Why is it OK to return a 'vector' from a function?
...
Pre C++11:
The function will not return the local variable, but rather a copy of it. Your compiler might however perform an optimization where no actual copy action is made.
See this question & answer for further details.

Exotic architectures the standards committees care about
I know that the C and C++ standards leave many aspects of the language implementation-defined just because if there is an architecture with other characteristics, it would be very difficult or impossible to write a standard conforming compiler for it.

Object-orientation in C

Now I pity C++... Well of course the C++ syntax is clearer, but since it's not a trivial syntax, I'm mitigated. I wonder if something hybrid between C++ and C could be achieved, so void* would still be valid castable type. The part with...
What is __gxx_personality_v0 for?
...r question. As mentioned on that answer, its use is defined by the Itanium C++ ABI, where it is called the Personality Routine.
The reason it "works" by defining it as a global NULL void pointer is probably because nothing is throwing an exception. When something tries to throw an exception, then y...
How do I read an entire file into a std::string in C++?
...ndant copies is to do the reading manually in a loop, unfortunately. Since C++ now has guaranteed contiguous strings, one could write the following (≥C++14):
auto read_file(std::string_view path) -> std::string {
constexpr auto read_size = std::size_t{4096};
auto stream = std::ifstream...
Cannot find Dumpbin.exe
...perly. Look for an icon in the start menu that says something like "Visual C++ 2005 Command Prompt". You should be able to run dumpbin (and all the other command line tools) from there.

print call stack in C or C++
Is there any way to dump the call stack in a running process in C or C++ every time a certain function is called? What I have in mind is something like this:

“static const” vs “#define” vs “enum”
...hink harder if you need to satisfy both at once.
If you were asking about C++, then you'd use option (1) — the static const — every time.
