square_functor
is a function object that computes the square (x*x) of a given element.
T | is a model of Assignable, and if x is an object of type T , then x*c must be defined and must have a return type that is convertible to T . |
square_functor
is a function object. Specifically, it is an Adaptable Unary Function. If f(c)
is an object of class square_functor<T>
, and x
is an object of class T
, then f(x)
returns x*x
