C++ classes tutorials
This document discusses C++ classes and object-oriented programming. It defines classes as user-defined types that encapsulate data and functions. Classes allow programmers to model real-world entities as objects. The document provides examples of class definitions, member functions, constructors, destructors, and accessing class members. It explains that classes simplify programming by promoting code reuse and hiding implementation details behind interfaces.
C++ classes tutorials
This document discusses C++ classes and object-oriented programming. It defines classes as user-defined types that encapsulate data and functions. Classes allow programmers to model real-world entities as objects with attributes and behaviors. The document provides examples of class definitions, member access specifiers, constructors, member functions, and accessing class members. It demonstrates how classes are used to define objects and encapsulate data in C++.
Oo ps
Object-oriented programming uses objects with characteristics and behaviors defined in classes. A class defines the data members and methods of an object. Data members can be declared as private or public, with private only accessible within the class. Constructors initialize objects, and destructors handle cleanup. Classes encapsulate data and behavior into reusable objects.
JRuby: Apples and Oranges
The document discusses JRuby, an implementation of the Ruby programming language that runs on the Java Virtual Machine. It provides an overview of JRuby, including its goals of helping with day-to-day development. The author introduces himself and his experience with Ruby, Java, and JRuby. He then covers topics like installing JRuby, integrating Java and Ruby code, using JRuby for scripting and build tools, and testing with JRuby. Web development with Ruby on Rails on JRuby is also mentioned.
Code level change propagation in virtual platform
The document discusses code-level change propagation in a virtual platform for managing software variants. It describes two operators - SynchronizeAsset and IntegrateAsset - that were developed to address issues with existing non-code based propagation. SynchronizeAsset allows two-way synchronization of code changes between assets while wrapping changes in presence conditions and tracking variation points. IntegrateAsset allows one-way propagation of changes from a source to target asset, also wrapping changes in presence conditions. The effectiveness of these operators is evaluated in a developer study where tasks are timed both with and without the operators.

Abstract Classes Interface Exceptional Handling Java
1. The document describes a lab report for an Object Oriented Programming class. It includes 3 questions that involve inheritance, interfaces, exceptions, and calculating percentages and areas of shapes.
2. The first question involves creating classes for two students (StudentA and StudentB) that inherit from an abstract Marks class and calculate percentage scores.
3. The second question defines interfaces for drawing and shapes, and classes for rectangle, circle, and square that implement the interfaces and calculate areas.
4. The third question defines a Division class that takes two numbers as input, handles exceptions when dividing by zero, and divides the numbers until the second number is zero.

1- Create a class called Point that has two instance variables, defi.pdf
1- Create a class called Point that has two instance variables, defined as private, as follows: An x
coordinate and a y coordinate of type integer.
a) Write two constructors for the Point class as follows: A default constructor that sets the class
instance variables to zero and a constructor that receives two integer values and sets the instance
variables to them.
b) Write the set and get methods for the Point class to set and return the values of its instance
variables.
c) Write a toString() method for the Point class that prints the class name (Point) and the value of
its instance variables.
2- Create three classes called Circle, Rectangle and Square with the following properties:
- The Circle class has two instance variables – a position of type Point (the class that you just
created above) and a radius of type double. The instance variables position and radius specify the
position of the center and radius of the circle, respectively.
- The Rectangle class has three instance variables – a position of type Point (the class that you
just created above), a length and a width of type double. The instance variables position, length
and width specify the position of the top left corner, length and width of the rectangle,
respectively.
- The Square class has two instance variables – a position of type Point (the class that you just
created above) and a lengthof type double. The instance variables position andlength specify the
position of the top left corner and length of the square, respectively.
For each of the Circle, Rectangle andSquare classes do the following:
a) Define the instance variables as private.
b) Write two constructors for each class as follows: A default constructor that sets the instance
variables to zero and a constructor that receives values for the instance variables and sets them.
c) Write the set and get methods for each class to set and return the values of their instance
variables. For example, one of the get methods would return a Point.
d) Write a toString() method for each class that prints the class name (Circle, Rectangle or
Square) and the value of its instance variables.
e) Write two methods called getPerimeter() and getArea() for each class, which calculate and
return the perimeter and area of the class, respectively. For example, the getArea() method of the
Square class returns the area of the Square object.
3- Test the above classes by writing a class called GeometricTest.java that does the following:
- Creates instances of the Circle, Rectangle and Square classes as follows:
- Circle: positioned at x = 7, y = 3 and the radius = 4.5.
- Rectangle: positioned at x = 3, y = -1 and the length = 4.0 and width = 6.0.
- Square: positioned at x = 5, y = 8 and the length = 2.0.
- Prints each of the above objects.
- Changes the length of the Square object to 5.0.
- Prints the perimeter and area of each of each of the above objects.
- Compares the x coordinates of the Square and Rectangle classes and prints a message
spec.

