Quiz Stuff

• Use a full sheet of 8½ x 11" paper. (Half sheet? Half credit!)
• Put your last name and first initial in the far upper left hand corner of the paper, where a staple would hit it. (It helps when sorting quizzes!)
  
  Mitchell, W.
  
• No need to write out questions.
• Numbering responses may help you avoid overlooking a question; it's ok to go ahead and pre-number your sheet.
• Two minutes; six questions, plus one extra credit question.
• Can everybody see this line?

Answers

1. What are the three aspects of an expression that we often consider?
   Value, type, and side-effect (reversed vest: t-se-v)
2. What operation in Haskell has higher precedence than any operator?
   function call
3. How would the following type be read aloud? f :: Int -> Bool
   "f has type int to bool"
4. Name one characteristic of the functional paradigm.
   Functions that are like mathematical functions; no side-effects; functions are values; recursion in place of looping.
5. What is an example of (1) a Haskell type (2) a Haskell type class?
   Types: Int, Char, Bool
   Classes: Num, Fractional, Bounded, Eq, Ord
6. Tell me something you learned from the flipped lecture on paradigms.
   A paradigm provides a conceptual framework for understanding and solving problems; a paradigm has a world view, vocabulary, and a set of techniques for solving problems.
