Everything!
And that is because everything in a computer is just a number. Be it
programs, be it text, be it pictures, be it ...
When you look at the things at the machine level then everything is
just a number. And this number can be represented in hex. Why hex?
Well. Because most computers have a byte size of 8 bits. Which converts
easily and nicely into hex. Each nibble (4 bits) is a single hex digit.
