Iterating over set bits quickly – Daniel Lemire

WebDec 27, 2016 · The underlying issue is that std::bitset doesn't have iterators, so the familiar STL algorithm functions such as std::copy, std::copy_n, std::transform, etc. that require iterators are difficult, if not impossible to be used if std::bitset is a source (or target) in the algorithm function. WebI have a custom bitset class implementation in C++. I often iterate over the indexes of bits that are set in the bitset (i.e. for bitset '10011' I want to iterate over numbers 0, 3, 4.)
