Content of reading exercise #1

  1. Compare and contrast the information contained in precedence and associativity rules with the information contained in order of evaluation rules for expressions.
  2. Compare and contrast iteration and logically controlled loops.
  3. List the control flow mechanisms. Some control flow mechanisms are used predominately in Imperative, Functional, and Logic languages. For each type of language list the control flow mechanisms most commonly associated with that type of language.
  4. What are the differences between a value-model of variables and a reference model of variables?
  5. Why do many languages leave the order of evaluation of the arguments to functions unspecified?
  6. Describe 3 different search strategies that might be used to implement a case statement. Describe the circumstances where each would be desirable.
  7. What is tail recursion? Why is it important?
  8. How does lazy evaluation differ from normal order evaluation?
  9. Why is initialization of variables important? In some languages it is either hard (or expensive) to tell if a variable has been initialized when it is used. Why?
