就像std::string一样,大家还是会有自己的第三方string。第三方string也会提供form_string和to_string的接口,转换更方便。《Dicrection for ISO C++》中列举了未来C++标准库的重点发展方向,其中第二条就是Linear algebra,主要是为图形学和机器学习提供基础设施,如果有自己干兴趣
int fwprintf( std::FILE* stream, const wchar_t* format, ... ); (2) int swprintf( wchar_t* buffer, std::size_t size, const wchar_t* format, ... ); (3) Loads the data from the given locations, converts them to wide string equivalents and writes the results to a ...
The full conversion specification must be %%. N/A N/A N/A N/A N/A N/A N/A N/A N/A c Writes a single character. The argument is first converted to unsigned char. If the l modifier is used, the argument is first converted to a character string as if by %ls with a ...
struct full_extent_t { explicit full_extent_t() = default; }; (1) (since C++26) inline constexpr std::full_extent_t full_extent {}; (2) (since C++26) 1) The class std::full_extent_t is a slice specifier type that can be used in std::submdspan.2...

C++ standards in Microsoft Visual C++ compilers c++ use an image as the background. C++ When my code asks for my full name it only gets my first name and not last C++/CLI DLL referencing MFC: mfcs140d.lib(dllmodul.obj) : error LNK2005: DllMain already defined in msvcrtd.lib(dll_dllmai...
There is one important subtlety here. If the argument is a temporary object (that will be destroyed at the end of the full expression containing the function call), thestd::string_viewreturn value must be used in the same expression. After that point, the temporary is destroyed and the std...
See more at Cppreference - decltype. Inside the function, we use a fold expression (available since C++17) to expand this variadic parameter pack over a comma operator. In other words our function will instatiate to the following form: void printTupleManual<std::tuple<int, int, const char...
All in all, I don't see it replacing std::filesystem where full C++17 or C++20 is available, it doesn't try to be a "better" std::filesystem, just an almost drop-in if you can't use it (with the exception of the UTF-8 preference)....
Debugger show full stack calls, but std::stacktrace_entry sequence don’t include it. Minimal complete code is (compiled with «cl -EHa -std:c++latest -Zi -Od delMe.cpp» from console): #include <windows.h> #include <functional> #include <stacktrace> #include <st...
