[Dev-C++] Hexadecimal Numbers

[Caroline T. <Car...@no...>]

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
