ASCII Character: Line Feed

About the Line Feed Character

ASCII code 10 (0x0A) represents the Line Feed (LF) control character. This is a non-printable character defined in the original ASCII standard (1963). It belongs to the format effector group, which controls the layout and positioning of text in output devices like printers and terminals. Control characters occupy codes 0–31 and 127 in the ASCII table and were originally designed for controlling hardware devices, managing communication links, and formatting text output. While many control characters have become obsolete with modern computing, several like LF (Line Feed), CR (Carriage Return), TAB, and ESC remain essential in everyday programming and text processing.
