Study Notes

Programming Concepts

  • Computer programming involves designing and building applications in a logical manner.
  • Key areas influenced by programming include automation, software applications (for computers and mobiles), operating systems, and games.

Programming Language

  • A formal language that directs instructions to a computer.
  • Examples of programming languages include Ruby, C++, C#, Java, Kotlin, MySQL, Python, and JavaScript.

Programmers

  • Individuals who write program codes categorized into:
    • System Programmers
    • Application Programmers
    • Types of Application Programmers: Database app developers, web app developers, game developers, and micro device programmers.

Importance of Programming

  • Currently among the most in-demand jobs.
  • Provides genuine happiness through creating beneficial solutions for others.
  • Offers lucrative salary prospects.

Software vs. Hardware

  • Software consists of coded instructions for computer operations.
  • Hardware refers to the physical components of a computer, including input and output devices.

Elements of Programming

  • Input: Data entered by the user through devices like keyboards or mice.
  • Data: Storage for the input collected.
  • Operation: Utilizes mathematical, relational, and logical operators to process data.
  • Output: Data extracted and displayed after processing.
  • Conditional Execution: Manages data manipulation based on specific conditions.
  • Loops: Repeat instruction sets until a condition is met.
  • Subroutines: Break large programs into reusable smaller programs.

Problem Solving in Programming

  • A step-by-step approach to create effective products through planning, analysis, design, development, testing, and debugging.

Pseudocode

  • A method for representing an algorithm in a simplified way resembling programming syntax, making it comprehensible for individuals with minimal programming knowledge.
  • Often referred to as false codes, useful for algorithm representation.

Pseudocode Naming Conventions

  • Let / Initialize: For variable initialization.
  • Input: Indicates the variable to be used in the process.
  • Output / Print: Represents a value to be displayed.
  • IF / ELSE: Represents conditional statements used in programming logic.
