The C++ programming language has a history going back to 1979, when Bjarne Stroustrup was doing work for his Ph.D. thesis. One of the languages Stroustrup had the opportunity to work with was a language called Simula, which as the name implies is a language primarily designed for simulations.

Everything about OOPs (Object-oriented programming) in this slide we cover the all details about object-oriented programming using C++. we also discussed why C++ is called a subset of C.
C++ is a general-purpose programming language. It has imperative, object-oriented and generic programming features, while also providing the facilities for low-level memory manipulation.
It is designed with a bias toward system programming (e.g., for use in embedded systems or operating system kernels), with performance, efficiency and flexibility of use as its design requirements. C++ has also been found useful in many other contexts, including desktop applications, servers (e.g. e-commerce, web search or SQL servers), performance-critical applications (e.g. telephone switches or space probes), and entertainment software. C++ is a compiled language, with implementations of it available on many platforms and provided by various organizations, including the FSF, LLVM, Microsoft and Intel.

This project is the first projects you will be working on this quart.pdfeyewaregallery
This project is the first projects you will be working on this quarter. There are a number of
objectives to this assignment. First, to start gaining experience in developing programs in C++.
Second, in case you haven’t already you are going to work in pairs to get the sense of
collaborative development of software. Third, because you are allowed to use any references you
find online, this assignment will help you get a sense for just how many sources for
programming in C++ are available via the web. Project specification: In this project you are
going to implement a word search engine using C++. The search engine would help users to
count number of occurrence of a word among given set of text files. Input specification: The
program takes as an input a set of files, containing of multiple words. Words can appear multiple
times in a single file or in different files. The input files should be stored in a dedicated directory
(e.g. /cs/class/cs24/project1/input) and loaded in memory upon program execution. Program
functionality: Upon execution, the program should load all the words from the input files in the
memory. The program should run until the user explicitly specifies “exit”. The following
functionality should be supported: 1. Count how many times a user specified word appears in the
files. 3. Display the name of input files and corresponding number of occurrences of the
specified word. Upon execution of you program, you should specify as input parameter the path
to a directory containing the input files. Below you can find the format specification:
$./wordsearch Examples for execution format: $./wordsearch /cs/class/cs24/project1/input Enter
word: cat If executed as specified above, the program should return the name of files that contain
word “cat” and the number of occurrences of the word in each file Implementation requirements:
First, you need to implement a class for an abstract data type, in which you are going to store
files in memory. This step is very specific, depending on the functionality of the program you are
developing. For the current implementation you are required to use linked lists. A basic layout of
the data structure you would need to implement is illustrated on the figure below: You need to
declare a class Word that would store a word and a pointer to the beginning of a linked list and
another class File that would store a file-name and number of times that the word occurred in this
file. The process of “loading files in the memory” consists of (i) creating an object of type Word
for each new word that occurs in the set of input files, (ii) appending this object to a linked list
(e.g. the green linked list from the picture), (iii) creating an object File for each occurrence of the
word in a file and (iv) updating the corresponding (blue) linked list with the object File. Once
you have the files loaded in such structure, the searching would be as easy as finding the queried
word in the “green” linked list and tracing.

A nuclear weapon is an explosive device that derives its destructive force from nuclear reactions, either fission (fission bomb) or from a combination of fission and fusion reactions (thermonuclear bomb). Both bomb types release large quantities of energy from relatively small amounts of matter.
Today, nine states have nuclear weapons and many more can easily acquire those, although only five states are officially recognized as possessing nuclear weapons by the 1968 nuclear Non Proliferation Treaty (NPT). Those are
• The United States (1945)
• Russia (1949)
• The United Kingdom (1952)
• France (1960) and
• China (1964)
Four states never joined the NPT but are known to possess nuclear weapons:
• Israel
• India (1974)
• Pakistan (1998) and
• North Korea (2006)
Dyes are colored organic compounds that are used to impart color to various substrates, including paper, leather, fur, hair, drugs, cosmetics, waxes, greases, plastics and textile materials.

