RE: [Dev-C++] Hexadecimal Numbers

[James G. <Jam...@Cl...>]

What is the actual headache?

Hex is only a way of displaying/storing numbers.
Humans use base 10 and so the numbers repeat at 10.
e.g. 1,2,3,4,5,6,7,8,9,10,11,12...
Hex is base 16 so the numbers repeat after 16 numbers.
e.g.
1,2,3,4,5,6,7,8,9,a,b,c,d,e,f,10,11,12,13,14,15,16,17,18,19,1a,1b,1c,1d,1e,1
f,20...

Regards,

James.

Help!! 
I'm working my way through a ' Teach yourself C ' book and have reached a
Chapter about Hex. 
I wondered if anyone knew where I could get further information on Hex, as
my book doesnt go into very much detail and it's making my head hurt!!!
Please email me at ' car...@no... '  with any links.
Cheers!
Caroline

Re: [Dev-C++] Win32 API

[Hoo H. <hoo...@ho...>]

hi,
  I just managed to find some references for Win32 API. Anyone interested
please check out this URL :
    http://www.mingw.org/docs.shtml
  Nevertheless, the best source for Win32 API is still MSDN.

Regards,
Hoo Hong

MSDN is great but where on it is it i found it once after like 3 hours but
cant again a link would be extremly helpful

[Dev-C++] Re: Hexadecimal Numbers

[Alan T. <ala...@3n...>]

"Hex" is a spell cast by an intelligent agent.  This sometimes affects the
execution of software by stealing clock cycles on the computer.

        Seriously . . . The hexadecimal system is a base 16 system, where
the decimal system is base 10.  This means that each digit can represent
0-15, as opposed to 0-9 in decimal.  After 9, of course, you need more
digits that don`t exist in base 10.  The letters "A" through "F" represent
the digit values 10 through 15.  Each digit is a power of 16, no longer a
power of 10, because this is a "base 16" system --- each digit can represent
one of 16 different values (0-15).
        So, the hexadecimal number      1C       converted to the decimal
system is 1x16^1 (16 to the first power) + Cx16^0 (16 to the zeroth power,
or 1),
which means 16 + 12 = 28.

        When you think about it, it's a lot like the decimal system, where
274 = 2x10^2 + 7x10^1 + 4x10^0.  It just seems weird because we have ten
fingers and normally use the decimal (base 10) system.  Binary works the
same way but in base 2 (only two values, 0 or 1, for each digit).


Hope this helps,   Alan

Re: [Dev-C++] Hexadecimal Numbers

[ropbert d b. <lon...@ju...>]

Hex is a different way of thinking. However, it is not that hard once you
understand the concept. Here is a good WEB site to help you.
http://www.phoenix.net/~jacobson/pages/hex.html
http://winnie.fit.edu/~emoore/hkbcheat.html   This is a good example site
http://www.hexworkshop.com/   This is a good HEX editor & converter

Good luck & if you need help we are here.
