C Linked List Implementations for Student Data

This document presents two distinct C language implementations for managing student records using linked lists: a singly linked list and a circular linked list. Both examples demonstrate fundamental data structure operations such as adding, deleting, searching, and displaying student information.

1. Singly Linked List Implementation

This section details a student management system built using a singly linked list. Students are stored in ascending order of their roll numbers, and duplicate roll numbers are prevented.

Core Structure and Global Head

The Student structure defines the data for each node, including roll number, total marks, average, and a pointer to the next student. The head pointer always... Continue reading "C Linked List Student Data Management Systems" »

Introduction to OOP Concepts

This document presents practical code examples demonstrating fundamental Object-Oriented Programming (OOP) concepts in both Delphi (Pascal) and C++. It covers class definitions, object instantiation, properties, events, static members, inheritance, polymorphism, memory management, and exception handling.

Delphi Object-Oriented Programming

The following Delphi code illustrates the creation of classes, properties, events, and static members, along with their usage in a console application.

program Cheat;
{$APPTYPE CONSOLE}

uses
  SysUtils, Classes;

type
  TNotify = procedure(Sender: TObject) of object;

  TEngine = class
    procedure Start;
    begin
      Writeln('Engine Started');
    end;
  end;

  TCar = class

Understanding Passive Voice and Reporting Verbs

1. Passive Voice with Modal Verbs

• Passive with Modal Verbs (Present):

  Subject + modal + be + past participle

  Example: This jacket should be worn in cold weather.

• Passive with Modal Verbs (Past):

  Subject + modal + have + been + past participle

  Example: My phone must have been stolen. (used to express a past situation)

2. Passive Voice with Infinitive or Verb + -ing

• Passive Infinitive:

  Subject + verb + to be + past participle

  Example: She hopes to be chosen for the school concert.

• Passive Verb + -ing (Gerund):

  Subject + verb + being + past participle

  Example: I hate being told what to eat.

3. Passive Voice with Reporting Verbs (General Beliefs)

• Passive with Reporting Verbs (to talk about general beliefs):

  Example:

Probability Concepts

• Union of Events: P(A∪B) = P(A) + P(B) - P(A∩B)
• Complement of an Event: P(A^c) = 1 - P(A)
• Intersection of B and Complement of A: P(B∩A^c) = P(B) - P(A∩B)
• Conditional Probability: P(B|A) = P(A∩B) / P(A)
• Intersection of Complements: P(A^c∩B^c) = 1 - P(A∪B)
• Mutually Exclusive Events: P(A∩B) = 0
• Independent Events: P(A∩B) = P(A)·P(B)

Binomial Distribution Parameters

• Mean (μ): μ = n·p
• Standard Deviation (σ): σ = √(n·p·q)

Binomial Distribution

Notation: B(n, p)

Probability Mass Function: P(X=a) = (ⁿ_a) p^a q^n-a

Where:

• n = number of trials
• p = probability of success
• q = complement of p (q = 1-p)

Normal Distribution

Notation: X ∼ N(μ, σ)

Important Probabilities:

• P(Z < a) or P(Z > a) can be found using a standard normal

Core Concepts in Compiler Design

Compiler

Compiler: Translates entire source code to target code before execution. It requires a full parse and upfront error checking, then executes the generated target code.

Interpreter

Interpreter: Executes source code incrementally (line-by-line or statement-by-statement). It translates and executes on the fly, and may partially execute ill-formed programs until an error is encountered.

LVar vs. x86 Architecture

LVar: Features nested expressions, implicit control flow (represented by an Abstract Syntax Tree - AST), and an unlimited number of logical variables.

x86: Characterized by flat instructions, atomic operands (registers/memory), explicit control flow (jumps), and a limited set of registers. Compilation passes... Continue reading "Core Concepts in Compiler Design and Language Runtime" »

Cranial Synchondroses and Closure Times

Synchondroses are temporary cartilaginous joints crucial for craniofacial growth:

1. Spheno-occipital: Located between the occipital and sphenoidal base. Closes at 18–20 years old.
2. Inter-sphenoidal: Located between the anterior and posterior sphenoid. Closes before birth (prenatally).
3. Spheno-ethmoidal: Located between the sphenoidal and ethmoidal bones. Closes at 5–7 years old.
4. Intra-occipital: Located inside the occipital bone. Closes at 3–5 years old.

Etiology of Local Malocclusion

Local factors contributing to malocclusion are categorized as Hereditary, Acquired, or Other:

• Hereditary Manifestations:
  • Skeletal manifestation
  • Soft tissue manifestation
  • Dental manifestations
• Acquired Factors:
  • Trauma (Macro trauma,
