  1. CS 403 – Programming Languages Class 28 - December 7, 2000 Review & Final words

  2. Final Exam notes • Thursday, Dec 14, 8:00AM • Format: • Fair number of multiple choice questions • Scantron forms! Bring your #2 pencils! • Might be some short discussion (like previous exams)

  3. Final Exam notes • Comprehensive • About 1/3 of exam will cover material in chapters 1-8 (from the first exam). • About 2/3 of exam will cover material in chapters 9-11 & 13-15. • Examination Aid: You may bring one 8 ½ by 11 sheet, handwritten on both sides as an aid to the exam.

  4. Some Example MC Questions • When Ada handles an exception, where does execution continue? (Pick the best option.) • The next line of code after the one that generated the exception. • The next line of code in the procedure that called the exception-causing procedure. • The next line of code after the END of that block. • The program terminates. Execution does not resume.

  5. Some Example MC Questions • Given this code (some call & return), which parameter passing method would give the output: “87 45 15”? • Pass by value • Pass by value-result • Pass by result • Pass by name • None of these will give that output.

  6. Some Example MC Questions • Given this code (some call & return) and assuming “pass by value-result”, what would the output be? • 453 27 • 236 -3 • 96 82 • 1024 256 • None of the above

  7. Questions you won’t see! • Which language did we not study in class? • LISP • Scheme • Haskell • Prolog • None of the above

  8. Questions you won’t see! • Which language did we demonstrate at length in class, but you didn’t have to program an assignment in it? • FORTRAN • ML • Haskell • Prolog • None of the above

  9. Questions you won’t see! • …? • LISP • Scheme • Haskell • Prolog • None of the above

  10. Quick Review of Topics • Chapter 1 • Language Evaluation Criteria • Language Design Trade-Offs • Implementation Methods • Chapter 2: Historical Overview • Chapter 3: Syntax & Semantics • Grammars • Parse Trees

  11. Review of Topics • Chapter 4: Names, Bindings, Type Checking and Scopes • Binding & Binding Times • Type checking & Strong Typing • Type compatibility • Scope & Lifetime • Referencing Environments

  12. Chapter 5: Data Types • Primitive data types • Character & String types • User defined types • Array types • Associative types • Record types • Set types • Union types

  13. Chapter 6: Expressions & Assignment Statement • Arithmetic expressions • Overloaded operators • Type conversions • Relational & Boolean expressions • Short circuit evaluation • Assignment Statements • Mixed-mode assignment

  14. Chapter 7: Control Statements • Compound statements • Selection statements • Iteration statements • Unconditional branching • Guarded commands

  15. Chapter 8: Subprograms • Design issues • Local referencing environment • Parameter passing methods • Subprograms as parameters • Overloaded subprograms • Generic subprograms • Separate & Independent compilation • Accessing non-local environments • User-defined overloaded operators

  16. Chapter 9: Implementing Subprograms • General semantics of calls & returns • FORTRAN 77 subprograms • ALGOL-style subprograms (and everything since ALGOL) • Blocks • Implementing Dynamic & Static scoping • Implementing subprogram names as parameters

  17. Chapter 10: ADTs • Abstraction • Encapsulation • Parameterized ADTs • Language examples

  18. Chapter 11: OO Programming • OOP • Design issues for OO languages • Smalltalk • Support for OO in • C++ • Java • Ada

  19. Chapter 12: Concurrency • Skipped! • You’ll see this in CS 426 Operating Systems

  20. Chapter 13: Exception Handling • Basic issues • Exception handling in • PL/I • Ada • C++ • Java

  21. Chapter 14: Functional Programming Languages • Basic ideas… • ML

  22. Chapter 15: Logic Programming Languages • Basic issues • Prolog

  23. Studying for the exam • You may study in groups of 3-5. • You may post up to 5 sample exam questions from each group. • I’ll give one point for each sample question, up to a max of 5, to count as bonus points on the exam. • Post no later that Tuesday 5PM.
