C was originally developed in the 1970s by Dennis Ritchie at Bell Labs. It is a high-level, general-purpose programming language that contains features allowing it to be used for both system and application programming. The C language consists of characters, numbers, and symbols that form tokens like identifiers, keywords, constants, operators, and punctuation. Variables, functions, and other elements in C are given unique identifiers to represent storage areas that can be manipulated. Constants are values that cannot be altered, and different types of constants like integers, floats, characters, and strings are used. Operators perform arithmetic, relational, logical, and other operations on values and variables in C programs.

Immunizing Image Classifiers Against Localized Adversary Attacksgerogepatton
This paper addresses the vulnerability of deep learning models, particularly convolutional neural networks
(CNN)s, to adversarial attacks and presents a proactive training technique designed to counter them. We
introduce a novel volumization algorithm, which transforms 2D images into 3D volumetric representations.
When combined with 3D convolution and deep curriculum learning optimization (CLO), itsignificantly improves
the immunity of models against localized universal attacks by up to 40%. We evaluate our proposed approach
using contemporary CNN architectures and the modified Canadian Institute for Advanced Research (CIFAR-10
and CIFAR-100) and ImageNet Large Scale Visual Recognition Challenge (ILSVRC12) datasets, showcasing
accuracy improvements over previous techniques. The results indicate that the combination of the volumetric
input and curriculum learning holds significant promise for mitigating adversarial attacks without necessitating
adversary training.

Courier management system project report.pdfKamal Acharya
It is now-a-days very important for the people to send or receive articles like imported furniture, electronic items, gifts, business goods and the like. People depend vastly on different transport systems which mostly use the manual way of receiving and delivering the articles. There is no way to track the articles till they are received and there is no way to let the customer know what happened in transit, once he booked some articles. In such a situation, we need a system which completely computerizes the cargo activities including time to time tracking of the articles sent. This need is fulfilled by Courier Management System software which is online software for the cargo management people that enables them to receive the goods from a source and send them to a required destination and track their status from time to time.
Cosmetic shop management system project report.pdfKamal Acharya
Buying new cosmetic products is difficult. It can even be scary for those who have sensitive skin and are prone to skin trouble. The information needed to alleviate this problem is on the back of each product, but it's thought to interpret those ingredient lists unless you have a background in chemistry.
Instead of buying and hoping for the best, we can use data science to help us predict which products may be good fits for us. It includes various function programs to do the above mentioned tasks.
Data file handling has been effectively used in the program.
The automated cosmetic shop management system should deal with the automation of general workflow and administration process of the shop. The main processes of the system focus on customer's request where the system is able to search the most appropriate products and deliver it to the customers. It should help the employees to quickly identify the list of cosmetic product that have reached the minimum quantity and also keep a track of expired date for each cosmetic product. It should help the employees to find the rack number in which the product is placed.It is also Faster and more efficient way.

