Learning outcomes

At the end of the course, the student will know the principal techniques for defining the syntax and the semantics of the most common programming languages; they will also know how to implement the principal constructs.

Course contents

First module, first semester; instructor:

http://www.unibo.it/SitoWebDocente/default.htm?UPN=maurizio.gabbrielli%40unibo.it

The evolution of programming languages. From assembly to higher level languages. Abstract machines, intepreters and compilers. Environment, scoping rules and their implementation. Stack of the activation records; heap. Memory management: garbage collection. Sequence control, procedures, recursion. Types and type checking. Parameters and parameter passing: by value, by reference, by result, by name. Functional parameters; closures. Exceptions. The object-oriented paradigm: classes and objects, initialization, inheritance and late-binding. Subtyping is not inheritance. The logical paradigm. The functional paradigm (Scala). The concurrent paradigm and service-oriented computing (Jolie).

Second module, second semester; instructor:Roberto Gorrieri

http://www.cs.unibo.it/~gorrieri/

Description of a programming language: syntax, semantics, pragmatics and implementation. Syntax (BNF). Structured Operational Semantics (SOS). Regular grammars, regular expressions, and finite automata: equivalences and principal theorems (e.g., pumping lemma). Design of lexical analysers. Lex. Context free grammars and push-down automata: equivalences and principal theorems (e.g., pumping theorem). Deterministic context free grammars: algorithms for parsing; grammars LL(1), LR(0), SLR, LR(1), LALR(1). YACC.
