An Overview Of Standard C++Tr1

The document provides an overview of the C++ Technical Report 1 (TR1). TR1 adds new functionality to the C++ standard library in areas such as utility classes like shared_ptr and tuple, containers including hash maps, function objects, type traits, numerics, and regular expressions. It is included in the std::tr1 namespace and provides commonly used components from Boost that fill gaps in the standard library. TR1 helps developers avoid reimplementing commonly needed functionality and provides an expanded toolkit for writing C++ applications.
