std::put_time 转string 文心快码BaiduComate 为了将std::tm结构体实例格式化为字符串,并存储到std::string中,你可以按照以下步骤操作: 1. 引入必要的头文件 为了使用std::put_time和相关的功能,你需要包含<iomanip>和<ctime>头文件。此外,为了处理字符串,你还需要包含<sstream>和<...
When used in an expression out << put_time(tmb, fmt), converts the date and time information from a given calendar time tmb to a character string according to format string fmt, as if by calling std::strftime, std::wcsftime, or analog (depending on CharT), according to the std::...

explicit time_put_byname( const std::string& name, std::size_t refs = 0 ); (since C++11) Constructs a new std::time_put_byname facet for a locale with name. refs is used for resource management: if refs == 0, the implementation destroys the facet, when the last std::locale ...
