C++中函数指针的用途非常广泛，例如回调函数，接口类的设计等，但函数指针始终不太灵活，它只能指向全局或...
std::put_time()andstd::get_time()are part of C++11 and defined in<iomanip>. This header is included in the cron header: #include<vector>#include<string>#include<sstream>#include<bitset>#include<cctype>#include<ctime>#include<iomanip>#include<algorithm> As far as I can figure out, suppo...

I want understand how to work std::put_time, and how can I get date stamp in "YYYY/MM/DD HH:MM:SS" format. Now I write somthing like this: std::chrono::time_point<std::chrono::system_clock> now = std::chrono::system_clock::now(); std::time_tnow_c = std::chrono::system...
在 C++ 编程中，有时候我们需要在不进行拷贝的情况下传递引用，或者在需要引用的地方使用常量对象。为了...

time_put::puttime_put::do_put Defined in header <locale> protected: ~time_put(); Destructs a std::time_put facet. This destructor is protected and virtual (due to base class destructor being virtual). An object of type std::time_put, like most facets, can only be destroyed when th...
