What does lf mean in C language?

\lf

\lf in C language represents the newline character (Line Feed) in C language. It is an escape sequence that represents a character with ASCII code value 10.

The newline character moves the cursor to the beginning of the next line and is typically used to create a new line in text output. Similar escape sequences are:

  • \r: carriage return character, moves the cursor to the beginning of the current line.
  • \n: Newline character, moves the cursor to the beginning of the next line.

In Windows operating systems, line breaks are usually represented by "\r\n", which is a combination of carriage return and line feed characters. In Unix and Linux systems, only "\n" is used to represent a newline.

The following is an example showing how to use \lf to create a new line:

<code class="c">#include <stdio.h>

int main() {
    printf("This is line 1.\n");
    printf("This is line 2.");
    return 0;
}</code>
Copy after login

Executing this program will output:

<code>This is line 1.
This is line 2.</code>
Copy after login

where, the "\n" escape sequence Causes "This is line 1." and "This is line 2." to be output to different lines.
