This reference guide is an alphabetical listing of the C++ classes in the Standard C++ Library. The entry for each class includes:
Either a general category to which the class belongs or an illustration showing the inheritance hierarchy
A brief summary of the class functionality
A synopsis indicating the header file(s) associated with the class
A description of the class
The C++ code that describes the class interface
All methods associated with the class, including constructors, operators, member functions, etc.
The constructors, operators, member functions, etc. are grouped together and listed alphabetically within each group. These groups are not a part of the C++ language, but they are a useful way to organize information.
Examples and warnings
Entries that are not classes include different information. In general, there is still a brief summary of the entry's function, followed by a more detailed description, and in many cases an example.
