    Study Notes

    Programming Languages Overview

    • Programming languages facilitate code writing with human-readable syntax.
    • The landscape includes various programming languages and tools tailored for different paradigms and applications.

    Programming Paradigms

    • Definition: Paradigtm refers to structured approaches in code organization and problem-solving.
    • Procedural Programming: Focuses on procedures or functions; emphasizes code reuse and sequential execution.
      • Examples: BASIC, C, C++, Pascal, Java.
    • Object-Oriented Programming (OOP): Centers on objects that encapsulate data and behavior, enhancing modularity and reusability.
      • Examples: Python, VB.NET, C#.
    • Functional Programming: Treats computation as mathematical function evaluation; aims for consistency and minimal side effects.

    Programming Language Classification

    • Low-level Languages: Nearer to machine code; provide direct hardware control. Suitable for tasks needing precision.
      • Examples:
        • Assembly Language: Specific instructions for hardware control.
        • Machine Language: Instructions in binary (0s and 1s).
    • High-level Languages: More accessible for human understanding; abstracts hardware specifics.
      • Examples: C++, Pascal, PHP, Python, Java.
    • Language Selection Factors: Project requirements, performance goals, community support, and availability of libraries/frameworks.

    Key Programming Terminologies

    • Syntax: Set of rules for valid statement formulation in a language.
    • Command: Specific instruction to perform an application task, e.g., “print” for displaying text.
    • Integrated Development Environment (IDE): Software for code formatting, syntax checking, and testing; may support multiple languages or be language-specific.
    • Library: Resource collection of pre-built functions and objects that must be configured for use in an IDE.

    Algorithm Representation Tools

    • Pseudocode: Simplified, readable representation of algorithm steps, usually adhering to common operation symbols and keywords.
      • Key symbols include: Arithmetic (+, -, *, /), Comparison (=, ≠, <, ≤, ≥), Assignment (=), Logical (and, or).
    • Flowchart: Visual representation of algorithm steps, aiding in understanding complex processes.
      • Types:
        • Program Flowcharts: Logical steps in programming tasks.
        • System Flowcharts: Interaction of system components with data flow.
      • Standard symbols include terminal points, input/output operations, processing boxes, decision points, and connectors.

    Rules for Creating Program Flowcharts

    • Use only standard symbols.
    • Maintain top-to-bottom and/or left-to-right flow.
    • Each symbol should have one entry and exit point, except decision symbols.
    • Operations within symbols should be language-independent.
    • Clearly label all decision branches.
