1 Appendix A C++ Operators The relative precedence of the operators is shown, in decreasing order, in Table A.I where operators with the same precedence appear in the same "box". In the "example" column, exp stands for "expression", lvalue denotes an expression yielding an lvalue and explist stands for a comma-separated list of expressions.

3 AppendixB The String Class The string class is actually an instance of the more general basic_string class template which takes three template arguments. The CharT type specifies the underlying type of character; a basic_string represents a sequence of such CharT objects. The Trai t s type specifies a number of properties of the CharT type, e.g. the "end of string" character, CharT comparison and conversion operations, etc. The Alloc parameter specifies a class that provides memory management services for the allocation of basic_string objects. For the string class, the parameters are instantiated as shown below. typedef basic_string<char,chaltraits<char>,allocator<char> > string; typedef basic_string<wchar_t,char_traits<wchar_t>,allocator<wchar_t> > wstring; The allocator<char> type is an instance of the standard system-provided allocator class template (see e.g. [Str97], page 567). Wstring is the equivalent of string for "wide" characters (see Section 2.1). tempiate<typename CharT, typename Traits, typename Alloc> class basic_string { public: typedef Traits traits-type; typedef typename Traits::char_type value_type; typedef Alloc allocatoltype; typedef typename Alloc::size_type size_type; II size of string type static const size_type npos = static_cast<size_type>c-1); II maximum size of a string typedef typename Alloc::difference_type difference_type; typedef typename Alloc::reference reference; typedef typename AlJoc::consLreference conslreference; typedef typename Alloc::pointer pointer; typedef typename AlJoc::consLpointer conslpointer; 267
