Study Notes
Unit Overview
- Focus on the development of programming languages and paradigms.
- Assess considerations for selecting a programming language.
- Evaluate programming principles relevant to language design.
- Analyze compiler design tools, specifically Lex and Yacc for building a primitive compiler.
Teaching Structure
- Combination of 2-hour lectures and 1-hour tutorials.
- Tutorials may require additional time for completion.
- Assessment methods include in-class tests, assignments, and final assessments.
Lecture Approach
- Notes serve as a broad structure for the instructor, providing context for demonstrations.
- Emphasis on active participation in lectures over passive note reading.
Programming Paradigms
-
Imperative Paradigm:
- Explicit, algorithmic steps defining how tasks are accomplished.
- Characteristics include variable manipulation and states.
-
Declarative Paradigm:
- Specifies desired outcomes rather than processes.
- Focus areas include Logic and Functional programming.
Imperative Paradigms Examples
- Procedural: Fortran, ALGOL, C.
- Object-Oriented: Java, C#, Kotlin.
- Example: Variable manipulation with
x = 0; x = x + 1;.
Declarative Paradigms Examples
-
Logic Programming: Primarily using Prolog.
- Involves facts and rules, e.g.,
food(pizza).
- Involves facts and rules, e.g.,
-
Functional Programming:
- Emphasizes mathematical function mimicry.
- Avoids variable use and side effects through recursion, e.g., Fibonacci function.
Paradigm Characteristics
- Paradigms are flexible; many languages are multi-paradigm.
- Languages can be used in various styles, e.g., JavaScript's versatility.
Programming Principles
- Objective: Discuss the question of the "best" programming language.
- Importance of context: No definitive answer exists.
- Properties to consider:
- Readability: Understandability of the program.
- Writability: Capability to solve problems effectively.
- Reliability: Consistency of program function under varied conditions.
Language Characteristics
- Simplicity: Clear and straightforward constructs.
- Orthogonality: Well-defined rules with minimal exceptions.
- Data Types: Support for different data structures.
- Syntax Design: Clarity and ease of use in language syntax.
- Support for Abstraction: Ability to abstract complex data structures.
- Expressivity: Capability of the language to concisely represent ideas.
- Type Checking: Mechanisms for validating variable types.
- Exception Handling: Framework for managing errors.
- Restricted Aliasing: Limitations on interdependencies between entities.
Understanding Properties and Characteristics
- Use properties and characteristics to evaluate and discuss programming languages critically.
- Enrich personal perspectives on different programming languages.
Summary Points
- Emphasis on understanding three properties and nine characteristics of programming languages.
- Exposure to various programming paradigms and an array of languages.
- Encouragement to engage with and analyze programming languages through hands-on experience.
Reading Assignments
- Chapter 1 sections cover:
- Reasons for studying programming languages.
- Programming domains and applications.
- Criteria for language evaluation.
- Trade-offs in language design.
