Inheritance in C++
The capability of a class to derive properties and characteristics from another class is called Inheritance. Inheritance is one of the most important features of Object-Oriented Programming.
Inheritance is a feature or a process in which, new classes are created from the existing classes. The new class created is called “derived class” or “child class” and the existing class is known as the “base class” or “parent class”. The derived class now is said to be inherited from the base class.
When we say derived class inherits the base class, it means, the derived class inherits all the properties of the base class, without changing the properties of base class and may add new features to its own. These new features in the derived class will not affect the base class. The derived class is the specialized class for the base class.
Sub Class: The class that inherits properties from another class is called Subclass or Derived Class.
Super Class: The class whose properties are inherited by a subclass is called Base Class or Superclass
Why and when to use inheritance?
Consider a group of vehicles. You need to create classes for Bus, Car, and Truck. The methods fuelAmount(), capacity(), applyBrakes() will be the same for all three classes. If we create these classes avoiding inheritance then we have to write all of these functions in each of the three classes
Implementing inheritance in C++: For creating a sub-class that is inherited from the base class we have to follow the below syntax.
Derived Classes: A Derived class is defined as the class derived from the base class.
The genetic characters transmitted from parent to offspring, taken collectively.
Something, as a quality, characteristic, or other immaterial possession, received from progenitors or predecessors as if by succession.

An Approach to Detecting Writing Styles Based on Clustering Techniques
Authors:
-Devkinandan Jagtap

Institution:
VIIT Pune, India
Abstract:
This paper proposes a system to differentiate between human-generated and AI-generated texts using stylometric analysis. The system analyzes text files and classifies writing styles by employing various clustering algorithms, such as k-means, k-means++, hierarchical, and DBSCAN. The effectiveness of these algorithms is measured using silhouette scores. The system successfully identifies distinct writing styles within documents, demonstrating its potential for plagiarism detection.
Introduction:
Stylometry, the study of linguistic and structural features in texts, is used for tasks like plagiarism detection, genre separation, and author verification. This paper leverages stylometric analysis to identify different writing styles and improve plagiarism detection methods.
Methodology:
The system includes data collection, preprocessing, feature extraction, dimensional reduction, machine learning models for clustering, and performance comparison using silhouette scores. Feature extraction focuses on lexical features, vocabulary richness, and readability scores. The study uses a small dataset of texts from various authors and employs algorithms like k-means, k-means++, hierarchical clustering, and DBSCAN for clustering.
Results:
Experiments show that the system effectively identifies writing styles, with silhouette scores indicating reasonable to strong clustering when k=2. As the number of clusters increases, the silhouette scores decrease, indicating a drop in accuracy. K-means and k-means++ perform similarly, while hierarchical clustering is less optimized.
Conclusion and Future Work:
The system works well for distinguishing writing styles with two clusters but becomes less accurate as the number of clusters increases. Future research could focus on adding more parameters and optimizing the methodology to improve accuracy with higher cluster values. This system can enhance existing plagiarism detection tools, especially in academic settings.
Online aptitude test management system project report.pdfKamal Acharya
The purpose of on-line aptitude test system is to take online test in an efficient manner and no time wasting for checking the paper. The main objective of on-line aptitude test system is to efficiently evaluate the candidate thoroughly through a fully automated system that not only saves lot of time but also gives fast results. For students they give papers according to their convenience and time and there is no need of using extra thing like paper, pen etc. This can be used in educational institutions as well as in corporate world. Can be used anywhere any time as it is a web based application (user Location doesn’t matter). No restriction that examiner has to be present when the candidate takes the test.
Every time when lecturers/professors need to conduct examinations they have to sit down think about the questions and then create a whole new set of questions for each and every exam. In some cases the professor may want to give an open book online exam that is the student can take the exam any time anywhere, but the student might have to answer the questions in a limited time period. The professor may want to change the sequence of questions for every student. The problem that a student has is whenever a date for the exam is declared the student has to take it and there is no way he can take it at some other time. This project will create an interface for the examiner to create and store questions in a repository. It will also create an interface for the student to take examinations at his convenience and the questions and/or exams may be timed. Thereby creating an application which can be used by examiners and examinee’s simultaneously.
Examination System is very useful for Teachers/Professors. As in the teaching profession, you are responsible for writing question papers. In the conventional method, you write the question paper on paper, keep question papers separate from answers and all this information you have to keep in a locker to avoid unauthorized access. Using the Examination System you can create a question paper and everything will be written to a single exam file in encrypted format. You can set the General and Administrator password to avoid unauthorized access to your question paper. Every time you start the examination, the program shuffles all the questions and selects them randomly from the database, which reduces the chances of memorizing the questions.
Using recycled concrete aggregates (RCA) for pavements is crucial to achieving sustainability. Implementing RCA for new pavement can minimize carbon footprint, conserve natural resources, reduce harmful emissions, and lower life cycle costs. Compared to natural aggregate (NA), RCA pavement has fewer comprehensive studies and sustainability assessments.