Geopy module in python
The document discusses the geopy module in Python, which is used for geocoding and geolocation. It allows users to geolocate addresses, cities, countries and landmarks into geographic coordinates and vice versa. The geopy module utilizes third party geocoders like Google Maps, Bing Maps and Nominatim. It discusses how to install, import and use the module to geocode and reverse geocode locations. Various methods like geocode(), reverse() and functions to convert between distance and angle units are also covered.
Csphtp1 10
The document discusses object-oriented programming concepts like polymorphism. It includes:
- An introduction to polymorphism and how it allows programs to handle related classes generically and be easily extensible.
- Examples of polymorphism including a shape hierarchy with classes like Quadrilateral, Rectangle, etc. and a space object hierarchy with classes that all implement a DrawYourself method.
- Details about abstract classes and how they provide base classes that concrete classes inherit from while requiring the concrete classes to implement abstract methods and properties.
- A case study demonstrating inheritance and polymorphism using abstract base class Shape and concrete classes Point2, Circle2, and Cylinder2 that inherit from Shape.

The document discusses object-oriented programming concepts like polymorphism. It includes:
- An introduction to polymorphism and how it allows programs to handle related classes generically and be easily extensible.
- Examples of polymorphism including a shape hierarchy with classes like Square and Circle overriding a perimeter method, and a space object hierarchy with classes overriding a DrawYourself method.
- Details about abstract classes and how they provide base classes that concrete classes inherit from, including an example abstract Shape class and derived Point2, Circle2 classes.
Csphtp1 09
The document discusses object-oriented programming concepts like inheritance, base classes, and derived classes. It provides code examples to illustrate inheritance relationships between classes like Point, Circle, and Cylinder. The code defines base classes like Point and derived classes like Circle that inherit properties and methods from their base classes. Tests are provided to create objects from derived classes and demonstrate inherited functionality.

It provides code examples to illustrate inheritance relationships between classes like Point, Circle, and Cylinder. The code defines base classes like Point and derived classes like Circle that inherit properties and methods from their base classes. The examples show how to define constructors, properties, and methods in base and derived classes and call methods on derived class objects to demonstrate polymorphism.
10_interfacesjavaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa.pdf
The document discusses interfaces in Java. It explains that an interface defines a contract that specifies certain methods that classes implementing the interface must define. Interfaces allow for polymorphism, as classes implementing the same interface can be used interchangeably. Common Java interfaces like Comparable and interfaces defining common data structures like List are presented as examples.
ES2015 Modules
This document compares different module systems for JavaScript including CommonJS, AMD, and ES2015 modules. It shows examples of how to export and import values between modules using these different systems. CommonJS exports values using module.exports while AMD uses a define function. ES2015 modules introduce new export and import keywords and allow for named exports, default exports, namespaced imports, and export/import aliases.

