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.