2. Inheritance:
The mechanism of deriving a new class from an old one is called Inheritance.
The old class is referred to as the base class.
The new one is called the derived class or subclass.
3. General form of defining a derived class
Syntax:
Class derived-class-name : visibility mode base-class-name
{
……..//
…….// members of derived class
…….//
};
The colon indicate that the derived-class-name is derived from the base-class-name. The visibility mode is
optional and, if present, may be either private or public. The default visibility mode is private.
Visibility mode specifies whether the features of the base class are privately derived or publicly derived.
4. Types of Inheritance
Single Inheritance
Multiple Inheritance
Hierarchical Inheritance
Multilevel Inheritance
Hybrid Inheritance
5. Single Inheritance
In single inheritance there exists single
base class and single derived class.
It is the most simplest form of
inheritance.
8. Multiple inheritance
Multiple inheritance occurs when a class
is inherit from more than one base class.
Derived class can inherit features from
multiple base classes using multiple
inheritance.
11. Hierarchical inheritance
In this type of inheritance, more than one sub
class is inherited from a single base class. i.e.
more than one derived class is created from a
single base class.
14. Multilevel inheritance
In this type of inheritance, a derived class is
created from another derived class.
The class C serves as a base class for the
derived class B, which in turn serves as a base
class for the derived class A. The class B as
intermediate base class since it provides a link
for the inheritance between A and C the chain
ABC is known as inheritance path.
Class C {………}; //base class
Class B: public C {………}; //B derived from C
Class A: public B {……}; //A derived form B
17. Hybrid inheritance
Hybrid inheritance is implemented by
combining more than one type of
inheritance. For example: combining
hierarchical inheritance and multiple
inheritance.
20. Virtual base class
Consider a situation where three kind of inheritance, namely, multilevel, multiple and
hierarchical inheritance, are involved. This is illustrated in the figure.
The ‘child’ has two direct base classes ‘parent1’ and
‘Parent2’ which themselves have a common base class
‘grand parent’. The ‘child’ inherits the traits of ‘grandparent’
via two separate paths. It can also inherits the base class
directly. The ‘grand parent’ is sometimes referred to as the indirect base class.
This means ‘child’ is inherit the same property twice. To remove this duplication we
declare the base class ‘grandparent’ as the virtual while declaring the direct or
intermediate base class as shown:
21. Syntax
class A //grandparent
{ …….};
Class B1:virtual public A //parent1
{……..};
Class B2:public virtual A //parent2
{…….};
Class C:public B1,public B2 //child
{…….}; //only one copy of A will be inherited
22. Abstract classes
An abstract class is one that is not used to create objects. An abstract class is
designed only to act as a base class (to be inherited by other classes). It is a design
concept in program development and provides a base upon which other classes may
be built.
The concept can be explained through a simple example of an abstract base class
vehicle which may be declared in a program for deriving LMV (light motor vehicle),HMV
(heavy motor vehicle) and TW(two wheeler) derived classes. A pure virtual function
spec() may be set the specification of LMV as per its four wheel and smaller engine
and that of HMV as per its eight or more wheels and relatively larger engine.
23. Example
Class vehicle //abstract base class
{ private:
Datatype d1,d2;
public:
virtual void spec()=0; //pure virtual funtion
};
Class LMV : public vehicle
{ public:
void spec(){ ……. } //LMV definition of spec function
};
24. Example
Class HMV : public vehicle
{ public:
void spec(){ …….. } HMV definition of spec function
};
Class TW : public vehicle
{ public:
void spec(){ …….. } //TW definition of spec function
};
25. Advantages of inheritance
Inheritance promote reusability. When a class inherits or derives another class, it
can access all functionality of inherited class.
Reusability enhanced reliability. the base class code is already tested and
debugged.
Inheritance helps to reduce code redundancy and supports code extensibility.
26. Disadvantages of inheritance
Inherited functions work slower than the normal function as there is indirection.
Improper use of inheritance lead to wrong solution.
Inheritance increases the coupling between base class and derived class. A change
in base class will affects all the child classes.
