CR and LF arecontrol characters orbytecode that can be used to mark a line break in a text file.

• CR =Carriage Return (\r,0x0D in hexadecimal, 13 in decimal) — moves the cursor to the beginning of the line without advancing to the next line.
• LF =Line Feed (\n,0x0A in hexadecimal, 10 in decimal) — moves the cursor down to the next line without returning to the beginning of the line.

A CR immediately followed by a LF (CRLF,\r\n, or0x0D0A) moves the cursor to the beginning of the line and then down to the next line.
