6. Portability Concerns

• Please note that the Beep call is not portable and is largely dependent on the OS that we are using.

• The closest "beep" behavior that you can get in standard a C/C++ is to send the '\a' escape sequence to the standard output, that is, either

  • to the stdout stream,

        printf( "\a" );
    

  • or to the std::cout object, for example,

        std::cout << "\a";
    

• The C++ standard inherits this from C standard:

  • "\a (alert) produces an audible or visible alert without changing the active cursor position."

• On most common desktop systems, '\a' produces a beep from the system speaker, assuming the computer has one.
