The ASCII table defines 128 characters: 33 control characters (0–31 and 127), the space character (32), and 95 printable characters (33–126). Every programmer should know a few key values by heart: 'A' is 65, 'a' is 97 (32 apart — the same as the space character, making case conversion a simple bit flip), '0' is 48, and newline (LF) is 10. Click any row in the table to look up its full details above.
