Every commercial compiler comes with a reference manual. Often, it
is electronic. You need to check your compiler packaging. If you
decided to get a free compiler off the net somewhere, you should
probably turn your sights to another form of the reference manual,
like a web-based one (msdn2.microsoft.com for Microsoft compilers,
for example).
That said, you won't get much help on _how to use_ 'cin' because
what you looking for is not in a reference manual. They would just
tell you that 'std::cin' is an object of type 'std::istream'. Now,
how do you use that? You'd need to look for 'std::istream' and all
related stuff. And then you'll be making guesses or looking at
their [often riddled with errors] "examples". It's just not a good
use of a reference manual.
Get yourself a copy of a decent C++ learning book, *like* the
"Accelerated C++" by Koenig and Moo. And *study*.
