The template class describes an object that controls a varying-length sequence of elements of type T. The sequence is stored as an array of T. It differs from template class vector in two important ways:

  • It defines numerous arithmetic operations between corresponding elements of valarray<T> objects of the same type and length, such as x = cos(y) + sin(z).
  • It defines a variety of interesting ways to subscript a valarray<T> object, by overloading operator[].
