#includeIn this example, we create a new knob object called "volumeKnob", with a minimum value of 0, maximum of 100, and a starting value of 50. We then set the value of the knob to 75, and retrieve the current value of the knob using "getValue()". The CPP KNOB Value library is likely available as a package or library through a number of different sources, such as GitHub, Bitbucket, or other similar repositories.Knob volumeKnob(0,100,50); volumeKnob.setValue(75); int value = volumeKnob.getValue();
