The aim of the course is to present the structural, operational approach to programming language semantics. A number of paradigmatic untyped and typed languages will be introduced. The entire course will focus on the concepts of operational semantics and type system. Formal techniques for verifying the behaviour of programs will be introduced.
(i) Mathematical induction over the natural numbers;
(ii) Structural induction;
(iii) Rule induction.
Big step and small step semantics for simple languages including
(i) Exp, Bool, languages for arithmetic and Boolean expressions
(ii) the imperative language of while commands While
(iii)the functional languages and simple variations on them; call-by-name and call-by-value semantics
(iv) Some easy object oriented languages.
(i) Typing assignments for the functional languages Fun and Lambda
(ii) Progress and preservation.
(iii) For Lambda you should be familiar with the computational consequences of using types; in particular the need for explicit fixpoint operators.
The examination consists of a written and oral test.
