Views are a class defined in the std::streambase namespace that allows the user to manipulate data contained in an input stream. Along with the << operator, which is used to read data from the input stream, the reader also has access to the Streambuf class, which allows the reader to manipulate the data contained in the stream and also to read EOF.

Question: how would i use views to get a collection of lines from an input stream (i.e. `cin`), including empty lines? I read a bit on cppreference and it seems that `views::istream<string>(cin)` uses the default `<<` operator, which wouldn't work for what i want

. You could use `views::lines` to create a view of the lines from `std::cin`, like this: ```cpp auto lines = views::lines(std::cin); ``` This view will include empty lines, so you can use it to process your input stream.
