You can't see it, but the bell character (Control G) is embedded in what looks like an empty string on line 10.

The ZX Spectrum had a speaker, rather than a bell. Here we use middle C as a bell tone, but we could produce a different note by changing the final zero to a different value.

Assuming that the platform the program is running on rings the bell when CHR$7 is sent to the VDU driver:

Assuming the output stream is connected to a TTY, printing BEL should ring its bell.

int main() {

printf("\a");

return 0;

 

Inside a function:

System.Console.Write("\a"); // will beep

System.Threading.Thread.Sleep(1000); // will wait for 1 second

// System.Console.Beep() also accepts (int)hertz and (int)duration in milliseconds:

System.Console.Beep(440, 2000); // default "concert pitch" for 2 seconds

On a tty or in <code>-batch</code> mode this emits a BEL character. In a GUI it does whatever suits the window system. Variables <code>visible-bell</code> and <code>ring-bell-function</code> can control the behaviour.

The following will only work in a PostScript interpreter that sends output to a terminal. It will very likely not make a printer beep.

 

=={{header|PowerShell}}==

One can either use the ASCII <code>BEL</code> character which only works in a console (i.e. not in a graphical PowerShell host such as PowerShell ISE):

or use the .NET <code>Console</code> class which works independent of the host application:

There is no standard REXX built-in function to handle the sounding of the bell or a PC's speaker.
