64-bit computers have been around and well for a long time already. Most applications have 64-bit versions that can benefit from larger memory capacity and improved performance thanks to the architectural capabilities of 64-bit processors. Developing 64-bit application in C/C++ requires much attention from a programmer. There is a number of reasons for 32-bit code to fail to work properly when recompiled for the 64-bit platform. There are a lot of articles on this subject, so we will focus on some other thing. Let's find out if the new features introduced in C++11 have made 64-bit software programmers' life any better and easier.