1. Basics of ‘C’
By Gaikwad Varsha P.
Asst. Prof. Information Technology Dept.
Govt. College of Engg. Aurangabad
2. General Aspect of ‘C’
C was originally developed in the 1970s, by Dennis Ritchie
at Bell Telephone Laboratories, Inc.
C is a High level , general –purpose structured
programming language. Instructions of C consists of terms
that are very closely same to algebraic expressions,
consisting of certain English keywords such as if, else,
for ,do and while
C contains certain additional features that allows it to be
used at a lower level , acting as bridge between machine
language and the high level languages.
This allows C to be used for system programming as well
as for applications programming
3. The Character set of ‘C’
C language consist of some characters set, numbers and
some special symbols. The character set of C consist of all
the alphabets of English language. C consist of
Alphabets a to z, A to Z
Numeric 0,1 to 9
Special Symbols {,},[,],?,+,-,*,/,%,!,;,and more
The words formed from the character set are building
blocks of C and are sometimes known as tokens. These
tokens represent the individual entity of language. The
following different types of token are used in C
1) Identifiers 2)Keywords 3)Constants
4) Operators 5)Punctuation Symbols
4. Identifiers
• A 'C' program consist of two types of elements , user
defined and system defined. Idetifiers is nothing but a
name given to these eleme
• nts.
• An identifier is a word used by a programmer to name a
variable , function, or label.
• identifiers consist of letters and digits, in any order,
except that the first charecter or lable.
• Identifiers consist of letters and digits if any order,except
that the first charecter must be letter.
• Both Upper and lowercase letters can be used
5. Keywords
• Keywords are nothing but
system defined identifiers.
• Keywords are reserved
words of the language.
• They have specific meaning
in the language and cannot
be used by the programmer
as variable or constant
names
• C is case senitive, it means
these must be used as it is
• 32 Keywords in C
Programming
auto double int struct
break else long switch
case enum register typedef
char extern return union
const float short unsigned
continue for signed void
default goto sizeof volatile
do if static while
6. Variables
• A variable is nothing but a name given to a storage area that our programs
can manipulate. Each variable in C has a specific type, which determines
the size and layout of the variable's memory; the range of values that can
be stored within that memory; and the set of operations that can be applied
to the variable.
• The name of a variable can be composed of letters, digits, and the
underscore character. It must begin with either a letter or an underscore.
Upper and lowercase letters are distinct because C is case-sensitive. There
are following basic variable types −
Type Description
• char Typically a single octet(one byte). This is an integer type.
• int The most natural size of integer for the machine.
• float A single-precision floating point value.
• double A double-precision floating point value.
• void Represents the absence of type.
7. Constants
• A constant is a value or an identifier whose value cannot be
altered in a program. For example: 1, 2.5,
• As mentioned, an identifier also can be defined as a constant.
eg. const double PI = 3.14
• Here, PI is a constant. Basically what it means is that, PI and
3.14 is same for this program.
Integer constants
• A integer constant is a numeric constant (associated with
number) without any fractional or exponential part. There are
three types of integer constants in C programming:
• decimal constant(base 10)
• octal constant(base 8)
• hexadecimal constant(base 16)
8. Constants
Floating-point constants
• A floating point constant is a numeric constant that has
either a fractional form or an exponent form. For
example: 2.0,0.0000234,-0.22E-5
Character constants
• A character constant is a constant which uses single
quotation around characters. For example: 'a', 'l', 'm', 'F'
String constants
• String constants are the constants which are enclosed in
a pair of double-quote marks. For example: "good"
,"x","Earth is roundn"
9. Escape Sequences
Sometimes, it is necessary to use characters which cannot be typed or has
special meaning in C programming. For example: newline(enter), tab,
question mark etc. In order to use these characters, escape sequence is
used.
• For example: n is used for newline. The backslash ( ) causes "escape"
from the normal way the characters are interpreted by the compiler.Escape
Sequences Character
• b Backspace
• f Form feed
• n Newline
• r Return
• t Horizontal tab
• v Vertical tab
• Backslash
• ' Single quotation mark
• " Double quotation mark
• ? Question mark
• 0 Null character
10. Operators in C:An operator is a symbol which operates on a
value or a variable. For example: + is an operator to perform addition.
C programming has wide range of operators to perform
various operations. For better understanding of
operators, these operators can be classified as:
• Arithmetic Operators
• Increment and Decrement Operators
• Assignment Operators
• Relational Operators
• Logical Operators
• Conditional Operators
• Bitwise Operators
• Special Operators
11. Arithmetic Operator
• Operator Meaning of Operator
• + addition or unary plus
• - subtraction or unary minus
• * multiplication
• / division
• % remainder after
division( modulo division)
12. Increment and Decrement Operators
1. C programming has two operators increment
++ and decrement -- to change the value of an
operand (constant or variable) by 1.
2. Increment ++ increases the value by 1
whereas decrement -- decreases the value by 1.
3. These two operators are unary operators,
meaning they only operate on a single operand.
eg. int a=10, b=100
++a = 11
--b = 99
13. C Assignment Operators
• An assignment operator is used for assigning a
value to a variable. The most common
assignment operator is =
• Operator Example Same as
• = a = b a = b
• += a += b a = a+b
• -= a -= b a = a-b
• *= a *= b a = a*b
• /= a /= b a = a/b
• %= a %= b a = a%b
14. C Relational Operators
• A relational operator checks the relationship between
two operands. If the relation is true, it returns 1; if the
relation is false, it returns value 0.
• Relational operators are used in decision making and
loops.
Operator Meaning of Operator Example
• == Equal to 5 == 3 returns 0
• > Greater than 5 > 3 returns 1
• < Less than 5 < 3 returns 0
• != Not equal to 5 != 3 returns 1
• >= Greater than or equal to 5 >= 3 returns 1
• <= Less than or equal to 5 <= 3 return 0
