Study Notes

Fundamental Concepts

Computer programming is the process of designing, writing, testing, debugging, and maintaining the source code of computer programs.
Programming languages are formal languages used to write computer programs. They define the syntax and semantics of instructions.
Programming paradigms are different styles of programming, each with its own approach to problem-solving and program structure. Examples include procedural, object-oriented, logic, and functional.
Algorithms are step-by-step procedures for solving a specific problem. Efficient algorithms are crucial for good program performance.

Programming Languages

Different programming languages have different strengths and weaknesses, suited to specific tasks and problems.
Popular programming languages include Python, Java, JavaScript, C++, C#, and others. Each has a unique syntax and features.
The choice of language depends on factors such as the intended use (web development, data science, game development, etc.), the developer's expertise, performance requirements, and available libraries/frameworks.
Programs are written using specific keywords, variables, data structures, control flow structures, and functions defined by the chosen language.

Software Development Lifecycle (SDLC)

The SDLC is a systematic approach to software development. This involves several phases: requirements gathering, design, implementation, testing, deployment, and maintenance.
Requirements gathering entails defining the problem, objectives, and functionalities the program must address.
Design involves creating detailed blueprints of the program's structure, algorithms, and data flow.
Implementation involves translating the design into actual code using a programming language.
Testing entails validating the correctness and robustness of the program through various tests (unit tests, integration tests, system tests, etc.).
Deployment involves releasing the program to users.
Maintenance involves fixing bugs, updating functionalities, and adapting to evolving needs.

Data Structures and Algorithms

Data structures organize data in a computer's memory. Examples include arrays, linked lists, stacks, queues, trees, and graphs. Each data structure has its advantages and disadvantages in terms of storage and access speed.
Algorithms are step-by-step procedures for solving problems using data structures. Algorithms determine how data is manipulated and processed.
Common tasks using algorithms include sorting, searching, and graph traversal.

Programming Paradigms

Procedural programming organizes programs into procedures (or functions). It focuses on actions to be performed.
Object-oriented programming (OOP) organizes software design around objects, which encapsulate data and methods (functions) operating on that data. Core principles include encapsulation, inheritance, and polymorphism.
Functional programming treats computation as the evaluation of mathematical functions and avoids changing state and mutable data.
Logic programming uses logical statements and rules to define problems and solve them.

Debugging and Testing

Debugging is the process of identifying and fixing errors (bugs) in computer programs. Techniques include using debuggers, logging, and applying systematic troubleshooting strategies.
Testing helps ensure programs function correctly and meet specifications. Various testing methods exist, including unit tests, integration tests, and system tests.
Well-tested code is more reliable, maintainable, and less prone to errors as programs grow.

Version Control

Version control systems (e.g., Git) are crucial for collaborative software development.
They track changes to code over time and allow multiple developers to work on the same project simultaneously.
Version control promotes code management by enabling developers to revert to earlier versions, branch off, merge changes, and resolve conflicts effectively.

Popular Tools and Technologies

Integrated Development Environments (IDEs) provide a comprehensive environment for developing, writing, debugging, and running code (e.g., VS Code, Eclipse, IntelliJ).
Version control systems (e.g., Git) track changes to source code, crucial for collaborative projects.
Web development frameworks (e.g., React, Angular, Vue.js) provide a structure for building user interfaces and web applications. Their use simplifies building complex web apps.
Different languages use different libraries and frameworks (e.g., NumPy/Pandas for Python, specific libraries for C++ game development).
