How does c++ (c++0x) handle implicitly typed variables?

Question

I am trying to learn how to use implicitly typed variables in c++.

Should i be using 'auto' from C++0x? If so how?

Can some one provide me with a simple example or a good tutorial on this?

Thank you.

Look for discussion of the `var` keyword in C#; a lot of the arguments for and against will be the same. — Niall C., May 27 '10 at 21:33

Check out this explanation from Bjarne Stroustrup himself: auto -- deduction of a type from an initializer.

auto x = f();

The type of x will be whatever f() returns.

also x has to be cast back into the type f() returns :) – LoudNPossiblyWrong May 28 '10 at 04:10

@LoudNPossiblyRight: I have no idea what you are trying to say. (Whatever interpretation I can come up with seems wrong.) – sbi May 28 '10 at 10:10
