Configuring Your Voice Settings. Before you're able to use Steam Voice Chat you'll need to configure your microphone within your Steam settings. This can be done from the Steam client by clicking on the button labelled Steam and then choosing Settings from the drop down menu.
You declare that a class is the subclass of another class within The Class Declaration. For example, suppose that you wanted to create a subclass named SubClass of another class named SuperClass.

If a superclass instance is assigned its value from a subclass instance, member variables defined in the subclass cannot be copied, since the superclass has no place to store them.
