title: Explanation of CUDA C and C++
body: <p>Can anyone give me a good explanation as to the nature of CUDA C and C++? As I understand it, CUDA is supposed to be C with NVIDIA's GPU libraries. As of right now CUDA C supports some C++ features but not others. </p>
  
  <p>What is NVIDIA's plan? Are they going to build upon C and add their own libraries (e.g. Thrust vs. STL) that parallel those of C++? Are they eventually going to support all of C++? Is it bad to use C++ headers in a <code>.cu</code> file?</p>
