1. The document discusses various concepts related to functions in C++ such as function prototypes, passing arguments by reference, default arguments, inline functions, function overloading, and friend functions.
2. It provides examples to explain concepts like passing arguments by reference allows altering the original variable values, a friend function can access private members of a class, and function overloading allows using the same function name for different tasks based on the argument types.
3. The key benefits of concepts like inline functions, passing by reference, and function overloading are also summarized.

A function is a block of code which only runs when it is called. You can pass data, known as parameters, into a function. Functions are used to perform certain actions, and they are important for reusing code: Define the code once, and use it many times.
A function is a group of statements that together perform a task. Every C program has at least one function, which is main(), and all the most trivial programs can define additional functions. You can divide up your code into separate functions.

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 Roman Empire A Historical Colossus.pdfkaushalkr1407
The Roman Empire, a vast and enduring power, stands as one of history's most remarkable civilizations, leaving an indelible imprint on the world. It emerged from the Roman Republic, transitioning into an imperial powerhouse under the leadership of Augustus Caesar in 27 BCE. This transformation marked the beginning of an era defined by unprecedented territorial expansion, architectural marvels, and profound cultural influence.
The empire's roots lie in the city of Rome, founded, according to legend, by Romulus in 753 BCE. Over centuries, Rome evolved from a small settlement to a formidable republic, characterized by a complex political system with elected officials and checks on power. However, internal strife, class conflicts, and military ambitions paved the way for the end of the Republic. Julius Caesar’s dictatorship and subsequent assassination in 44 BCE created a power vacuum, leading to a civil war. Octavian, later Augustus, emerged victorious, heralding the Roman Empire’s birth.
Under Augustus, the empire experienced the Pax Romana, a 200-year period of relative peace and stability. Augustus reformed the military, established efficient administrative systems, and initiated grand construction projects. The empire's borders expanded, encompassing territories from Britain to Egypt and from Spain to the Euphrates. Roman legions, renowned for their discipline and engineering prowess, secured and maintained these vast territories, building roads, fortifications, and cities that facilitated control and integration.
The Roman Empire’s society was hierarchical, with a rigid class system. At the top were the patricians, wealthy elites who held significant political power. Below them were the plebeians, free citizens with limited political influence, and the vast numbers of slaves who formed the backbone of the economy. The family unit was central, governed by the paterfamilias, the male head who held absolute authority.
Culturally, the Romans were eclectic, absorbing and adapting elements from the civilizations they encountered, particularly the Greeks. Roman art, literature, and philosophy reflected this synthesis, creating a rich cultural tapestry. Latin, the Roman language, became the lingua franca of the Western world, influencing numerous modern languages.
Roman architecture and engineering achievements were monumental. They perfected the arch, vault, and dome, constructing enduring structures like the Colosseum, Pantheon, and aqueducts. These engineering marvels not only showcased Roman ingenuity but also served practical purposes, from public entertainment to water supply.

June 3, 2024 Anti-Semitism Letter Sent to MIT President Kornbluth and MIT Cor...Levi Shapiro
Letter from the Congress of the United States regarding Anti-Semitism sent June 3rd to MIT President Sally Kornbluth, MIT Corp Chair, Mark Gorenberg
Dear Dr. Kornbluth and Mr. Gorenberg,
The US House of Representatives is deeply concerned by ongoing and pervasive acts of antisemitic
harassment and intimidation at the Massachusetts Institute of Technology (MIT). Failing to act decisively to ensure a safe learning environment for all students would be a grave dereliction of your responsibilities as President of MIT and Chair of the MIT Corporation.
This Congress will not stand idly by and allow an environment hostile to Jewish students to persist. The House believes that your institution is in violation of Title VI of the Civil Rights Act, and the inability or
unwillingness to rectify this violation through action requires accountability.
Postsecondary education is a unique opportunity for students to learn and have their ideas and beliefs challenged. However, universities receiving hundreds of millions of federal funds annually have denied
students that opportunity and have been hijacked to become venues for the promotion of terrorism, antisemitic harassment and intimidation, unlawful encampments, and in some cases, assaults and riots.
The House of Representatives will not countenance the use of federal funds to indoctrinate students into hateful, antisemitic, anti-American supporters of terrorism. Investigations into campus antisemitism by the Committee on Education and the Workforce and the Committee on Ways and Means have been expanded into a Congress-wide probe across all relevant jurisdictions to address this national crisis. The undersigned Committees will conduct oversight into the use of federal funds at MIT and its learning environment under authorities granted to each Committee.
• The Committee on Education and the Workforce has been investigating your institution since December 7, 2023. The Committee has broad jurisdiction over postsecondary education, including its compliance with Title VI of the Civil Rights Act, campus safety concerns over disruptions to the learning environment, and the awarding of federal student aid under the Higher Education Act.
