We can either use iterators, which requires a considerable amount of boiler-plate, or we can use the std::for_each() algorithm and move our loop body into a predicate, which requires no less boiler-plate and forces us to move our logic far from where it will be used. In contrast, some other languages, like Perl, provide a dedicated \"foreach\" construct that automates this process. BOOST_FOREACH is just such a construct for C++. It iterates over sequences for us, freeing us from having to deal directly with iterators or write predicates.", 8 "category": [ 9 "Algorithms", 10 "Emulation" 11 ], 12 "maintainers": [ 13 "Eric Niebler <eric -at- boostpro.com>" 14 ] 15} 16
