Study Notes: Programming Techniques

Fundamental Programming Paradigms

• Procedural: Focuses on procedures or functions that operate on data. Sequence of steps to solve a problem (Example: C).

• Object-Oriented: Organizes software design around objects, which combine data and methods (functions) that operate on that data. Real-world entities as programming constructs (Example: Java, Python).

• Functional: Emphasizes the evaluation of mathematical functions. Avoids changing state or side effects, instead focuses on immutability & reusability. (Example: Lisp, Haskell).

• Logical: Based on formal logic, suitable for problems that can be stated in terms of facts, rules, and queries. (Example: Prolog).

• Graphical / visual: The use of graphical elements to compose and manipulate procedures like in flowcharts or visual programming environments.

Programming Languages

• Different languages excel at different tasks:
• Python: general purpse, excellent for scripting, data analysis
• Java: object-oriented, large enterprise applications
• C++: system programming, performance-critical applications.
• C#: primarily Windows applications.
• JavaScript: front-end web development.

Data Structures

• Arrays: Ordered collections of elements of the same data type. Efficient access by index but not for insertion/deletion.
• Linked Lists: Ordered collections of data where each element (node) holds a reference to the next element. Enables dynamic sizing.
• Stacks: LIFO (Last-In, First-Out) data structure. Useful for function calls, undo operations.
• Queues: FIFO (First-In, First-Out) data structure. Useful for managing tasks in order of arrival.

Algorithms

• Algorithms are step-by-step procedures for solving a specific problem.
• Efficiency is measured in time and space complexity.
• Common algorithms include searching (linear, binary), sorting (bubble, merge, quick), graph algorithms (traversal, shortest paths).

Problem-Solving

• Decompose a problem into smaller manageable pieces.
• Choose the appropriate data structures and algorithms for solving the problem.
• Test your code thoroughly to ensure correctness.

Debugging

• Identify the source of the error.
• Use debugging tools to step through your code.
• Review your code for syntax and logical errors.
• Employ logging to effectively trace the execution flow.

Code Readability

• Use meaningful variable names.
• Write well-commented code.
• Break down code into reusable functions.
• Follow consistent coding style.

Software Development Life Cycle (SDLC)

• Phases include planning, design, development, testing, deployment, and maintenance.
• Iterative approach with feedback loops can improve quality and efficiency during development.
• Emphasizing testing at each phase is critical for quality assurance.

Tools

• Compilers: translate source code into machine code.
• Interpreters: execute source code directly.
• Debuggers: help identify and fix errors in code.
