    Study Notes

    Course Overview

    • Course Title: Programming 1
    • Description: Introduces fundamental concepts in computer programming and applied techniques.
    • Prerequisite: None required.
    • Contact Hours: 2 hours of lecture and 3 hours of lab weekly.
    • Credit: 3 units awarded.

    Course Content

    • Programming Definition: An organized list of instructions that directs a computer's behavior, similar to a recipe.
    • Purpose of Programs: Simplifies tasks, ensures accurate results, and facilitates daily activities.
    • Types of Programming Languages: Differentiated into web languages, software languages, and multiple generations of languages.
    • Compilers vs. Interpreters: Compilers convert high-level languages to low-level languages for the CPU, while interpreters translate them without compiling.

    Programming Languages

    • Web Languages: Include HTML, XML, JavaScript, PHP, among others.
    • Software Languages: Examples are C, C++, Visual Basic, and Java.
    • Generations of Languages:
      • 1GL: Primitive languages using binary code.
      • 2GL: Assembly languages utilizing symbolic names.
      • 3GL: High-level languages like C and Java, use plain syntax.
      • 4GL: Closer to human language, often for database access (e.g., SQL).
      • 5GL: Used for artificial intelligence and neural networks.

    Designing and Creating Programs

    • Algorithm: A clear set of steps for solving problems, analogous to a recipe.
    • Flowcharts: Visual representation of processes using symbols and arrows to indicate flow.
    • Basic Symbols in Flowcharts: Different shapes represent different types of instructions or processes.
    • Relational and Arithmetic Operators: Used in programming for comparisons and mathematical calculations, with defined precedence rules.

    Course Requirements

    • Completion includes quizzes, lab exercises, seatwork, a project, midterm, and final examinations.
    • Practical project involves creating a simple system using Java.

    Sample Problems

    • Algorithms and flowcharts to solve common tasks, such as:
      • Age verification for web access.
      • Calculating average grades.
      • Determining commission rates based on sales.
    • Implementation of flowcharts to demonstrate logical flow in problem-solving.

    Key Programming Concepts

    • High-Level Language: Requires a compiler or interpreter; easier for humans to understand.
    • Low-Level Language: Executes directly on the CPU, more complex for human understanding.
    • Mathematical Operations: Follow specific order of operations, crucial for accurate computations.

    Additional Notes

    • A program's essential components include variables (data storage) and statements (instructions).
    • Understanding both low-level and high-level languages is crucial for a comprehensive grasp of programming fundamentals.
    • Mastery of algorithms is essential to developing efficient and effective computer programs.