The document discusses asynchronous code in JavaScript using generators and the co library. It shows examples of getting a username and user object asynchronously using callbacks, promises, and generators. It also demonstrates a simple Koa app that returns "Hello World" and uses a generator to find and return books from a database.
Object - Oriented Programming: Inheritance
The document discusses object-oriented programming concepts like inheritance, subclasses, and superclasses. It provides examples of inheritance hierarchies for different classes like Shapes, CommunityMembers, and BankAccounts. The key points are:
- Inheritance allows subclasses to inherit and customize behaviors from superclasses for code reusability.
- Subclasses are more specialized groups of objects that inherit data and behaviors from their superclasses.
- Java supports single inheritance but not multiple inheritance.
- Relationships between superclasses and subclasses form a hierarchical tree structure.
- Access modifiers like private and protected determine whether subclass instances can access members of superclasses.

Martian Cubics and Unit Testing
You must implement all of the data members and methods described below. RAM is more
limited on NASA missions than on your home computer, so you may NOT add any instance
variables or static variables to this class other than those described below. You may add methods
of your own, as long as they are private. The data type class you are writing is a very general
class that could be of use in a wide variety of projects at NASA in their Mars research, so take
care in your work!
Implement
eval -- this method takes one parameter (DoubleWithAppx), evaluates the Martian cubic at the
point represented by the parameter and returns a DoubleWithAppx representing the result of that
evaluation. (i.e., if your Martian cubic is 5x^3-3x^2+2x+4, and you call eval(5), it should return
564.)
My Code:
public class MartianCubic {
private final DoubleWithAppx a ;
private final DoubleWithAppx b;
private final DoubleWithAppx c;
private final DoubleWithAppx d;
public MartianCubic() {
a = new DoubleWithAppx(0);
b = new DoubleWithAppx(0);
c = new DoubleWithAppx(0);
d = new DoubleWithAppx(0);
}
public MartianCubic(DoubleWithAppx dIn) {
d = dIn;
a = new DoubleWithAppx(0);
b = new DoubleWithAppx(0);
c = new DoubleWithAppx(0);
}
public MartianCubic(DoubleWithAppx cIn, DoubleWithAppx dIn) {
c = cIn;
d = dIn;
a = new DoubleWithAppx(0);
b = new DoubleWithAppx(0);
}
public MartianCubic(DoubleWithAppx bIn, DoubleWithAppx cIn, DoubleWithAppx dIn) {
this.b = bIn;
this.c = cIn;
this.d = dIn;
a = new DoubleWithAppx(0);
}
public MartianCubic(DoubleWithAppx aIn, DoubleWithAppx bIn, DoubleWithAppx cIn,
DoubleWithAppx dIn) {
this.a = aIn;
this.b = bIn;
this.c = cIn;
this.d = dIn;
}
public MartianCubic(MartianCubic other) {
this(
other.getA(),
other.getB(),
other.getC(),
other.getD()
);
}
public DoubleWithAppx getA() {
return a;
}
public DoubleWithAppx getB() {
return b;
}
public DoubleWithAppx getC() {
return c;

JRuby: Enhancing Java Developers Lives
Hiro Asari's Devoxx 2011 presentation
Presentation description:
Java developers wear many hats: they manage builds, develop applications, write command-line scripts, and must master all tiers. If only there were a way to make these tasks simple and fun.
Enter JRuby.
Build engineers can write or enhance builds with Ruby, never losing a thing they depend on from Ant or Maven. Ruby offers several elegant testing options that work great with JRuby. Web developers can create Rails applications in minutes, effortlessly incorporating the latest Web technologies while taking advantage of the existing Java libraries. JRuby supports binding native libraries with FFI (foreign function interface). Command-line scripts? They're easy with JRuby's system-level features.
Come to this session to learn how JRuby makes you a happy developer.
Abstract Classes Interface Exceptional Handling Java
1. The document describes a lab report for an Object Oriented Programming class. It includes 3 questions that involve inheritance, interfaces, exceptions, and calculating percentages and areas of shapes.
2. The first question involves creating classes for two students (StudentA and StudentB) that inherit from an abstract Marks class and calculate percentage scores.
3. The second question defines interfaces for drawing and shapes, and classes for rectangle, circle, and square that implement the interfaces and calculate areas.
4. The third question defines a Division class that takes two numbers as input, handles exceptions when dividing by zero, and divides the numbers until the second number is zero.

