\b The ASCII standard (American Standard Code for Information Interchange) was derived from earlier telegraph and teletype codes. Backspace (8) meant literally move the printing head one character backward — often used to overtype or delete.

Fun fact: Backspace is the same as the Delete key (ASCII 127 in some systems). Backspace moves the cursor backward; Delete removes the character under the cursor. Quick reference table | Control Character | ASCII Decimal | Escape Sequence | |------------------|---------------|------------------| | Backspace (BS) | 8 | \b | | Tab | 9 | \t | | Line Feed | 10 | \n | | Carriage Return | 13 | \r | | Delete (DEL) | 127 | (none standard) | Example in Python # Print "Hello" then backspace then "Hi" print("Hello\b Hi") # Might output "Hell Hi" depending on terminal Note: Modern terminals and text systems may handle Backspace differently — but the ASCII value 8 remains universally recognized. Need other ASCII values? Just ask!

If you’ve ever worked with low-level programming, terminal input, or data streams, you might have needed the ASCII value for the Backspace key .
