The std::string class is the standard representation for a text string since C++98. The class provides some typical string operations like comparison, concatenation, find and replace, and a function for obtaining substrings. An std::string can be constructed from a C-style string, and a C-style string can also be obtained from one. [7]
Provides a modern way of formatting strings including std::format. <string> Provides the C++ standard string classes and templates. <string_view> Added in C++17. Provides class template std::basic_string_view, an immutable non-owning view to any string. <regex> Added in C++11. Provides utilities for pattern matching strings using regular ...
Similar classes are also available through std::auto_ptr in C++98, and boost::shared_ptr in the Boost libraries. Also, messages can be sent to network resources using RAII. In this case, the RAII object would send a message to a socket at the end of the constructor, when its initialization is completed. It would also send a message at the ...
std::to_address to convert a pointer to a raw pointer [42] calendar and time-zone additions to <chrono> [43] std::span, providing a view to a contiguous array (analogous to std::string_view but span can mutate the referenced sequence) [44] std::erase and std::erase_if, simplifying element erasure for most standard containers [45] <version ...
C++11 is a version of a joint technical standard, ISO/IEC 14882, by the International Organization for Standardization (ISO) and International Electrotechnical Commission (IEC), for the C++ programming language. C++11 replaced the prior version of the C++ standard, named C++03, [1] and was later replaced by C++14.
In computer programming, lazy initialization is the tactic of delaying the creation of an object, the calculation of a value, or some other expensive process until the first time it is needed.
std::string_view, a read-only non-owning reference to a character sequence or string-slice [31] std::optional, for representing optional objects, a data type that may not always be returned by a given algorithm with support for non-return; std::any, for holding single values of any type; std::uncaught_exceptions, as a replacement of std ...
The variadic template feature of C++ was designed by Douglas Gregor and Jaakko Järvi [1] [2] and was later standardized in C++11. Prior to C++11, templates (classes and functions) could only take a fixed number of arguments, which had to be specified when a template was first declared.
