Differences between C++ string == and compare()?
...rested in how the two strings relate to one another" -- although idiomatic C++ for this is to use a strict weak order (like std::less, which is also a total order in this case) rather than a three-way comparator. compare() is for operations modeled on std::qsort and std::bsearch, as opposed to those...
Is there an online name demangler for C++? [closed]
...have created such an online serivice: https://demangler.com
This is a gcc c++ symbol demangler. You just copy a stack trace, or the output of nm into a text box, and it will return the output with the names demangled.
@Update: It now demangles MSVC and Java symbols also.

Iterate through a C++ Vector using a 'for' loop
I am new to the C++ language. I have been starting to use vectors, and have noticed that in all of the code I see to iterate though a vector via indices, the first parameter of the for loop is always something based on the vector. In Java I might do something like this with an ArrayList:
...
Difference between 'new operator' and 'operator new'?
...
new is not an operator in C++. sizeof, for example, is an operator, but new and delete are not. new and delete are keywords and the syntactical constructs that these keywords form are called new-expression and delete-expression.

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...
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...
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...
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.
