This document provides an overview of C++ and object-oriented programming concepts. It discusses:
1. C++ is an object-oriented programming language introduced in the 1980s that retains the power of C and adds classes, inheritance, function overloading, and operator overloading.
2. OOP languages like C++ are well-suited for developing large, complex programs like editors, compilers, databases, and communication systems due to features like modularity and code reusability.
3. A simple C++ program is presented that demonstrates basic syntax like main(), comments, cout and << operators, and return type for main(). Classes and member functions are also introduced.

We write programs to solve our problem and get our work done. Object Oriented Programming is basically considered as design methodology for creating a non-rigid application. In OOPS every logic is written to get our work done, but this is done based on entity which we call it as Objects. OOP allow us to decompose our problem in to small unit of work which are accessed via Objects. We build function around this objects. There are mainly four pillars (features) of OOP.

A C++ program //include headers; these are modules that include functions that you may use in your //program; we will almost always need to include the header that // defines cin and cout; the header is called iostream.h #include <iostream.h>
int main() {
//variable declaration //read values input from user //computation and print output to user return 0; }
After you write a C++ program you compile it; that is, you run a program called compiler that checks whether the program follows the C++ syntax – if it finds errors, it lists them – If there are no errors, it translates the C++ program into a program in machine language which you can execute.

1. Introduction to C++ and brief historyAhmad177077
C++ is a powerful, high-level programming language that was developed by Bjarne Stroustrup in 1983. It's an extension of the C programming language with added features such as object-oriented programming (OOP) and generic programming capabilities.
Here are some key concepts and features of C++:
Object-Oriented Programming (OOP): C++ supports OOP principles such as classes, objects, inheritance, polymorphism, and encapsulation. This allows for the creation of modular and reusable code.
Syntax: C++ syntax is similar to C, but with additional features. It uses semicolons to end statements and curly braces to define blocks of code. It also supports a wide range of operators for arithmetic, logical, and bitwise operations.
Standard Template Library (STL): C++ provides a rich set of libraries known as the Standard Template Library (STL), which includes containers (like vectors, lists, maps), algorithms (such as sorting and searching), and iterators.
Memory Management: Unlike some higher-level languages, C++ gives programmers control over memory management. It allows manual memory allocation and deallocation using new and delete operators. However, this also introduces the risk of memory leaks and segmentation faults if not used carefully.
Portability: C++ code can be compiled to run on various platforms, making it a portable language. However, platform-specific code may need adjustments for different environments.
Performance: C++ is known for its high performance and efficiency. It allows low-level manipulation of resources, making it suitable for system-level programming, game development, and other performance-critical applications.
Community and Resources: C++ has a vast community of developers and extensive documentation available online. There are many tutorials, forums, and books to help programmers learn and master the language.
When learning C++, it's essential to understand the fundamentals thoroughly, including data types, control structures (like loops and conditionals), functions, and pointers. As you become more proficient, you can explore advanced topics like templates, exception handling, multithreading, and more.
Overall, C++ is a versatile language with a wide range of applications, from system programming to game development to web applications. Mastering it can open up many opportunities for software development.Community and Resources: C++ has a vast community of developers and extensive documentation available online.

A Strategic Approach: GenAI in EducationPeter Windle
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.

The French Revolution, which began in 1789, was a period of radical social and political upheaval in France. It marked the decline of absolute monarchies, the rise of secular and democratic republics, and the eventual rise of Napoleon Bonaparte. This revolutionary period is crucial in understanding the transition from feudalism to modernity in Europe.

