    Study Notes

    Chapter 1 - History of Programming

    • Programming has developed gradually throughout the centuries
    • Early forms of computation include the abacus and the development of the numbering system
    • The Industrial Revolution saw the development of machinery for calculation
    • Programming languages have evolved over time, reaching current sophistication
    • Various factors in human society enabled programming to develop.

    What is a Programming Language

    • Programming languages are needed for human beings and computers to communicate
    • Computers don't understand everyday language, but understand machine code (1s and 0s)
    • Programming language allows creating algorithms expressed in human-readable form that the computer can translate.

    Language Models

    • Imperative languages use commands for sequenced steps
    • Functional languages based on lambda-calculus, use function definitions and applications
    • Logic languages use statements in a particular logic (e.g., Prolog)
    • Object-oriented languages use objects interacting with each other
    • Declarative languages describe a pattern to match (some functional/logic languages are declarative)
    • Scripting languages support wider application control
    • Parallel languages use multiple processes

    Evaluating Languages

    • Programmers evaluate programming languages based on programmer viewpoint, environment, or organization standards.
    • Readability: Length of names, logical syntax, and use of control structures affect how easy it is to read code.
    • Cost of development and maintenance.
    • Language complexity: The difficulty of syntax can make the software difficult to debug and maintain.
    • Reliability: Robust code that avoids errors.

    Chronology of Programming

    • The abacus was a fundamental early computing tool
    • The development of the numbering system in India and the Arab world were important in early calculation
    • The 18th and 19th centuries saw machinery development for computation (looms, calculating machines).

    The Language Generations

    • First generation: Machine language (numerical instructions)
    • Second generation: Assembly language (symbols to represent instructions).
    • Third generation: Higher level languages easier to use (FORTRAN, COBOL, Pascal, Ada, C, BASIC)
    • Fourth generation: Non-procedural languages (SQL, Postscript, relational databases, orientated languages).
    • Fifth generation: Artificial intelligence/fuzzy logic languages.

    Object-Oriented Concepts

    • Classes and objects.
      • Objects have state (data) and behavior (actions).
      • Classes act as templates for creating objects.
    • Attribute: Characteristic or property of a class
    • Inheritance; Objects can inherit attributes and methods from the class they are a part of.
    • Polymorphism: The ability of a method with the same name to behave differently depending on the object it's operating on.

    11 Encapsulation and Abstraction

    • Encapsulation hides the internal workings of an object from other objects, making objects easier to use without needing to know details
    • Information hiding: Streamlining an object to suit the needs of the software developer.

    12 Messages and Operations

    • Objects communicate with one another by sending messages, each message contains arguments specifying the details.
    • Methods/functions: Actions that objects perform when they receive a message.

    13 Relationships

    • Inheritance: A process where a class (subclass) can inherit properties and behaviors from another related class (superclass).
    • Association: A relationship between objects. This relationship can be one-way or two-way (directional).

    14 Polymorphism

    • Operations can have the same name, but different behavior within different objects.

    Chapter 2 - Variables, Control Structures, and Calculations

    • Variable types

    • Order of precedence in calculations

    • Control structures

      • Sequence structures
      • Selection (if-then-else, case)
      • Loops (repeat-until, while, for)

    Chapter 3 - Data Analysis and Problems

    • Program development process
      • Requirements analysis
      • Design
      • Coding
      • Testing
      • Implementation and support
    • Information organization/structures
    • Diagrams/techniques for program analysis
