C/C++ Struct vs Class
...ere was a difference in the first place long ago, back when C++ was still known as "C with Classes."
Note that C unions work with C++, but not the other way around. For example
union WorksWithCppOnly{
WorksWithCppOnly():a(0){}
friend class FloatAccessor;
int a;
private:
float b;
}...
In C/C++ what's the simplest way to reverse the order of bits in a byte?

Entity Framework Join 3 Tables
... used to call things really short names, but I can type plenty fast enough now (not even considering things like Intellisense) that the few characters saved is not worth the detriment in readability versus naming things verbosely e.g. "EntryID" vs. "EID", "combinedEntry" vs. "cm", etc. Eventually, s...
Why use #ifndef CLASS_H and #define CLASS_H in .h file but not in .cpp?
...rations for the code in class.cpp by including class.h. It only needs to know what these functions or variables look like (which is what a declaration gives you). So it compiles your main.cpp file into some object file (call it main.obj). Similarly, class.cpp is compiled into a class.obj file. T...
Threads vs Processes in Linux
...rsion ran about 9x faster (17.38 seconds for processes, 1.93 for threads). Now this does only test creation time, but for short-lived tasks, creation time can be key.

Is it possible to embed animated GIFs in PDFs?
... PDFs may have been originally made for physical printing, but have now completely taken the place of printed documents - they are the de-facto digital document, so it makes perfect sense that we should allow them to embed animations.