1- Create a class called Point that has two instance variables, defi.pdf
1- Create a class called Point that has two instance variables, defined as private, as follows: An x
coordinate and a y coordinate of type integer.
a) Write two constructors for the Point class as follows: A default constructor that sets the class
instance variables to zero and a constructor that receives two integer values and sets the instance
variables to them.
b) Write the set and get methods for the Point class to set and return the values of its instance
variables.
c) Write a toString() method for the Point class that prints the class name (Point) and the value of
its instance variables.
2- Create three classes called Circle, Rectangle and Square with the following properties:
- The Circle class has two instance variables – a position of type Point (the class that you just
created above) and a radius of type double. The instance variables position and radius specify the
position of the center and radius of the circle, respectively.
- The Rectangle class has three instance variables – a position of type Point (the class that you
just created above), a length and a width of type double. The instance variables position, length
and width specify the position of the top left corner, length and width of the rectangle,
respectively.
- The Square class has two instance variables – a position of type Point (the class that you just
created above) and a lengthof type double. The instance variables position andlength specify the
position of the top left corner and length of the square, respectively.
For each of the Circle, Rectangle andSquare classes do the following:
a) Define the instance variables as private.
b) Write two constructors for each class as follows: A default constructor that sets the instance
variables to zero and a constructor that receives values for the instance variables and sets them.
c) Write the set and get methods for each class to set and return the values of their instance
variables. For example, one of the get methods would return a Point.
d) Write a toString() method for each class that prints the class name (Circle, Rectangle or
Square) and the value of its instance variables.
e) Write two methods called getPerimeter() and getArea() for each class, which calculate and
return the perimeter and area of the class, respectively. For example, the getArea() method of the
Square class returns the area of the Square object.
3- Test the above classes by writing a class called GeometricTest.java that does the following:
- Creates instances of the Circle, Rectangle and Square classes as follows:
- Circle: positioned at x = 7, y = 3 and the radius = 4.5.
- Rectangle: positioned at x = 3, y = -1 and the length = 4.0 and width = 6.0.
- Square: positioned at x = 5, y = 8 and the length = 2.0.
- Prints each of the above objects.
- Changes the length of the Square object to 5.0.
- Prints the perimeter and area of each of each of the above objects.
- Compares the x coordinates of the Square and Rectangle classes and prints a message
spec.

Geopy module in python
The document discusses the geopy module in Python, which is used for geocoding and geolocation. It allows users to geolocate addresses, cities, countries and landmarks into geographic coordinates and vice versa. The geopy module utilizes third party geocoders like Google Maps, Bing Maps and Nominatim. It discusses how to install, import and use the module to geocode and reverse geocode locations. Various methods like geocode(), reverse() and functions to convert between distance and angle units are also covered.

The document discusses object-oriented programming concepts like polymorphism. It includes:
- An introduction to polymorphism and how it allows programs to handle related classes generically and be easily extensible.
- Examples of polymorphism including a shape hierarchy with classes like Quadrilateral, Rectangle, etc. and a space object hierarchy with classes that all implement a DrawYourself method.
- Details about abstract classes and how they provide base classes that concrete classes inherit from while requiring the concrete classes to implement abstract methods and properties.
- A case study demonstrating inheritance and polymorphism using abstract base class Shape and concrete classes Point2, Circle2, and Cylinder2 that inherit from Shape.

10_interfacesjavaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa.pdf
The document discusses interfaces in Java. It explains that an interface defines a contract that specifies certain methods that classes implementing the interface must define. Interfaces allow for polymorphism, as classes implementing the same interface can be used interchangeably. Common Java interfaces like Comparable and interfaces defining common data structures like List are presented as examples.
ES2015 Modules
This document compares different module systems for JavaScript including CommonJS, AMD, and ES2015 modules. It shows examples of how to export and import values between modules using these different systems. CommonJS exports values using module.exports while AMD uses a define function. ES2015 modules introduce new export and import keywords and allow for named exports, default exports, namespaced imports, and export/import aliases.

