A string of characters

In the case of Listing 3, you can think of the characters between the quotation marks as characters that will be displayed on the screen (with one exception).

The newline character sequence

The exception is that the two-character sequence \n is not displayed as characters.

Rather, in combination, these two characters cause the screen cursor to go to the beginning of a new line on the screen.

This two-character sequence is often referred to as the newline escape character.
