    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).
    • 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.
