Suppose we want to analyze the user interaction aspect for an alarm clock design task. The clock shows the time of day. Using buttons, the user can set the hours and minutes fields individually, and choose between 12 and 24-hour display. It is possible to set one or two alarms. When an alarm fires, it will sound some noise. The user can turn it off, or choose to 'snooze'. If the user does not respond at all, the alarm will turn off itself after 2 minutes. 'Snoozing' means to turn off the sound, but the alarm will fire again after some minutes of delay. This 'snoozing time' is pre-adjustable. (1) Identify the top-level functional requirement for the clock, and model it with a use case diagram. Please develop this use case analysis using VP-UML software tool. (2) Assume that 'snooze' would be one of your use cases. Work it out to the fully dressed level. Please develop this use case analysis using VP-UML software tool.
