C++ Library -

Introduction

It contains utilities in unrelated domains.

• Pairs − these objects can hold two values of different types: pair, make_pair, piecewise_construct, piecewise_construct_t.
  
• Generic relational operators − It is a standard definitions for the relational operators !=, >, <= and >= under a specific namespace: rel_ops.
• Rvalue casts (C++11) − It allows the generation of rvalue references: forward, move, move_if_noexcept, declval.
• Generic swap function − This a standard definition used by default by the components of the standard library for all types that do not provide their own overload: swap.
