[yakir a. <ya...@za...>]

Hi verne
Thanks for the book man
Only problem is,I don't know with what I should open the book[.pdf],what
does it mean?
I tried opening it with notepad,but it just shos ya a lot of numbers and
simballs,and not the book it self
Can you tell me how should I open it
And do you think I should leav my current book I'm reading now "teach
your self c++ in 21 days"?
Thanks
