< p > An < a class = "reference internal" href = "./integral-sequence-wrapper.html" > Integral Sequence Wrapper</ a > is a class template that provides a concise
interface for creating a corresponding sequence of < a class = "reference internal" href = "./integral-constant.html" > Integral Constant</ a > s. In
particular, assuming that < tt class = "literal" >< span class = "pre" > seq</ span ></ tt > is a name of the wrapper's underlying
sequence and < em > c</ em >< sub > 1</ sub > ,< em > c</ em >< sub > 2</ sub > ,... < em > c</ em >< sub > n</ sub > are integral constants of an integral type < tt class = "literal" >< span class = "pre" > T</ span ></ tt > to
be stored in the sequence, the wrapper provides us with the following