2. 2.1 What is C++
• Its an OOP Language
• Introduced by AT&T bell laboratory in 1980’s
• Still retains the power of C
• Initially it was named as “C with classes”
• C++ is a superset of C
• Some differences will prevent the C to run in
the C++ compiler
DMSI 2
3. 2.1 What is C++
• Important features added over C are classes,
inheritance, function overloading and
operator overloading.
• C++ allows programmers to build large
programs with clarity, extensibility, and ease
of maintenance incorporating the spirit and
efficiency of C
• It facilitates(সহজসাধ্য করে ত ালা) bottom up
approach which was top down in case of C
DMSI 3
4. Applications of OOP
• OOP language like C++ or JAVA is capable of
handling large programs easily
• Task includes development of editors,
compilers, databases, communication systems
and any complex real time systems
DMSI 4
5. Applications of OOP
• Since C++ allows us to create hierarchy-related
objects, we can build special object oriented
libraries which can be used later by many
programmers.
• While C++ is able to map the real-world problem
properly, the C part of C++ gives the language the
ability to get close to the machine-level details.
• C++ programs are easily maintainable and
expandable. When a new feature needs to be
implemented, it is vary easy to add to the exiting
structure of an object.
DMSI 5
6. 2.3 A Simple C++ Program
• Printing a string
# include <iostream> // include header file
using namespace std;
Int main()
{
Cout<< “my name is ………..”; //C++ statement
Return 0;
} // end of example
• Program Features
– only one function, main(). //can have more
– Like C the C++ statements terminate with semicolons
DMSI 6
7. Example (cont.)
• Comments
– C++ introduces a new comment symbol //
– Note that there is no closing symbol
• for*(j=0; j<n; /* loops n times */ J++)
– Can we use double slash?
• Output Operator:
• two ne C++ features, cout and <<.
• The operator << is called the insertion or put to
operator
DMSI 7
8. Output Operator:
• You may recall that the operator << is the bit-wise left-
shift operator and it can still be used for this purpose.
• This is an example of how one operator can be used for
different purposes, depending on the context.
• This concept is known an operator overloading, an
important aspect of polymorphism.
DMSI 8
9. The iostream File
• We have used the following #include directive in
the program;
– # include <iostream>
• This directive causes the preprocessor to add the
contents of the iostream file to the program.
• It contains declarations for the identifier cout and
the operator «.
• Some old versions of C++ use a header file called
ioslream.h.
• This is one of the changes introduced by ANSI
C++.
DMSI 9
10. Return Type of main ( )
• In C++, main() returns an integer type value to the operating
system.
• Therefore, every main() in C + + should end with a return(O)
statement; otherwise a warning or an error might occur.
• Since main() returns an integer type value, return type for main() is
explicitly specified as int. Note that the default return type for all
functions in C++ is int.
• The following main without type and return will run with a warning:
• main()
{
-----
-----
}
DMSI 10
11. More C+ + Statements
#include<iostream>
using namespace std;
int main()
{
float v1,v2,sum, average;
cout<< "entr the numversn";
cin>> v1;
cin>> v2;
sum=v1+v2;
average=sum/2;
cout<< "sum= "<<sum<<"n";
cout<< "average= "<<average<<"n";
return 0;
}
DMSI 11
12. • Variables?
• Input Operator?
• Cascading of I/O Operators?
– cout<< "sum= "<<sum<<"n";
– The multiple use of << in one statement is called
cascading
• What is the difference,
cout<< "sum= "<<sum<<“,"
<< "average= "<<average<<"n";
DMSI 12
13. Class
#include <iostream>
using namespace std;
class person
{
char name[30];
int age;
public:
void getdata(void);
void display(void);
};
void person:: getdata(void)
{
cout<<"enter the namen";
cin>> name;
cout<<"enter the agen";
cin>>age;
}
void person:: display(void)
{
cout<<"Name of the person:
"<<name<<"n";
cout<<"Age of the person:
"<<age<<"n";
}
int main()
{
person p;
p.getdata();
p.display();
return 0;
}
14. Class (cont.)
• Class person has two two functions called
member function.
• The main program uses person to declare
variables of its type.
• Here P is an object of type person.
15. Classes in Java:
public class Dog
{
String breed;
int age;
String color;
void barking(){ }
void hungry(){ }
void sleeping(){ }
}
16. Structure of C++ program
• The previous OOP code shows that a typical
code can have four sections….
– Include files
– Class declaration
– Member functions definition
– Main function program
17. Client-Server model
• The class definition includinf the member
functions are known as server and
• The main function is know as client
18. Creating source file
• In C++ we can use text editor to create it
• In UNIX we can use vi or ed editor
• In dos we can use edlin
• The created file should have appropritae
extension to be recognised.
19. Compiling and Linking
• The process of compiling and linking again
depends upon the operating system.
• Each system has its own command to run.
