Punctuation
Punctuation in character encoding
ASCII includes 32 punctuation and symbol characters across codes 33-47, 58-64, 91-96, and 123-126. These cover standard marks (period code 46, comma code 44, question mark code 63) plus programming-essential symbols like braces {}, brackets [], and the @ sign.
Many punctuation characters serve double duty in computing. The forward slash (code 47) separates URL paths and filesystem directories. The semicolon (code 59) terminates statements in C, Java, and JavaScript. The hash/pound sign (code 35) starts comments in Python and shell scripts, anchors in URLs, and prefixes hex color codes in CSS. See all of them in the punctuation and symbols group.
