Line 3:
In most terminals, if the [[wp:Bell character|Bell character]] (ASCII code 7, <code>\a</code> in C) is printed by the program, it will cause the terminal to ring its bell. This is a function of the terminal, and is independent of the programming language of the program, other than the ability to print a particular character to standard out.
