The meaning of "\n" in C

The "\n" in C is an escape sequence, representing a newline character.

Function:

In a string or character array, "\n" will cause the cursor to move to the next line in the text output. It can be used to create new lines in the output.

Usage:

"\n" can be directly embedded in a string or used as a parameter of the cout statement. For example:

<code class="cpp">// 在字符串中使用 "\n"
std::string text = "Hello\nWorld!";

// 在 cout 语句中使用 "\n"
std::cout << "Hello" << std::endl;</code>

The above code will print the following output:

<code class="text">Hello
World!
Hello</code>

Note:

Different operating systems use different newline conventions. In Windows systems, "\n" means carriage return and line feed (CRLF), while in Linux and macOS systems, "\n" only means line feed (LF).
