Can't build CUDA Test Application

Currently following the CUDA Getting Started guide for Microsoft Windows [ http://docs.nvidia.com/cuda/cuda-getting-started-guide-for-microsoft-windows/index.html ]; installed CUDA; the samples and NSight; im on Visual Studio 2010; I have checked my card and it supports CUDA. I followed the tutorials up to the demo parts... but I am getting the following error message:

I acknowledge that cin is part of iostream which i have verified is part of my include directive in my code...

I am coming from a web developer's background; I rarely program these types...

I'm assuming you've modified the bandwidthTest.cu file and this is not the vanilla SDK sample (since a quick check shows it doesn't use cin by default!).

You either need to use std::cin to explicitely state the scope or add a using namespace std or using std::cin to either the top of your file (after including iostream) or the top of the function.

Searching for info on namespaces should give more background, e.g. this tutorial.

If this isn't the problem, then post some code.

Update

From your it seems comment, your real question is how to create a CUDA project in VS2010. See this answer for information on that! Basically you need to create .cu files in your project and then tell Visual Studio what to do with them (i.e. enable the build customisation).
