boost::algorithm::starts_with — 'Starts with' predicate
// In header: <boost/algorithm/string/predicate.hpp> template<typename Range1T, typename Range2T, typename PredicateT> bool starts_with(const Range1T & Input, const Range2T & Test, PredicateT Comp); template<typename Range1T, typename Range2T> bool starts_with(const Range1T & Input, const Range2T & Test);
This predicate holds when the test string is a prefix of the Input. In other words, if the input starts with the test. When the optional predicate is specified, it is used for character-wise comparison.
