Language support

Basic types and their properties

See this for additional information about fundamental types implicitly defined by the language

Various headers define some basic types that are used throughout the library.

To enhance portability, several fixed width integer types are defined Template:mark c++0x feature

The numeric_limits class template provides an interface to query properties of all fundamental types.

Lot of macros define properties of the fundamental types this is deprecated in favour of numeric_limits interface

Dynamic memory allocation

Several memory utilities provide both low and high level support for managing memory dynamically.

Error handling

Several error handling utilities provide both low and high level error handling primitives.

Runtime type identification

Language builtin typeid operator allows to query object type on either on runtime or compile-time depending on the information available to the compiler. Several support classes are defined, which provide convenient interface with the feature.

Initializer lists

Class template initializer_list allows to use initializer list syntax to initialize non Plain-old-data types Template:mark c++0x

General utilities

Program utilities

Several program utilities are defined, which implement program termination and communication with the environment primitives, as well as signal handling and non-local jumps.

Compile time rational arithmetic

Several classes and functions provide compile time rational arithmetic support. Template:mark c++0x

Date and time

Several classes and functions provide minimal time and date support.

Bitset

Class bitset implements constant length bit array

Function objects

Several useful function objects performing simple operations are provided

Type traits

Several specially crafted class templates implement compile-time interface to query and set various properties of types.

Pairs and tuples

Class template tuple implements fixed size container, which holds elements of possibly different types Template:mark c++0x

Class template pair implements binary tuple, i.e. a pair of values.

Swap, forward and move
