• First Stage: Put in steps of algorithm as comments.
  Compile to make sure there's no typos.
  • the code
  • demo (does nothing)
• Second Stage: Declare variables and do the easy steps of getting the input and drawing outer circle.
  Add an extra line to make sure the numbers are being read in correctly (to be removed later).
  Compile and make sure it works before going on.
  • the code
  • demo
• Third Stage: Calculate first angle. Run test cases to make sure calculation is correct.
  Remove the line added to test if numbers were being read in.
  Compile and make sure it works before going on.
  • the code
  • demo
• Fourth Stage: Calculate the rest of the angles, using the positive x-axis as base.
  Compile and make sure it works before going on.
  • the code
  • demo
• Fifth Stage: Add constants for "magic numbers", in this case the radius of 5.
  Compile and make sure it works before going on.
