Bitset iterator
WebJan 25, 2024 · I have a bitset which is very large, say, 10 billion bits. What I'd like to do is write this to a file. However using .to_string() actually freezes my computer.. What I'd like to do is iterate over the bits and take 64 bits at a time, turn it into a uint64 and then write it to a file.. However I'm not aware how to access different ranges of the bitset.

Here's an example of how to iterate through a vector using iterators: for (std::vector::iterator it = my_vector.begin(); it != my_vector.end(); ++it) { std::cout<< *it << " "; } Differences. The main difference between list and vector is the way they store …
WebA BitSet object is iterable. The iterator gets all bits up to the most significant bit. If no bits are set, the iteration stops immediately. let bs = BitSet. Random (55); for (let b of bs) {console. log (b);} Note: If the bitset is inverted so that all leading bits are 1, the iterator must be stopped by the user! WebDec 2, 2024 · iterator bitset._Find_next(index) or int bitset._Find_next(index) Parameters: The function accepts one mandatory parameter index which specifies the index after which the first set bit is to be found in the bitset.

WebWhat should std::bitset::iterator::operator*() return? A naïve choice would be the numeric index of the bit position represented. In practice, the most useful result is another bitset value b such that b.count() == 1, usable as a bitmask to apply against other instances. In this view, a bitset is a
