Study Notes
Programming Overview
- Programming involves creating instructions for computers using a programming language.
- Key steps in programming include understanding the problem, writing code, testing and debugging, optimizing, and maintaining.
Key Steps in Programming
- Understanding the Problem: Break down complex tasks into smaller, manageable components.
- Writing Code: Utilize programming languages like Python, Java, and C++ to compose instructions for execution.
- Testing and Debugging: Execute code to ensure proper functionality; identify and resolve any errors.
- Optimizing: Enhance code efficiency and performance for better execution.
- Maintaining: Continuously update and refine code based on changing requirements or newly discovered issues.
Notable Programming Languages
- JavaScript: Created by Brendan Eich; widely used for web development.
- Java: Developed by James Gosling; known for its platform independence.
- Python: Designed by Guido Van Rossum; praised for its readability and simplicity.
- Ruby: Invented by Yukihiro Matsumoto; recognized for its elegant syntax.
- PHP: Developed by Rasmus Lerdorf; commonly used for server-side web development.
- C++: Created by Bjarne Stroustrup; offers low-level memory manipulation capabilities.
- C#: Developed by Anders Hejlsberg; primarily used for Windows applications.
- Go: Designed by Robert Griesemer; known for its concurrency features and simplicity.
Object-Oriented Programming (OOP) Principles
- Encapsulation: Bundling data with methods that operate on that data, restricting direct access.
- Inheritance: Creating new classes based on existing ones, promoting code reuse and hierarchical relationships.
- Polymorphism: Allowing objects to be treated as instances of their parent class, enabling method overriding.
- Interfaces: Defining contracts that classes can implement, ensuring that certain methods are available in different class types.
