    Study Notes

    Computer Programming Lecture Notes

    • Computer programming is the process of designing, writing, testing, debugging, and maintaining the source code of computer programs.
    • Programming paradigms are a way to categorize programming languages based on their programming style.
    • Common paradigms include imperative, procedural, declarative, structured, functional, object-oriented, event-driven, and logic.
    • Imperative programming is focused on defining a linear procedure or set of programming statements. These statements are written sequentially to tell the computer what to do step-by-step.

    Programming Paradigms

    • Programming paradigms are a way to classify programming languages.
    • Some languages fit only one paradigm, while others may use elements of multiple paradigms.

    Common Paradigms

    • Imperative: Control flow is an explicit sequence of commands. Procedures are executed in a specific order.
    • Procedural: Applies a series of instructions to solve the problem in a step-by-step manner. Uses modularity (procedures/ routines) for organization.
    • Declarative: Programs express the desired result without specifying how to get it. The program describes what needs to be done, not the details of how to execute it.
    • Structured: Relies on clean, structured control flow with no "goto" statements. This reduces program complexity.
    • Functional: Computation proceeds through (nested) function calls. It avoids changing state and focuses on immutable data.
    • Object-Oriented: Models the problem/world by using entities called objects. Objects have attributes (data) and behaviors (code / functions – often called methods) and interact with other objects.
    • Event-Driven: Programs react to specific events that happen, like mouse clicks or sensor readings. The program waits for something to trigger an event then acts. Programs using event-driven programming have dynamic interaction.
    • Logic (Rule-Based): Defines a set of constraints, and an engine infers the solutions or answers to the questions. It's a form of declarative programming frequently used in Artificial Intelligence.

    Fundamental Idea of Object Oriented Programming Paradigms

    • Combine data (often called Attributes) and the functions that operate on that data into a single unit (called an Object)
    • Data is hidden within the object to prevent unintended changes.
    • Access or modify data via special functions called Methods that are part of the Object
    • Calling an object's methods is referred to as sending a message to the object.
    • Encapsulation and data hiding are essential to OOP.

    Object-Oriented Programming Paradigm

    • Programs are modeled as a web of interacting objects.
    • Objects communicate with each other by sending messages.
    • This approach to software organization is fundamental to OOP.

    Computer Programming 1: Lecture 2

    • Variables: Symbols representing a storage location in the computer's memory.
    • Data types (e.g., int, double, char).
    • Constants: Expressions with a fixed value (e.g., 10, 'a', "Hello").
    • Operators: Symbols that perform operations on data (e.g., +, -, *, /).
    • Basic Input/Output (I/O): Methods to get input from and provide output to the user or other sources such as a file.

    Computer Programming 1: Lecture 3

    • Control Structures: The fundamental blocks of programs that regulate the order in which instructions are executed
    • Three basic structure types:
    • Sequential: Statements execute in the order in which they appear.
    • Selection: Statements are skipped or executed conditionally depending on a condition. Often achieved using 'if' statements.
    • Repetition: Statements are executed repeatedly as long as a condition is met. Achieved using loops such as 'while', 'do-while', and 'for'.

    Computer Programming 1: Lecture 4

    • Iteration Structures (Loops): Structures used to execute a block of code repeatedly.
    • There are three main types:
    • While Loop: The code block is executed as long as the controlling condition remains true.
    • Do-While Loop: The code block is executed at least once and continues to be executed as long as the condition is true.
    • For Loop: The code block is executed based on an initialization, a controlling condition and an update increment.

    Computer Programming 1: More Details

    • More details about specific C++ concepts (functions, parameter passing, exceptions, etc.) can be found in the lecture slides (including any examples).

    C++ Keywords & Data Types

    • Specific keywords, data types, and additional details about C++ can be found in the lecture slides and/or textbook.

    File Input/Output (I/O)

    • Methods for managing data within files (including how to open, read, write, and close them), and file open modes that can be used, may be found in the lecture slides/textbook.

    OOP (Object-Oriented Programming) Concepts

    • Classes: Data types that encapsulate attributes (data) and operations (functions, often called methods).
    • Objects: Actual instances of a class.
    • Data Abstraction: Hiding the internal implementation details of a class while exposing a simplified interface.
    • Encapsulation: Bundling of data members and member methods within a class.
    • Inheritance: Creating new classes (derived classes) based on existing ones (base classes).
    • Polymorphism: Objects of different classes can respond to the same method call in their own particular way
    • Dynamic Binding: A mechanism by which the correct method to invoke is tied during runtime rather than at compile time.
    • Message Passing: Objects communicate by sending messages to each other, and this communication happens through the use of methods (functions belonging to class objects).
    • Methods (Functions of objects): Code within an object to perform certain operations on data of an object.
