CSE3302 Programming Languages (things to say)

• Dr. Carter Tiernan

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.

Analysis of Paradigms

• Name structures
• Data structures
• Control structures

Paradigms

• Procedural
• Object-oriented
• Functional
• Logic
• What differentiates these paradigms?

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

Issues with Paradigms

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

Other Paradigms (?)

Paradigm questions

• Why have different language paradigms developed?
• Which comes first - a new language or a new paradigm?
• How does a paradigm help us?

CSE3302 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 MacLennan does? Should we teach both? Using the language structure?

CSE3302 Questions

• “concepts” approach versus the “comparison” approach (MacLennan)
• Would you prefer the concepts approach?
• Would it be easier or harder to compare languages?
• Topics that could be added to CSE3302?
