for defining the template class that serves as the base for many iostreams classes - for declaring several iostreams template classes before they are necessarily defined - for declaring the iostreams objects that manipulate the standard streams - for defining the template class that performs extractions - (STL) for defining several templates that help define and manipulate iterators - for testing numeric type properties - (STL) for defining a template class that implements a doubly linked list container - for defining several classes and templates that control locale-specific behavior, as in the iostreams classes - (STL) for defining template classes that implement associative containers that map keys to values - (STL) for defining several templates that allocate and free storage for various container classes - for declaring several functions that allocate and free storage - (STL) for defining several templates that implement useful numeric functions -

for defining class type_info, the result of the typeid operator - (STL) for defining several templates of general utility - for defining several classes and template classes that support value-oriented arrays - (STL) for defining a template class that implements a vector container 新的C标准库 - for enforcing assertions when functions execute - for classifying characters - for testing error codes reported by library functions - for testing floating-point type properties - for programming in ISO 646 variant character sets - for testing integer type properties - for adapting to different cultural conventions - for computing common mathematical functions - for executing nonlocal goto statements - for controlling various exceptional conditions - for accessing a varying number of arguments - for defining several useful types and macros - for performing input and output - for performing a variety of operations - for manipulating several kinds of strings - for converting between various time and date formats - for manipulating wide streams and several kinds of strings - for classifying wide characters 旧的C标准库 - for enforcing assertions when functions execute - for classifying characters - for testing error codes reported by library functions - for testing floating-point type properties -

for defining several iostreams template classes that manipulate exteral files - for declaring several iostreams manipulators that take an argument - for declaring the iostreams objects that manipulate the standard streams - for declaring several functions that allocate and free storage - for declaring several template classes that aid migration from older versions of the Standard Template Library
