Advantages of std::for_each over for loop

Question

Are there any advantages of std::for_each over for loop? To me, std::for_each only seems to hinder the readability of code. Why do then some coding

Answer 1

Personally, any time I'd need to go out of my way to use std::for_each (write special-purpose functors / complicated boost::lambdas), I find BOOST_FOREACH and C++0x's range-based for clearer:

BOOST_FOREACH(Monster* m, monsters) {
     if (m->has_plan()) 
         m->act();
}

vs

std::for_each(monsters.begin(), monsters.end(), 
  if_then(bind(&Monster::has_plan, _1), 
    bind(&Monster::act, _1)));
