The code as it is now can connect a camera to a Gunslinger and display a clip according to the state of the Gunslinger object, but it must call showClip() in order to display. Implement an observer pattern implemented using the given Observer class (see Observer.h/Observer.cpp) and Subject classe (see Subject.h/Subject.cpp) such that the camera objects will be automatically notified and updated when the gunslingers’ state is changed without showClip() having to be called by the main function. ///////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////// // // PART 1 [5 marks] // // Make Gunslinger an observable class. // // Alter the GunSlinger class to make it an observable (i.e. subject) class, and include notification of the observer at appropriate // place(s) in the altered GunSlinger class. // ///////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////// ///////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////// // // Part 2 [5 marks] // // Make Camera an observer class. // // The Camera class shows the GunSlinger on the screen according to the value of the state of the Gunslinger (the clip playing // process is here simplified as a textual console output description of the scene).
