    Study Notes

    Computer Programming

    • Computer programming involves designing and building executable programs for specific tasks.
    • Key tasks include analysis, generating algorithms, profiling accuracy and resource consumption, and implementing algorithms.

    Programming Language

    • A formal set of instructions for producing various outputs is defined as a programming language.
    • Programming languages facilitate the creation of programs that execute specific algorithms.

    Source Code

    • Source code is human-readable code usually written in plain text and may contain comments.
    • It is transformed into binary machine code through assemblers or compilers for computer execution.

    Levels of Programming

    • Low-Level Language: Offers no abstraction from hardware, represented in binary (0s and 1s).
    • High-Level Language: Allows programming that is independent of specific computer types.

    Computer Algorithms

    • An algorithm is a self-contained sequence of actions designed to perform tasks like calculations and data processing.
    • Notable historical contributions include:
      • Analytical Engine (Charles Babbage, Ada Lovelace)
      • Plugboard in Type I Tabulator (Herman Hollerith, 1906)
      • ENIAC Coding System (1943)

    Machine Code

    • Assembly Language developed in 1949 constitutes an early programming language.

    History of Computer Programming

    • FORTRAN: Introduced in 1957, the first widely-used high-level language.
    • COBOL: Developed in 1960 for business applications.
    • BASIC: Created in 1964 for beginners by Kemeny, Kurtz, and Keller.
    • PASCAL: Designed by Niklaus Wirth in 1970.
    • C (1972) and C++ (1985) were influential in modern programming.
    • Key languages released in 1995 include Java (James Gosling), JavaScript (Brendan Eich), PHP (Rasmus Lerdorf), and Ruby (Yukihiro Matsumoto).
    • More recent languages include C# (2000), Kotlin (2011), and TypeScript (2012).

    Pseudocode

    • Pseudocode uses short English phrases to outline program tasks clearly.
    • Indentation indicates logical flow, aiding in coding and communication among team members.
    • Early design stages may utilize pseudocode, flow charts, or a combination of both.

    Examples of Pseudocode

    • Sample conditional statements for displaying values based on comparisons.
    • Basic input handling for greeting users based on their name.

    Do’s and Don’ts of Pseudocode

    • Do's:
      • Employ control structures.
      • Use proper naming conventions and limited numbers.
      • Maintain simplicity and conciseness.
    • Don'ts:
      • Avoid abstraction and over-generalization.
