How to use the newline symbol in C language

In C language, there are two commonly used newline symbols ：

• ##'\n'
• "%\n"

' \n'

Function: Inserts a newline character in the string or text output and moves the cursor to the beginning of the next line.

Usage:

<code class="c">printf("Hello\nWorld!");

// 输出：
// Hello
// World!</code>

"%\n"

Function: with '\n ' is the same, but it is an escape character in a formatted string.

Usage:

<code class="c">printf("%%d %%s\n", 10, "Hello");

// 输出：
// 10 Hello</code>

In the format string, "%%\n" will be replaced with a newline character.

Which newline symbol to choose?

In most cases, it is simpler and more convenient to use '\n'. And "%\n" is mainly used when formatting string operations are required.

Other notes:

'\n' is a constant and its value cannot be modified.
• The behavior of newlines may vary between operating systems and compilers.
• On Windows systems, use "\r\n" instead of "\n" for line breaks.
