A recent Visual C++ team’s comment on twitter.com reminded me a hot topic that exists in C++ programming world: there is a long discussion of using pre versus post increment operators, specially, for iterators. Even me I was witness to a discussion like this. The discussion started from a FAQ written by me on www.codexpert.ro.

Base on that VC++ team’s tweet related to viva64.com’s research I decided to create my own benchmark base on single and multicore architectures. For those that don’t know Viva64 is a company specialized on Static Code Analysis.
Starting from their project I extended the tested for other STL containers: std::vector, std::list, std::map, and std::unordered_map (VC++ 2010 hash table implementation).
For parallel core tests I used Microsoft’s new technology called Parallel Pattern Library.

In our real applications we have to convert from strings to integer or to real variables and vice versa (double/float/int variable to std::string).
We can realize these conversions using C style CRT function or we can try C++ approach via STL.

Many applications allow dynamic customization for visual objects or data views. For instance, well known Internet Explorer application provides toolbars customization using a popup menu that appears when the user execute right click mouse action in toolbar zone area.

Other sample where this kind of menu is very useful is when it’s used in order to customize database data representation in Windows controls like List control or grid control. These kind of applications allow data filtering and show/hide columns using this kind of menu. The user just right click on control header and gets what he need.
