c++ 4.3.2 never heard of that in my life and you can't be asking for a new c++ that's just like asking for a new english language.
C++ is the programming language itself. I assume you mean you want a new compiler/IDE to program your c++ code.
The 3 ost common and popular ones are
1. Visual c++ express edition (free version)
2. Code::Blocks
3. Dev C++
Dev C++ is done production so it is now outdated.
Visual c++ is by far the best but it has a more professional layout because that's what the professionals use. Code::Blocks is a more simpler layout and can still get the job done but visual c++ has a much better debugger which could be very valuable when creating large programs.
I use visual c++ and code::blocks so either one is good
You can find visual c++ on the microsoft website. Just search for visual c++ on google and code::blocks is on the official code::blocks website and you can search that up on google also.
Note that if you download code::blocks then download the one with MinGW. It has a lot of extra features and is needed if you're going to do some type of graphics programming like games.
You could also use eclipse like the person above me said but eclipse is more of a java compiler so I would rather use 1 of the 2 i've mentioned.
Hope This Helped :D
