[edit] Example
Run this code
#include <iostream> #include <iterator> #include <ranges> #include <sstream> int main() { auto letters = std::istringstream {"ABCDEFGHIJK"}; auto chunks = std::ranges::istream_view <char>(letters) | std::views::chunk (4); for (auto chunk : chunks) { // chunk is an object of type chunk_view::outer_iterator::value_type std::cout << '['; for (auto inner_iter = chunk.begin(); inner_iter != std::default_sentinel ; ++inner_iter) std::cout << *inner_iter; std::cout << "] "; } std::cout << '\n'; }
Output:
[ABCD] [EFGH] [IJK]