Instrumentation and process control in soap making industryIhsan Wassan
Soap is integral to our society today. For generation its use has increased and its manufacture has become an industry essential to the comfort and health of civilized human beings. Therefore we can say that Soaps and detergents occupy a vital place in modern chemical science.
Boilers are most important part of Chemical Industry. 99 % boilers used in Pakistan Chemical Industries are water tube boilers because of their high efficiency and safety. So we should have clear understanding about the boilers.
Agitation and Mixing are two important unit operations used in industries such as Impellers agitators are widely used to circulate the liquid through the vessel in which the dispersion of liquids and gases into other liquids like mixing of stiff paste, elastomers and dry solids powders takes place.
CFD Simulation of By-pass Flow in a HRSG module by R&R Consult.pptxR&R Consult
CFD analysis is incredibly effective at solving mysteries and improving the performance of complex systems!
Here's a great example: At a large natural gas-fired power plant, where they use waste heat to generate steam and energy, they were puzzled that their boiler wasn't producing as much steam as expected.
R&R and Tetra Engineering Group Inc. were asked to solve the issue with reduced steam production.
An inspection had shown that a significant amount of hot flue gas was bypassing the boiler tubes, where the heat was supposed to be transferred.
R&R Consult conducted a CFD analysis, which revealed that 6.3% of the flue gas was bypassing the boiler tubes without transferring heat. The analysis also showed that the flue gas was instead being directed along the sides of the boiler and between the modules that were supposed to capture the heat. This was the cause of the reduced performance.
Based on our results, Tetra Engineering installed covering plates to reduce the bypass flow. This improved the boiler's performance and increased electricity production.
It is always satisfying when we can help solve complex challenges like this. Do your systems also need a check-up or optimization? Give us a call!
Work done in cooperation with James Malloy and David Moelling from Tetra Engineering.

2. History ofHistory of C++C++
During 1970 Dennis Ritchiecreated
C Programming language to
develop the UNIX operating system
at Bell Labs.
C is a general-purpose, high-level
language.
C was originally first implemented
on the PDP-11 computerin 1972. Dennis RitchieDennis Ritchie
3. History ofHistory of C++C++
C++ Development started in
1979.
During the creation of Ph.D.
thesis, Bjarne Stro ustrup worked
with language called Simula.
Simula is programming
language basically useful for the
simulation work.
Bjarne StroustrupBjarne Stroustrup
4. History ofHistory of C++C++
Simula was first language to support object-oriented
programming language (OOP).
OOP is a formal programming approach that combines
data and associated actions (methods) into logical
structures (objects).
Bjarne Stro ustrup identified that this OOP features can
be included in the so ftware de ve lo pm e nt, however the
Simula language was far too slow for practical use.
5. History ofHistory of C++C++
After that Bjarne Stroustrup started working on the C
language and added more extra OOP features to the
classic C.
He added features in such a fashion that the basic flavor of
C remains unaffected.
6. History ofHistory of C++C++
His language included some add-on features such as
classes,
basic inheritance,
default function arguments, and
Polymorphism
7. History ofHistory of C++C++
CLASSCLASS
a blueprint for a data type.
it does define what the class name means, that is, what
an object of the class will consist of and what operations
can be performed on such an object.
For example, we defined the Box data type using the
keyword class as follows:
8. History ofHistory of C++C++
InheritanceInheritance
Inheritance allows us to define a class in terms of
another class, which makes it easier to create and
maintain an application.
The idea of inheritance implements the is a relationship.
For example, mammal IS-A animal, dog IS-A mammal
hence dog IS-A animal as well and so on.
9. History ofHistory of C++C++
Default function argumentsDefault function arguments
Allows a function to be called without providing one or
more irregular arguments.
10. History ofHistory of C++C++
PolymorphismPolymorphism
The word polymorphism means having many forms.
Typically, polymorphism occurs when there is a
hierarchy of classes and they are related by inheritance.
C++ polymorphism means that a call to a member
function will cause a different function to be executed
depending on the type of object that invokes the
function.
11. History ofHistory of C++C++
Stroustrup states that the purpose of C++ is to make
writing good programs easier and more pleasant for the
individual programmer.
In 1983 the name of the language changed from C with
classes to C++.
12. History ofHistory of C++C++
The ++ operator in the C language is an operator for
incrementing a variable, which gives some insight into
how Stroustrup regarded the language.
Many new features were added around this time, the
most notable of which are virtual functions, function
overloading, references with the & symbol, the constant
keyword, and single-line comments
13. History ofHistory of C++C++
First commercial release of the C++ language was in
October of 1985.
In 1989 C++ language again updated to include
protected and static members .
14. History ofHistory of C++C++
In 1990 the C++ reference manual was released.
Same year turbo C++ was released as a commercial
product.
Turbo C++ added the Plethora of additional libraries.
15. History ofHistory of C++C++
In 1998 the C++ standard committee published the first
internal standard for C++ ISO/IEC14882:1998,
informally known as C++98
In 2003 committee respond to multiple problems
reported with their C++98. Then they change the
language was dubbed C++03
16. History ofHistory of C++C++
In 2005 C++ committee released a report dubbed TR1
detailing various features they were planning to add the
latest C++ standard.
In mid 2011 the new C++ standard C++11 was
published.
