How to use newline characters in the C programming language?

In the C language, a newline character can be represented using the special escape sequence `\n`. When a program encounters `\n`, it will insert a newline character in the output, causing the text to move to the next line.

Here are some examples:

printf("Hello, World!\n");

In the above code, `\n` is used to insert a newline character at the end of a string, so that the next content in the printout will be on a new line.

printf("Line 1\nLine 2\n");

In the above code, the two ‘\n’ separate the contents of the string into two lines.

You can also use `\n` in a character array to create a string containing multiple lines of text.

char multiLineString[] = "This is line 1.\nThis is line 2.\n";

In the above code, ‘multiLineString’ is an array of characters containing two lines of text, with each line separated by ‘\n’.

In conclusion, by using the escape sequence `\n` in a string, we can represent a new line character in C language and achieve the effect of text wrapping.
