What does it mean when we say a programmer using a function should be able to treat the function like a black box?
a. This is meaningless. One must know how a function does its job to effectively use it. b. One must be able to rely on the description of the preconditions (requirements for use of the function) and the postconditions (promise of behavior to use the function). c. If one codes an application that uses a function with a knowledge of the internal mechanism of that function, then when the function’s maintainer changes its internal mechanism, the application programmer could be faced with changing the application code extensively. d. The most efficient programs are the ones that each function is designed to maximally use the internal behavior of every other function to speed up the code.
