overloading std::string operators requires template<> syntax ! Howto ? Jul 12, 2012 at 6:29pm lalebarde(114) Hi all, I need to overload a cast to u_int32_t of std::string. I wrote this : string::operatoru_int32_t()const{return0;} ...
These operators are declared in the namespacestd::literals::string_literals, where bothliteralsandstring_literalsare inline namespaces. Access to these operators can be gained with either usingnamespacestd::literals, or usingnamespacestd::string_literals, or ...
std::string简介及其使用 注:std::string C++11标准。 string概述 typedef basic_string<char>string; 字符串是表示字符序列的对象。 标准string类使用类似于字节标准容器的接口提供对此类对象的支持,但是添加了专门用于操作单字节字符(single-byte characters)的字符串的特性。 string类是basic_string类模板的实例化,该...
std::string m_value; // ctors and operators public: CVariable (const int p_flags = 0); CVariable (CVariable&, const int); CVariable (std::string const&, const int); CVariable (const int&, const int); CVariable (const float&, const int); CVariable& operator= (const CVariable&)...
Fortunately, for C++ strings, all of the typical relational operators work as expected to compare either C++ strings or a C++ string and either a C string or a static string (i.e., "one in quotes"). For instance, the following code does exactly what you would expect, namely, it ...
Furthermore, many of the intuitive operators that C provides to work with numbers, such as assignment and comparisons, simply don’t work with C-style strings. Sometimes these will appear to work but actually produce incorrect results -- for example, comparing two C-style strings using == wil...

operators for lexicography compare:==, !=, <=, >=, <, > operator << One important note is that all of the above methods (except forcopyandoperator <<) are alsoconstexpr! With this capability, you might now work with strings in constant expressions. ...
std::locale::name() returns std::string by value, so to compile std::locale, the compiler must see the class definition (but not the non-member operators such as I/O) of std::string. Just to appreciate the complexity behind the scenes, in dinkumware-derived libraries (IBM, and I beli...
