I used G++ for a long time, now I decided to migrate to Visual C++ but codeforces don't has support for Visual Studio 2012. That is a trouble cause the C++ 11 standard is under implementation for VS and we can find many differences between VS2010 and VS2012. I wonder if would be to risky to write code in my VS2012 and send it for the VS2010 compiler. Any experience will be welcome. Thanks.
BTW If you'll write code in exactly the same way as you did using g++ you may submit under g++ even if you write it in VS
you are right, i can use the same code style as always but you don't know when a new feature would be useful and those compilers aren't 100% compatible. One reason is that both implement only one part of the c++11 standard, so if i want to use some new feature available in VS2012 compiler, is not easy to know during a contest if that feature is available in VS2012 or g++. I believe that adding support for the VS2012 compiler is a good idea.
Better idea is to add support for VS2013 compiler when it will be released (probably in this October), because it almost completely supports C++11 standard and STL in contradistinction to VS2012 even with November compiler pack.
