Detailed Description

   template<class _Tp>
       class std::valarray< _Tp >" Smart array designed to support numeric processing.

       A valarray is an array that provides constraints intended to allow for effective
       optimization of numeric array processing by reducing the aliasing that can result from
       pointer representations. It represents a one-dimensional array from which different
       multidimensional subsets can be accessed and modified.

       Template Parameters:
           _Tp Type of object in the array.
