C string new line

A classic!

In C, a newline character is represented by the character \n. This is a special character that tells the terminal or console to move to the next line.

Here are a few ways to include a newline character in a C string:

1. Using the \n escape sequence:

   char str[] = "Hello\nWorld!";

   This will create a string with the text "Hello" followed by a newline character, and then the text "World!".

2. Using the printf function:

   printf("Hello\nWorld!\n");

   This will print the string "Hello", followed by a newline character, followed by the string "World!", and finally another newline character.

3. Using the puts function:

   puts("Hello\nWorld!");

   This will print the string "Hello\nWorld!" followed by a newline character.

4. Using the sprintf function:

   char str[20];
   sprintf(str, "Hello\nWorld!");

   This will create a string buffer str and fill it with the text "Hello\nWorld!".

Note that in all cases, the \n character is a single character, not a string. It's a special character that tells the terminal or console to move to the next line.