• The Committee on Oversight and Accountability is investigating the sources of funding and other support flowing to groups espousing pro-Hamas propaganda and engaged in antisemitic harassment and intimidation of students. The Committee on Oversight and Accountability is the principal oversight committee of the US House of Representatives and has broad authority to investigate “any matter” at “any time” under House Rule X.
• The Committee on Ways and Means has been investigating several universities since November 15, 2023, when the Committee held a hearing entitled From Ivory Towers to Dark Corners: Investigating the Nexus Between Antisemitism, Tax-Exempt Universities, and Terror Financing. The Committee followed the hearing with letters to those institutions on January 10, 202
2024.06.01 Introducing a competency framework for languag learning materials ...Sandy Millin
http://sandymillin.wordpress.com/iateflwebinar2024
Published classroom materials form the basis of syllabuses, drive teacher professional development, and have a potentially huge influence on learners, teachers and education systems. All teachers also create their own materials, whether a few sentences on a blackboard, a highly-structured fully-realised online course, or anything in between. Despite this, the knowledge and skills needed to create effective language learning materials are rarely part of teacher training, and are mostly learnt by trial and error.
Knowledge and skills frameworks, generally called competency frameworks, for ELT teachers, trainers and managers have existed for a few years now. However, until I created one for my MA dissertation, there wasn’t one drawing together what we need to know and do to be able to effectively produce language learning materials.
This webinar will introduce you to my framework, highlighting the key competencies I identified from my research. It will also show how anybody involved in language teaching (any language, not just English!), teacher training, managing schools or developing language learning materials can benefit from using the framework.
2. Main Function
Function prototyping
Call by reference
Return by referenceReturn by reference
Inline functions
Default arguments
Const arguments
Function overloading
Friend functions and class
3. What is the difference between main
function in C and C++?
C does not specify the return type for theC does not specify the return type for the
main() whereas in C++ the main() returns a
value of type int.
4. The prototype describes the function interface to the
compiler by giving details such as the number and
type of arguments and the type of return values.
A template is used when declaring and defining aA template is used when declaring and defining a
function.
Syntax:
type function_name (argument_list);
Eg:
float volume ( int x, float y, float z)
5. Check whether the following function prototype
is correct or not. Give reasons.
1. float volume (int x, float y, z)
2. float volume (int, float, float)2. float volume (int, float, float)
Incorrect
Each argument variable must be declared
independently.
Correct
Variable names are optional.
6. C++ permits to pass parameters to the
functions by reference.
When we pass arguments by reference, the
formal arguments in the called function
become aliases to the actual arguments in
the calling function.
It is used where we would like to alter the
values of variables in the calling function.
7. Example:
void swap (int &a, int &b)
{
int t = a;int t = a;
a = b;
b = t;
}
Function call swap(m, n)
Values of m and n are exchanged using their
aliases a and b.
8. A function can also return a reference.
Example:
int & max (int & x, int & y)
{
if ( x > y )if ( x > y )
return x;
else
return y;
}
Since the return type of max() is int & the
function will return reference to x or y and not
the values.
9. An inline function is a function that is expanded
in line when it is invoked.
Syntax:
inline function-header
{{
function body
}
Eg:
inline double cube(double a)
{
return (a*a*a);
}
10. The above inline function is invoked as:
c = cube(3.0);
The speed benefits of inline functionThe speed benefits of inline function
diminish as the function grows in size.
Example
11. C++ allows to call a function without specifying
all its arguments.
For eg:
float amount ( float principal, int period, float
rate=0.15)
A function call:
value = amount (5000, 7); // one argument missing
value = amount ( 5000, 5, 0.12) // all arguments
12. In C++ an argument to a function can be
declared as const
Eg:
int strlen ( const char *p );
int length ( const string &s);
The qualifier const tells the compiler that
the function should not modify the
argument.
13. Function overloading means to use same
function name to create functions that
perform variety of different tasks.
The function would perform differentThe function would perform different
operations depending on the argument list in
the function call.
The correct function to be invoked is
determined by checking the number and type
of the arguments but not on the function
type.
15. A function call first matches the prototype having the same
number and type of arguments and then call the appropriate
function for execution.
If an exact match is not found, the compiler uses the integral
promotions to the actual arguments such as char to int, float
to double.
If either of them fails, the compiler tries to use the built in
conversations to the actual arguments and then uses the
functions whose match is unique.
long square(long n)
double square(double x)
A function call square(10) will cause an error because int
argument can be converted into either long or double there by
causing ambiguous situation.
16. Function overloading is used when we want
functions to perform closely related tasks.
