Synopsis

#include <algorithm>

template <class InputIterator, class Function>

void for_each(InputIterator first, InputIterator last,

Function f);

Description

The for_each algorithm applies function f to all members of the sequence in the range [first,

last), where first and last are iterators that define the sequence. Since this a non-mutating

algorithm, the function f cannot make any modifications to the sequence, but it can achieve

results through side effects (such as copying or printing). If f returns a result, the result is

ignored.
