    Study Notes

    Chapter 1 - History of Programming

    • Programming has developed gradually over centuries, rooted in tools like the abacus and the development of the numbering system.
    • Early programs were used for machinery like looms and calculating machines during the Industrial Revolution.
    • Programming languages evolved to increase sophistication and ease of use, allowing better human-computer communication.

    What is a Programming Language?

    • Programming languages are tools to help programmers.
    • They allow writing instructions for machines understandable to both humans and machines.
    • A programming language translates human-readable code into machine-readable code (binary).
    • Programming languages provide a standard way to express algorithms to solve problems.

    Language Models

    • Imperative languages use explicit sequences of steps to produce results (e.g. C, Pascal, Fortran).
    • Functional languages use lambda calculus and function applications (e.g. Lisp, Scheme).
    • Logic programming builds from statements in predicate logic (e.g. Prolog).
    • Object-oriented programming uses interacting objects with state and behaviours (e.g. Simula, Smalltalk-80, Java).
    • Scripting languages support diverse applications, interpreted, or combined (e.g. JavaScript, VBScript).
    • Parallel languages involve communicating processes (e.g. C*),

    Evaluating Languages

    • Understandability and readability for human users.
    • Cost of development and maintenance.
    • Robustness and reliability, error avoidance.
    • Appropriateness for type of problem and tasks to be solved.
    • Flexibility to change and update programs.
    • Quality-based evaluation, if applicable.
