Concepts in Programming Languages
No. of lectures: 8
Suggested hours of supervisions: 2
Prerequisite courses: None.
The general aim of this course is to provide an overview of the basic concepts that appear in modern programming languages, the principles that underlie the design of programming languages, and their interaction.
- Introduction, motivation, and overview. What is a programming language? Application domains in language design. Program execution models. Theoretical foundations. Language standardization. History.
- The ancestors: Fortran, Lisp, Algol and Pascal. Key ideas: procedural (Fortran), declarative (Lisp), block structured (Algol and Pascal). Execution models (abstract machines), data types, control structures, storage, arrays and pointers, procedures and parameter passing, scope, strict and lazy evaluation, garbage collection. Programs as data (Lisp).
- Object-oriented languages -- Concepts and origins: Simula (1964-67) and Smalltalk (1971-80). Dynamic lookup. Abstraction. Subtyping. Inheritance. Object models.
- Languages for parallel processing. Shared-memory concurrency with spawn/sync (OpenMP, Cilk, X10). Distributed-memory models (the actor model, Erlang).
- Types. Types in programming languages. Type systems. Type safety. Type checking and type inference. Polymorphism. Overloading. Type equivalence.
- Data abstraction and modularity: SML Modules (1984-97). Information hiding. Modularity. Signatures, structures, and functors. Sharing.
- Scala: a principled feature-rich language. Procedural and declarative aspects. Blocks and functions. Classes and objects. Generic types and methods. Variance annotations. Mixin-class composition.
- More-advanced concepts and idioms. Haskell monads, type classes. Continuation passing style and call/cc. Dependent types.
At the end of the course students should
- be familiar with several language paradigms and how they relate to different application domains;
- understand the design space of programming languages, including concepts and constructs from past languages as well as those that may be used in the future;
- develop a critical understanding of the programming languages that we use by being able to identify and compare the same concept as it appears in different languages.
