The class template basic_string stores and manipulates sequences of character-like objects, which are non-array objects of TrivialType and StandardLayoutType.The class is dependent neither on the character type nor on the nature of operations on that type. The definitions of the operations are supplied via the Traits template parameter - a specialization of std::char_traits or a compatible ...

c++ - std::wstring VS std::string - Stack Overflow

string? wstring? std::string is a basic_string templated on a char, and std::wstring on a wchar_t. char vs. wchar_t. char is supposed to hold a character, usually an 8-bit character. wchar_t is supposed to hold a wide character, and then, things get tricky: On Linux, a wchar_t is 4 bytes, while on Windows, it's 2 bytes. What about Unicode, then?

You won’t be working with this class directly, so don’t worry about what traits or an Allocator is for the time being. The default values will suffice in almost every imaginable case. There are two flavors of basic_string<> provided by the standard library: namespace std { typedef basic_string<char> string; typedef basic_string<wchar_t ...

The class template basic_string stores and manipulates sequences of char-like objects, which are non-array objects of trivial standard-layout type. The class is dependent neither on the character type nor on the nature of operations on that type. The definitions of the operations are supplied via the Traits template parameter - a specialization of std::char_traits or a compatible traits class.

basic_string - C++ Users

The basic_string is the generalization of class string for any character type (see string for a description). Template parameters charT Character type. The string is formed by a sequence of characters of this type. This shall be a non-array POD type. traits Character traits class that defines essential properties of the characters used by basic_string objects (see char_traits).

What You Need To Know About std::basic_string In Modern C++

What is basic_string? The basic_string (std::basic_string and std::pmr::basic_string) is a class template that stores and manipulates sequences of alpha numeric string objects (char,w_char,…). For example, str::string and std::wstring are the data types defined by the std::basic_string<char>.In other words, basic_string is used to define different data_types which means a basic_string is not ...
