CSE 3302 Programming Languages (things to say) Dr. Carter Tiernan Programming Languages Misc. 1 jcmt

Programming Language Paradigms • A programming paradigm is a paradigmatic style of programming (compare with a methodology which is a paradigmatic style of doing software engineering). • A programming paradigm provides (and determines) the view that the programmer has of the execution of the program. • The relationship between programming paradigms and programming languages can be complex since a programming language can support multiple paradigms. Programming Languages Misc. 2 jcmt

Analysis of Paradigms • Name structures • Data structures • Control structures Programming Languages Misc. 3 jcmt

Paradigms • • Procedural Object-oriented Functional Logic What differentiates these paradigms? Programming Languages Misc. 4 jcmt

Paradigm Definitions Focusing on • actions in a program with control handled through subprograms • elements of a system to be modeled and the behaviors of those elements • application of functions with little distinction between program and data • defining the program logic and not explicitly handling program control Programming Languages Misc. 5 jcmt

Issues with Paradigms • One language = one paradigm? • “Programming” vs. “Computer” language? • Languages that don’t ‘fit’ in the four paradigms discussed Programming Languages Misc. 6 jcmt

Other Paradigms (? ) Programming Languages Misc. 7 jcmt

Paradigm questions • Why have different language paradigms developed? • Which comes first - a new language or a new paradigm? • How does a paradigm help us? Programming Languages Misc. 8 jcmt

CSE 3302 Questions • Why do we have you study languages? (Have you learned anything that might be useful? ) • Should we make a distinction between “programming” and “computer”languages as Mac. Lennan does? Should we teach both? Using the language structure? Programming Languages Misc. 9 jcmt

CSE 3302 Questions • “concepts” approach versus the “comparison” approach (Mac. Lennan) – Would you prefer the concepts approach? – Would it be easier or harder to compare languages? • Topics that could be added to CSE 3302? Programming Languages Misc. 10 jcmt
