Programming is hard. Programming correct C and C++ is particularly hard. Indeed, both in C and certainly in C++, it is uncommon to see a screenful containing only well defined and conforming code.Why do professional programmers write code like this? Because most programmers do not have a deep understanding of the language they are using.While they sometimes know that certain things are undefined or unspecified, they often do not know why it is so. In these slides we will study small code snippets in C and C++, and use them to discuss the fundamental building blocks, limitations and underlying design philosophies of these wonderful but dangerous programming languages.

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.

Exploiting Artificial Intelligence for Empowering Researchers and Faculty,
International FDP on Fundamentals of Research in Social Sciences
at Integral University, Lucknow, 06.06.2024
By Dr. Vinod Kumar Kanvaria
This presentation was provided by Steph Pollock of The American Psychological Association’s Journals Program, and Damita Snow, of The American Society of Civil Engineers (ASCE), for the initial session of NISO's 2024 Training Series "DEIA in the Scholarly Landscape." Session One: 'Setting Expectations: a DEIA Primer,' was held June 6, 2024.
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

1. Test Program
• #include<conio.h>
• #include <stdio.h>
•
•
•
•
void main()
{
Printf(“Allah is Great“);
}
Copy this code
CSC141 Introduction to Computer
Programming
2. Preprocessing directives
•Performed by a program called the preprocessor
•Modifies the source code (in RAM) according to
preprocessor
directives
(preprocessor
commands) embedded in the source code
•Strips comments and white space from the code.
•The source code as stored on disk is not
modified.
•Examples:
# include, macros #if
CSC141 Introduction to Computer
Programming
3. Compilation
•Performed by a program called the compiler
•Translates the preprocessor-modified source code
into object code (machine code)
•Checks for syntax errors and warnings
•Saves the object code to a disk file, if instructed to
do so.
•If any compiler errors are received, no object code
file will be generated.
•An object code file will be generated if only
warnings, not errors, are received.
CSC141 Introduction to Computer
Programming
4. Object code
•It is machine language code containing various
calls specific to operating system .e.g. the objec
code written by compiler is not only hardware
dependent
but
also
operating
system
dependent.
•So if you have Linux and Windows operating
systems then object file compiled by one
Operating System (OS) will not get executed on
the other OS.
CSC141 Introduction to Computer
Programming
5. Linking
•Combines the program object code with other
object code files to produce the executable file.
•The other object code files can come from the
Run-Time Library, other libraries, or object files
that you have created.
•Saves the executable code to a disk file
•If any linker errors are received, no executable file
will be generated.
CSC141 Introduction to Computer
Programming
6. Program Development
•Editor produces Source File
program.c
•Preprocessor Modified Source Code
not saved on disk
•Compiler produces Object Code File
program.obj
•Linker links Object Code File and Other Object
Code Files (if any) and produces Executable File
program.exe