It also demonstrates a simple Koa app that returns "Hello World" and uses a generator to find and return books from a database.
Object - Oriented Programming: Inheritance
The document discusses object-oriented programming concepts like inheritance, subclasses, and superclasses. It provides examples of inheritance hierarchies for different classes like Shapes, CommunityMembers, and BankAccounts. The key points are:
- Inheritance allows subclasses to inherit and customize behaviors from superclasses for code reusability.
- Subclasses are more specialized groups of objects that inherit data and behaviors from their superclasses.
- Java supports single inheritance but not multiple inheritance.
- Relationships between superclasses and subclasses form a hierarchical tree structure.
- Access modifiers like private and protected determine whether subclass instances can access members of superclasses.

Martian Cubics and Unit Testing
You must implement all of the data members and methods described below. RAM is more
limited on NASA missions than on your home computer, so you may NOT add any instance
variables or static variables to this class other than those described below. You may add methods
of your own, as long as they are private. The data type class you are writing is a very general
class that could be of use in a wide variety of projects at NASA in their Mars research, so take
care in your work!
Implement
eval -- this method takes one parameter (DoubleWithAppx), evaluates the Martian cubic at the
point represented by the parameter and returns a DoubleWithAppx representing the result of that
evaluation. (i.e., if your Martian cubic is 5x^3-3x^2+2x+4, and you call eval(5), it should return
564.)
My Code:
public class MartianCubic {
private final DoubleWithAppx a ;
private final DoubleWithAppx b;
private final DoubleWithAppx c;
private final DoubleWithAppx d;
public MartianCubic() {
a = new DoubleWithAppx(0);

d = dIn;
a = new DoubleWithAppx(0);
b = new DoubleWithAppx(0);

DoubleWithAppx dIn) {
this.a = aIn;
this.b = bIn;
this.c = cIn;

London/dispersion/van der Waals forces - these are weak interactions that occur in
a matter of nanoseconds when one atom in a bond temporarily takes more of the electron density
than the other one, causing a temporary dipole - i.e. this can happen even when you have a C-H

[H2SO4] = 0 because H2SO4 is a strong acid. first consider Ka2.pdf
[H2SO4] = 0 because H2SO4 is a strong acid.
first consider Ka2:
Ka2 = [H+][SO42-]/[HSO4-] = 1.3X10^-2
From the starting condition, let x = [SO42-]. Then, [H+] = 0.14+ x, and [HSO4-] = 0.14 - x.
now the value in Ka2 expression:
1.3X10^-2 = (0.14 +x) (x) / (0.14-x)
1.82 X10^-3 - 1.3X10^-2x = 0.14 x + x^2
x^2 + 0.153 x – 1.82 X10^-3 = 0
solve the above equation we will get;
x = 0.0111
thus;
x = [SO42-]=0.0111
Then, [H+] = 0.14 + 0.0111 = 0.1511
, and [HSO4-] = 0.14 – x = 0.14- 0.0111= 0.1289

myocarditis. Given all this evidence, you asked the parents if they had given their children
routine vaccinations. When they said no, you knew exactly what it was. Describe the cause of
Ashley’s illness and how you know.
ans: Ashley\'s illness is due to the bacterial infection caused by the bacteria Corynebacterium
diptheriae.This is causing Ashley to suffer.This bacteria causes infection which led to die the
cells of tonsils and throat.Thats why she is having throat infection.And as they have skipped the
vaccination process she got infected as she has less resistance or immunity.

Implementation of security measures , Network monitoring, Recovery, reporting and final is
follow up.
Action or an event never happens on a prescribed or convenient time hence a its always to have a
checklist in place and be prepared like what time the issue happend,who reported etc.
Then to analyse the situation and which might requite forensics software and other environment
support which helps in analysis, gathering and understanding of evidence.
And the most important part is duplication which is accomplised by creating duplicate bit by bit
to a hard drive.And there are basically two approaches of doing so one is software based and
another is hardware based.And in this place hardware based approach has upper hand as it
provides speed and integrity.Also it provided the confidence of less risk of data gettting
corrupted.

