An introduction to programming languages paradigms, including functional and logic programming, and the suitability of various languages for particular programming tasks. Students write sample programs in the studied languages. The languages are used to illustrate programming language constructs such as scoping and binding, type systems, storage management and operating environments. This illustration is accompanied by an introduction to the implementation of programming languages, such as parsing, semantic analysis, symbol tables, memory allocation and code generation. Students complete a series of assignments to implement a language chosen by the instructor.