7. Basic Structure of C programs
#include <stdio.h>
#include <conio.h>
void main ( )
{
printf( “Hello World”);
}
void main ( )
•Every C program consists of one or more functions.
• main ( ) is a function. It is the first function to
which control is passed from OS when a program is
executed
•void indicates that the main function does not
return any value
CSC141 Introduction to Computer
Programming
8. Basic Structure of C programs
#include <stdio.h>
#include <conio.h>
void main ( )
{
Syntax
•printf() is a statement.
•A statement in C is terminated by a semi colon (
;).
printf(“Hello World”);
}
CSC141 Introduction to Computer
Programming
9. Basic Structure of C programs
#include <iostream>
Using namespace std;
void main ( )
{
cout << “Hello World”;
}
Delimiters
•Opening and Closing brace or Curly
brackets marks the start and end of the
code
•The start and end of a block ( such as loop,
if else statement, switch statement) is also
identified by the start and end of curly
brackets.
CSC141 Introduction to Computer
Programming
10. Basic Structure of C programs
Syntax
•C pays no attention to the “whitespace”
characters encountered in a program like
space, carriage return(newline) and tab
•You can put as many whitespaces in your
program as you like; they will be invisible to
the compiler
#include <iostream>
Using namespace std;
void main ( )
{
cout << “Hello World”;
}
CSC141 Introduction to Computer
Programming
11. Basic Structure of C programs
#include <iostream>
Using namespace std;
void main ( )
{
cout << “Hello World”;
}
Indentation
•Stretching the code vertically makes it
more readable
•Indentation of blocks of code enclosed in
braces is an important aspect for making
the programs readable
•e.g. the printf statement that is indented in
the previous example
•The same program below will execute
perfectly
#include <iostream> using namespace std; void main ( ){cout << “Hello World” ;}
CSC141 Introduction to Computer
Programming
12. Variable Names:
Name assigned to a memory location
•Variables are like containers in your computer's memory
•you can store values in them and retrieve or modify them
when necessary.
CSC141 Introduction to Computer
Programming
13. Variable Value:
L-value
•Variables are also known as l-values.
•L-values are values that can be on the left
side of an assignment statement.
•When we do an assignment, the left hand
side of the assignment operator must be an lvalue.
CSC141 Introduction to Computer
Programming
14. R-values (Opposite of L-values)
•An r-value refers to any value that can be
assigned to an l-value.
•R-values are always evaluated to produce a
single value.
Examples
•Single numbers (7, which evaluates to numeric
value 7)
•Variables (x, which evaluates to whatever
number was last assigned to it)
•Expressions (x + 5, which evaluates to the last
value of x plus 5).
CSC141 Introduction to Computer
Programming
16. Variable names are called identifiers
But
all the identifiers are not variable names!!!
Identifiers Refer to the Names of:
•variables
•data types
•Constants
•functions
CSC141 Introduction to Computer
Programming
17. Identifier: Variable Names
Any combination of letters, numbers,
underscore (_)
•Case sensitive
"sum" is different than "Sum“ or “SUM”
and
•Cannot begin with a digit
1stName ------ illegal
devideby10 ---- legal
•Usually, variables beginning with underscore are
used only in special library routines.
_validsystemcall ---- legal
CSC141 Introduction to Computer
Programming
18. Identifier: Variable Names
•Usually only the first 32 characters are significant
aReally_longName_moreThan31chars
aReally_longName_moreThan31characters
(both of the above identifiers are legal and the
same)
•There can be no embedded blanks or special character
gross salary ( is illegal because it contains space )
%rate
( is illegal because it contains special
character )
•Keywords or Reserve words cannot be used as
identifiers
CSC141 Introduction to Computer
float
( is illegal because it contains a
Programming
19. Keywords / Reserved Words
•Some words may not be used as identifiers
•These words have special meaning in C
Keywords
auto
break
case
char
const
continue
default

