1. Define what counts as a word
A word is typically a sequence of non-whitespace characters. However, hyphenated words, contractions (don't), and numbers can be counted differently. Define your rules before counting. Most tools split on whitespace by default.
输入Hello world don't输出3 words (default) or 4 (split on apostrophes) -
2. Count the metrics
Count characters (with or without spaces), words, lines (split on newlines), and sentences (split on .!?). Each metric has different rules. Character count may include or exclude whitespace; line count may include or exclude empty lines.
输入Hello world\nSecond line输出chars: 18 | words: 4 | lines: 2 -
3. Report and use the statistics
Display the counts clearly. For writing, word count is most common. For code, line count is common. For tweets or SMS, character count matters. Use the appropriate metric for your context.