Sometimes default arguments may be usedSometimes default arguments may be used
instead of overloading.
Example
17. C++ allows the common functions to be made
friendly to the classes.
For eg: consider two classes manager and
scientists and they want to use a function
income_tax().
So we make this function friendly with both the
classes, thereby allowing the function to have
access to the private data of these classes.
19. A Friend function possesses certain special
characteristics:
It is not in the scope of the class to which it has been
declared as friend.
It cannot be called using the object of the class.(as it
doesn’t come under the scope of the class)
It can be invoked like a normal function without theIt can be invoked like a normal function without the
help of any object.
Unlike member functions, it cannot access the
member names directly and has to use an object
name and dot membership operator with each
member name.
It can be declared either in public or private part of
the class without affecting its meaning.
Usually, it has the objects as arguments.
20. Class sample
{
int a;
int b;
public:
void setvalue() { a = 25; b = 40; }
friend float mean(sample s);
};
float mean(sample s)
{
return float(s.a + s.b)/2.0;
}
int main()
{
Sample X; //Object X
X.setValue();
cout << “Mean value = “ << mean(X) << “n”;
return 0;
}
21. Member functions of one class can be friend
functions of another class.
class X
{
……
…………
int fun1(); // member function of X
……
};
class Y
{
……
……
friend int X :: fun1(); // fun1() of X is friend of Y
……
};
22. class ABC; // forward declaration
class XYZ
{
int x;
public:
void setvalue(int i ) { x = i ; }void setvalue(int i ) { x = i ; }
friend void max(XYZ, ABC);
};
class ABC
{
int a;
public:
void setvalue(int i ) { a = i; }
friend void max(XYZ, ABC);
};
23. void max(XYZ m, ABC n ) // definition of friend
{
if ( m.x >= n.a)
cout << m.x;
else
cout << n.a;
}}
int main()
{
ABC abc;
abc.setvalue(10);
XYZ xyz;
xyz.setvalue(20);
max(xyz, abc);
return 0;
}
24. A friend function can access and alter the values
of private members of the class, thus violating
the data hiding principle of OOPs.
This can be done by calling friend function byThis can be done by calling friend function by
reference.
Here the local copies of the objects are not
made instead a pointer to the address of the
object is passed and the called function directly
works on the actual object used in the call.
25. class class_2;
class class_1
{
int value1;
public:
void indata(int a) { value1 = a; }
void display() { cout<< value1 << “n”; }void display() { cout<< value1 << “n”; }
friend void exchange(class_1 &, class_2 &);
};
class class_2
{
int value2;
public:
void indata(int a) { value2 = a; }
void display() { cout<< value2 << “n”; }
friend void exchange(class_1 &, class_2 &);
};
26. void exchange(class_1 & x, class_2 & y) // object x and y are aliases
{ of C1 and C2
int temp = x.value1; // directly modifying the values of
x.value1 = y.value2; value1 and value2 of class_1 and
y.value2 = temp; class_2
}
int main()
{
class_1 c1;
class_2 c2;
c1.indata(100);c1.indata(100);
c2.indata(200);
cout << “values before exchange” << “n”;
c1.display();
c2.dispaly();
exchange( c1, c2);
cout << “values after exchange” << “n”;
c1.display();
c2.dispaly();
return 0;
}
27. We can declare all the member functions of
a class as a friend function of another class.
In such cases the class is known as a friend
class.
Syntax:Syntax:
class Z
{
……….
friend class X;
};
28. State true or false:
Class members are public by default.
Friend functions have access to only public members
of class.
An entire class can be made a friend of another class.
Functions cannot return class objects.
A function designed as private is accessible only to
member functions of that class.
A function designed as public can be accessed like any
other ordinary functions.
29. When will you make a function inline? Why?
When a function is small and is likely to be called many time we make it
as inline. Inline expansion makes a program run faster because the
overhead of a function call and return is eliminated.
How does an inline function differ from a pre-processor macro?
The compiler replaces the function code when the inline functions areThe compiler replaces the function code when the inline functions are
called and hence perform type checking whereas macro are simply the
substitution of code by the pre-processor before compilation and hence
no type checking or error checking.
What is the significance of an empty parenthesis in a function
declaration?
Empty parenthesis indicates that the function does not contains any
arguments.
30. What is the main advantages of passing arguments by
reference?
When the arguments are passed by reference then we can
alter the original data instead of its local copies.
What do you meant by overloading of a function? When doWhat do you meant by overloading of a function? When do
we use this concept?
Function overloading means to use same function name to
create functions that perform variety of different tasks.
Function overloading is used perform different operations
depending on the argument list in the function call. It is also
used for handling class objects.
