What is: Abstract base class, and Pure Virtual function - C++

  • In the cases where the derived classes may share the common functionality
    but with altogether "different" definitions, it makes sense to force the
    developers to create their own definitions for those common functions in
    concerned derived classes.
    This can be achieved by making the class "abstract".
  • A class is called an "abstract" class when it contains at least one "pure

removing extra console terminals

Many Linux distros are installed to have multiple consoles, selected using ctrl-alt-f1 through to ctrl-alt-f6. Where memory is extremely tight, this can be reduced to save some space, by commenting out the relevant [i/]/sbin/getty[/i] lines in /etc/inittab. This will also mean that X will be invoked from a different ctrl-alt-f sequence.

Note that this will only save around half a meg of resident memory per console, so for conventional desktop/laptop systems it is not worth changing....
