template<class InIt, class OutIt>
OutIt adjacent_difference(InIt first, InIt last,

OutIt adjacent_difference(InIt first, InIt last,
OutIt result, Pred pr);
The first template function stores successive values beginning at result
, for each value of the InIt
iterator I
in the
interval [first, last)
. The first value val
stored (if any) is *I
. Each subsequent value stored is *I - val
, and
val
is replaced by *I
. The function returns result
incremented last - first
times.
The second template function stores successive values beginning at result
, for each value of the InIt
iterator I
in the
interval [first, last)
. The first value val
stored (if any) is *I
. Each subsequent value stored is pr(*I, val)
, and
val
is replaced by *I
. The function returns result
incremented last - first
times.
