C++: Proper way to iterate over STL containers

Question

In my game engine project, I make extensive use of the STL, mostly of the std::string and std::vector classes.

In many cases, I have to ite

Answer 1

Native for-loop (especially index-based) - it's C-way, not C++-way.

Use BOOST_FOREACH for loops.

Compare, for container of integers:

typedef theContainer::const_iterator It;
for( It it = theContainer.begin(); it != theContainer.end(); ++it ) {
    std::cout << *it << std::endl;
}

and

BOOST_FOREACH ( int i, theContainer ) {
    std::cout << i << std::endl;
}

But this is not perfect way. If you can do your work without loop - you MUST do it without loop. For example, with algorithms and Boost.Phoenix:

boost::range::for_each( theContainer, std::cout << arg1 << std::endl );

I understand that these solutions bring additional dependencies in your code, but Boost is 'must-have' for modern C++.
