Namespaces in c++

What is namespace in c++

A namespace is a declarative region that provides a scope to the 
  identifiers (the names of types, functions, variables, etc) inside 
  it. Namespaces are used to organize code into logical groups and to
  prevent name collisions that can occur especially when your code base
  includes multiple libraries
