USING CUDA WITH C++ SYNTAX

How can we write C++ codes in CUDA environment.

Or

if I want to write C++ Parallel Codes with CUDA what I will Use

Actually I wanted to do write a parallel program in cuda environment but the same code can be very small if I use C++ codes or object oriented concepts.

… Thanks

Your question is beyond vague. You can for the most part mix C/C++ and CUDA, with some exceptions. CUDA is a subset of C language, parsed through NVIDIA nvcc compiler. Read wikipedia, download the SDK, and read the documentation and look over the very many samples it encloses.
