How to find angle between hour and minute hands in an analog clock?

Given a simple clock, we have to find the angle between the hour and minute hands. Since this is a deliberate question, we should obviously be ignoring the thickness of the hands in the clock.


We need to understand the following things before we arrive at our solution.
  • The hour hand moves at the rate of 0.5 degrees per minute.
  • The minute hand moves at the rate of 6 degrees per minute.
The reason for the above statements are obvious if you think a layer deep. Now, for the code (works both for C++ and Java)


Cheers!!
