Task 5

Start
Input initial cost (C)
If (C) is greater than 100:
  Rate (R) = 15%
Else:
  Rate (R) = 10%

Task 6

Logic error
- Definition: The logic with which the program is built is flawed, thus causing
  it to behave in unexpected ways. It is much harder to detect, because the
  machine executes the code correctly, yet the outcome is undesired.
- Example: You write a program that is supposed to exit out of a loop when an
  index 'i' goes beyond 10. In the condition section where the loop is declared
  you write 'i < 10', so the program exits when 'i' is no longer lesser than 10,
  exitting at 9 instead of 10.
- Ways to avoid or deal with this kind of error: Do constant tests to verify the
  results are the ones expected. Consider edge cases, where very strange
  conditions are met, to truly test the consistency of your code's output.