21. Size and Types of Data Types
•Int
Integer stores an integer value e.g. 125
int (at least 16 bits, commonly 32 bits)
long (at least 32 bits)
short (at least 8 bits)
Signed vs. unsigned integers:
Default is 2’s complement signed integers
Use “unsigned” keyword for unsigned
numbers
CSC141 Introduction to Computer
Programming
22. Size and Types of Data Types
•float floating point (at least 32 bits)
stores decimal value (e.g.
125.1234567)
•double
floating point (commonly 64 bits )
stores decimal value
(e.g. 125.123456789012345)
double the precision of a float
CSC141 Introduction to Computer
Programming
23. Size and Types of Data Types
•char character (at least 8 bits)
stores an integer representing a character
(e.g. ‘A’)
different codes of 8 bit and 15 bit
ANSCII – American National Standard Code
for Information Interchange (8 bits)
EBCDIC – Extended Binary Coded Decimal
interchange Code (8 bits)
UNICODE – 15 bit code
CSC141 Introduction to Computer
Programming
24. Size and Types of Data Types
• void means nothing ( zero bytes)
used for the function return nothing.
e.g. void main ( void)
CSC141 Introduction to Computer
Programming
25. Size of Data Types
Exact size can vary, depending on processor
•int is supposed to be "natural" integer size;
for older processors, it's 16 bits
for most modern processors it’s 32 bits
How can you know the size?
•Use function called sizeof.
e.g. sizeof(int), it returns answer in bytes
CSC141 Introduction to Computer
Programming
26. Additional to Data Type
Like constants but is preprocessor directive
Literal
•Unnamed constants that appear literally in source
code.
Constants
•Variables whose values do not change during the
execution of the program
•This done by appending ‘const” before the data
type
Symbols
•Are values defined by using #define
•Values stay constant during single execution of the
CSC141 Introduction to Computer
Programming
program
28. Constants and Symbol
#define RADIUS 15.0
int main( )
{
const double pi = 3.14159;
double area;
double circum;
area = pi * RADIUS * RADIUS;
circum = 2 * pi * RADIUS;
}
symbol
constant
literal
CSC141 Introduction to Computer
Programming
29. Operators
An operator has:
•Function
What it does?
Example: + , -, *, / or others
•Precedence
In which order it will execute
Example: "a * b + c * d"
will be executed as : "(a * b) + (c * d)"
because multiply (*) has a higher
precedence
than addition (+)
CSC141 Introduction to Computer
Programming
30. Operators
•Associativity
Order In which the operators of the
same precedence combined?
Example: "a - b - c"
will be executed in the order "(a - b) - c"
because add/sub associate left-to-right
CSC141 Introduction to Computer
Programming
31. Assignment Operator
• l-value equals to r-value
x = x + 5;
Evaluate right-hand side (x + 5 ) called r-value
Set l-value ( of left-hand side variable) to r-value.
CSC141 Introduction to Computer
Programming
32. Assignment Operator (contd..)
•All expressions evaluate to a value with the
assignment operator
Example:
y = x = 5;
the result is the value assigned
•Assignment is associated from right to left.
y = x = 5;
y gets the value 5,
because (x = 5) evaluates to the value 5
CSC141 Introduction to Computer
Programming
34. Arithmetic Operators
• Addition, subtraction, and multiplication work as
you would expect.
• Division (/) returns the whole part of the division
(the quotient)
12 / 3 = 4
15 / 2 = 7
• Modulus (%) returns the remainder
12 % 3 = 0
15 % 2 = 1
• Example of precedence
2+3*4
equals
14
where as (2 + 3) * 4 equals
CSC141 Introduction to Computer
Programming
20
35. Arithmetic Expressions
•If mixed types, smaller type is "promoted" to larger
Example: x + 4.3
if x is int, converted to double and result is double
•Integer division -- fraction is dropped
Example: x / 3
if x is int and x=5, result is 1 (not 1.666666...)
• Parentheses ( ) can be used to force a different order of
evaluation:
12 - 5 * 2 = 2
But (12 - 5) * 2 = 14
CSC141 Introduction to Computer
Programming
36. Arithmetic Operator Precedence
•Precedence rules specify the order in which operators are
evaluated
•Associativity determines from Left-to- Right order
•Remember for arithmetic operators precedence
PMDAS
Parentheses, Multiplication, Division, Addition, Subtraction

37. Bitwise Operators
~
<<
>>
bitwise NOT
shift left
shift right
&
^
|
bitwise AND
bitwise XOR
bitwise OR
~x
x << y
x >> y

Example
Association
!
&&
||
Logical NOT !x
logical AND x && y
logical OR
x || y
Right to Left
Right to Left
Right to Left
Treats entire variable (or value) as:
TRUE (non-zero), or FALSE (zero)

40. Assignment ( =) vs. Equality ( ==)
Be Careful using equality (==) and assignment (=)
operators:
int x = 5;
int y = 7;
if (x == y) {
printf(“ will not be printedn”);
}
if (x = y) {
printf(“x = %d y = %d”, x, y);
}
Result: “x = 7 y = 7” is printed.
Explain?

41. Special Operators: ++ and -Increment and decrement the value of variable before or after
its value is used in an expression.
Symbol
++
-++
--
Example
x++
x-++x
--x
Operation
Increment after (Post increment)
decrement after (Post decrement)
Increment before (Pre increment)
decrement before (Pre decrement)
CSC141 Introduction to Computer
Programming
42. Examples Using ++ and -Example-1:
int x = 4;
y = x++;
printf ( “X = %d t “Y = %d “, x, y )
will print
X=5 Y=4
as x is incremented after assignment operation.
Example-2:
x = 4;
y = ++x;
printf ( “X = %d t “Y = %d “, x, y )
will print
X=5 Y=5
as x is incremented before assignment operation.
CSC141 Introduction to Computer
Programming
43. Special Operators: +=, *=, etc.
Arithmetic operators and bitwise operators can be
combined with assignment operator
Equivalent assignment statement:
x += y; Equivalent to
x = x + y;
x -= y;
Equivalent to
x = x - y;
x *= y;
Equivalent to
x = x * y;
x /= y;
Equivalent to
x = x / y;
x %= y; Equivalent to
x = x % y;
x &= y; Equivalent to
x = x & y;
x |= y;
Equivalent to
x = x | y;
x ^= y; Equivalent to
x = x ^ y;
x <<= y; Equivalent to
x = x << y;
x >>= y; Equivalent to
x = x >> y;
