how can I include <helper_cuda.h> to my cuda c project using vs 2013?
put
#include <helper_cuda.h>
at the top of any file where you want to use it.
Add the path to the samples directory to your project include path.
If you don’t know what the path to the file is, just use the windows search utility to locate the helper_cuda.h file. The path should end in …\common\inc
Take that path and add it to the project include paths.
Various cuda sample codes use this file, so you can also load one of those projects, and see how it is set up.
