Concepts in Programming Languages

Lecturer: Dr M.P. Fiore

No. of lectures: 8

Aims

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.

Lectures

Introduction, motivation, and overview. What is a programming language? Application domains in language design. Program execution models. Theoretical foundations. Language standardization. History.
The first procedural language: FORTRAN (1954-58). Execution model. Data types. Control structures. Storage. Subroutines and functions. Parameter passing.
The first declarative language: LISP (1958-62). Expressions, statements, and declarations. S-expressions and lists. Recursion. Static and dynamic scope. Abstract machine. Garbage collection. Programs as data. Parameter passing. Strict and lazy evaluation.
Block-structured procedural languages: Algol (1958-68), BCPL (1967), Pascal (1970), C (1971-78). Block structure. Parameters and parameter passing. Stack and heap storage. Data types. Arrays and pointers.
Object-oriented languages -- Concepts and origins: Simula (1964-67), Smalltalk (1971-80). Dynamic lookup. Abstraction. Subtyping. Inheritance. Object models.
Types, data abstraction, and modularity: C++ (1983-98), SML (1984-97). Types in programming. Type systems. Type checking and type inference. Polymorphism. Overloading. Type equivalence. Information hiding. Modularity. SML module system: signatures, structures, and functors. [2 lectures]
State of the art.

Objectives

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
