  • [H2] 1. Consider these functions, expanded from an article by Andrzej Krzemieński: [1] … How many ways could a caller of each function get the arguments wrong, but that would silently compile without error? Name as many different ways as you can.
  • [H2] (a) is_in_values (int val, int min, int max)
  • [H2] (b) is_in_container (int val, int idx_min, int idx_max)
  • [H2] (c) is_in_range (T val, Iter first, Iter last)
  • [H2] 2. Show how can you improve the function declarations in Question 1 by …
  • [H2] (a) just grouping parameters, using a struct with public variables
  • [H2] (b) just using an encapsulated class, using a class with private variables (an abstraction with its own invariant)
  • [H2] (c) just using post-C++20 contract preconditions (not yet valid C++, but something like the syntax in [2])
  • [H2] 3. Consider these three examples, where each shows expressing a boolean condition either as a function precondition or as an encapsulated invariant inside a new type… In each of these cases, which way is better? Explain your answer.
  • [H2] JG Question
  • [H2] Guru Questions
  • [H2] 1. What is a precondition, and how is it related to an assertion?
  • [H2] Explain your answer using the following example, which uses a variation of a proposed post-C++20 syntax for preconditions. [1]
  • [H2] 2. Rewrite the example in Question 1 to show how to approximate the same effect using assertions in today’s C++.
  • [H2] Are there any drawbacks to your solution compared to having language support for preconditions?
  • [H2] 3. If a precondition fails, what does that indicate, and who is responsible for fixing the failure?
  • [H2] Explain how this makes a precondition fundamentally different from every other kind of contract.
  • [H2] 4. Consider this example, expanded from a suggestion by Gábor Horváth:
  • [H2] a) What kinds of preconditions must a caller of calc satisfy that can’t generally be written as testable boolean expressions?
  • [H2] b) What kinds of boolean-testable preconditions are implicit within the explicitly written declaration of calc?
  • [H2] c) Should any of these boolean-testable implicit preconditions also be written explicitly here in this precondition code? Explain.
  • [H2] Our virtual 2021
  • [H2] Today: A few more C++23 features adopted
  • [H2] What’s next
  • [H2] JG Question
  • [H2] Guru Questions
  • [H2] 1. What is a postcondition, and how is it related to an assertion?
  • [H2] Explain your answer using the following example, which uses a variation of a proposed post-C++20 syntax for postconditions. [1]
  • [H2] 2. Rewrite the example in Question 1 to show how to approximate the same effect using assertions in today’s C++. Are there any drawbacks to your solution compared to having language support for postconditions?
  • [H2] 3. Should a postcondition be expected to be true if the function throws an exception back to the caller?
  • [H2] Justify your answer with example(s).
  • [H2] 4. Should postconditions be able to refer to both the initial (on entry) and final (on exit) value of a parameter, if those could be different?
  • [H2] If so, give an example.
  • [H2] JG Question
  • [H2] Guru Questions
  • [H2] 1. Give one example each of an asserted condition whose run-time evaluation is:
  • [H2] a) super cheap
  • [H2] b) arbitrarily expensive
  • [H2] 2. What does the answer to Question 1 imply for assertion checking? Explain.
  • [H2] 3. Give an example of an asserted condition that is in general impossible to evaluate, and so cannot be checked.
  • [H2] Can these kinds of conditions still be useful?
  • [H2] 4. How do these questions help answer:
  • [H2] a) what “levels” of asserted conditions we should be able to express?
  • [H2] b) why the assertions we can “practically” write are a subset of all the ones we might “ideally” like to write?
  • [H2] JG Questions
  • [H2] Guru Questions
  • [H2] 1. What is an assertion, and what is it used for?
  • [H2] 2. C++20 supports two main assertion facilities… For each one, briefly summarize how it works, when it is evaluated, and whether it is possible for the programmer to specify a message to be displayed if the assertion fails.
  • [H2] 3. If an assertion fails, what does that indicate, and who is responsible for fixing the failure?
  • [H2] 4. Are assertions primarily about checking at compile time, at test time, or at run time? Explain.
  • [H2] Posts navigation
  • [H2]
  • [H2]
  • [H3] (a) A vector that is sorted
  • [H3] // (b) A vector that is not empty
  • [H3] (c) A pointer that is not null
  • [H3] (1) Type invariants
  • [H3] (2) Subexpression preconditions
  • [H3] (3) Subexpressions that make the whole precondition false
  • [H3] Putting it all together
  • [H3] Option 1 (basic): Named return object + an exit guard
  • [H3] Option 2 (better): “return post” postcondition pattern
  • [H3] Option 3 (mo’betta): Wrapping up option 2… with a macro
  • [H3] assert
  • [H3] static_assert
  • [H3] Bonus: [[assert: ?
