Line counter
Type something and the most frequent words show up here.
Every line break starts a new line, blank lines included. The paragraph count sits alongside it and ignores blanks, so between the two you can tell how many actual entries you have.
How to count lines
Two conventions collide here and it is worth knowing which you are being asked for. This counts lines the way an editor shows them: text with three line breaks displays as four lines, even if the last is empty. Unix tools like `wc -l` count line *terminators* instead, so the same text gives three — and a file with no trailing newline gives one fewer than the editor shows. Neither is wrong; if a system disagrees with this count by exactly one, a trailing newline is almost certainly why.
Questions
Yes, in the line count. The paragraph count excludes them, so comparing the two tells you how many are blank.
