Frequently Asked Questions

What is ASCII?

ASCII (American Standard Code for Information Interchange) is a character encoding standard that assigns numbers 0-127 to letters, digits, and symbols. It is the foundation of most text encoding.

What are control characters?

Control characters (0-31, 127) are non-printable characters used for control purposes like newline (LF, 10), carriage return (CR, 13), tab (TAB, 9), and escape (ESC, 27).

How do I type special ASCII characters?

On Windows, hold Alt and type the decimal code on numpad (e.g., Alt+64 for @). On Mac, use Character Viewer. In code, use escape sequences like \n for newline.