The FCPA established criminal and civil penalties for unlawful payme.pdf
The FCPA established criminal and civil penalties for unlawful payments or bribes (or promises
of payments) to foreign officials for the purpose of obtaining or keeping business, either directly
or indirectly or through agents, to influence any act or decision or to secure any improper
advantage in order to obtain or retain business.
The FCPA applies to foreign companies listed on a US exchange or required to file accounts
with the SEC, as well as by US corporations or US nationals. It also applies to foreign nationals
who cause an act in the US (such as a wire transfer or establishment of an e-mail server in the
US) which furthers an FCPA offence.
Accounting requirements apply to companies required to file periodic reports with the SEC.
Requirements cover both systems of internal control and adequate record keeping – non-
compliance can be a criminal offence.
The US federal authorities are pursuing cases aggressively and assessing large penalties for the
violations of FPCA.
Companies which may be subject to the FCPA are strongly advised to conduct suitable due
diligence on intermediaries, agents or local partners. Local U.S. Embassies or Consulates can
provide suitable profiles under the International Company Profile (ICP) service.
Managers and lawyers in most companies want to believe they work for clean, ethical
organizations that hire law-abiding employees. This positive bias often blinds US business
people to the reality of international business, where bribes, kickbacks, and false or unrecorded
transactions are common. Corrupt activity also exists in the US of course, but it is more difficult
to understand what is going on in foreign countries when your US managers have little or no
language ability or cultural context.
Some US business people believe and frequently say \"Everyone knows you can\'t do business in
(Mexico, China, India, Russia - pick a country) without paying bribes. It is part of their culture. It
is crazy to have a US law that makes paying bribes in foreign countries illegal in the USA.\"
Even if that were true, the FCPA is part of the legal environment for international business.
Compliance is not optional because American management has a low opinion of foreign
government officials.
Corruption in international business is common and frequently ignored.
Investigation, prosecution and punishment under the FCPA is common.
Understand your company\'s risk of being involved in international bribery.
Your program requires a Standalone International Anti-corruption Compliance policy, and an
Executive who is Accountable for the “Tone at the Top”.
Train your board, management, employees and third parties who distribute your products
Know all the 3rd parties your company uses in business outside the USA and conduct due
diligence.
Establish a set of internal controls over company expenditures and assets.
Do not permit facilitating payments.
Plan for the likelihood you will have to conduct high quality international internal inves.

Spontaneous mutation rates depend on the rate at which DNA transcrip.pdf
Spontaneous mutation rates depend on the rate at which DNA transcription occurs. All the three
strains given in the question show a higher rate of spontaneous mutation because they have
effects in the mutS or mutL genes, which are involved in mismatch repair system.
In Salmonella A and B, during infectious stage, the DNA mutations occurs faster when
compared to E.coli, because DNA damage does not induce SOS response for DNA repair in
Salmonella.
The E.Coli strain has a better DNA repair system because the SOS response quickly responds to
the DNA damage during infectious phase.
E.coli strain has more permeable membrane compared to Salmonella.

pKa of H2PO4- is = 7.21According to Hendersons Equation ,pH = .pdf
pKa of H2PO4- is = 7.21
According to Henderson\'s Equation ,
pH = pKa + log ( [salt] /[acid])
= pKa + log ( [Na2HPO4] / [ KH2PO4 ] )
= 7.21 + log ( 0.135 / 0.185 )
= 7.21 - 0.14
= 7.07
Solution
pKa of H2PO4- is = 7.21
According to Henderson\'s Equation ,
pH = pKa + log ( [salt] /[acid])
= pKa + log ( [Na2HPO4] / [ KH2PO4 ] )
= 7.21 + log ( 0.135 / 0.185 )
= 7.21 - 0.14
= 7.07.

A Strategic Approach: GenAI in Education
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.
