Operator overloading can transform complex, obscure program listings into intuitively obvious ones. For examples, statements like :
ob3.addobjects ( ob1, ob2) or ob3 = ob1.addobjects( ob2) can be changed to the much more readable like ob3 = ob1 + ob2.
Note : The process of selecting the most appropriate overloaded function or operator is called overload resolution.

The term overloading means ‘providing multiple definitions of’. Overloading of functions involves defining distinct functions which share the same name, each of which has a unique signature. Function overloading is appropriate for:
Defining functions which essentially do the same thing, but operate on different data types.
Providing alternate interfaces to the same function.
Function overloading is purely a programming convenience.
Operators are similar to functions in that they take operands (arguments) and return a value. Most of the built-in C++ operators are already overloaded. For example, the + operator can be used to add two integers, two reals, or two addresses. Therefore, it has multiple definitions. The built-in definitions of the operators are restricted to built-in types. Additional definitions can be provided by the programmer so that they can also operate on user-defined types. Each additional definition is implemented by a function.

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.
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.

● 7.1 Defining operator Overloading
● 7.2 Overloading Unary Operator
● 7.3 Overloading Binary Operator
● 7.4 Overloading Operator Using Friend function
● 7.6 Type Conversion
3. Introduction
● C++ has ability to provide the operators with a special meanings for a data type.
● The mechanism of giving such special meaning to an operator is known as operator overloading.
Why Operator Overloading?
● Readable code
● Make operators sensitive to context
4. General Format for operator overloading
returnType operator operator_symbol(parameters);
➔ Return type may be whatever the operator returns
➔ Including a reference to the object of the operand
➔ Operator symbol may be any overloadable operator from the list.
5. Restrictions on Operator Overloading
● C++ operators that can be overloaded.
● C++ Operators that cannot be overloaded Operators that cannot be overloaded .
6. Overloading Unary Operator
#include <iostream.h>
class temp
{ Output Count: 6
private:
int count;
Public:
temp():count(5) { }
void operator ++()
{ count=count+1;}
void Display()
{ cout<<"Count: "<<count; }
};
int main()
{
temp t;
++t; /* operator function void operator ++() is called */
t.Display();
return 0;
}
7. Note
Operator overloading cannot be used to change the way operator works on built-in types. Operator
overloading only allows to redefine the meaning of operator for user-defined types.
Only existing operators can be overloaded. New operators cannot be created.
The overloaded operator must have at least one operand that is of user-defined type.
We cannot change the basic meaning of an operator.
Overloaded operators follow the syntax rules of the original operators.
10. Overloading operators using Friend
● Friend function using operator overloading offers better flexibility to the class.
● These functions are not a members of the class and they do not have 'this' pointer.
● When you overload a unary operator you have to pass one argument.
● When you overload a binary operator you have to pass two arguments.
● Friend function can access private members of a class directly.
● friend return-type operator operator-symbol (Variable 1, Varibale2)
{
//Statements;
}

{
int a=10;
int b=20;
int c=30;

}
void friend operator-(UnaryFriend &x);
};
void operator-(UnaryFriend &x)
{
x.a = -x.a;
x.b = -x.b;
x.c = -x.c;
}
int main()
{

14. Type Conversions
● the type conversions are automatic only when the data types involved are built-in types.
● int m; float x = 3.14159; m = x;// convert x to integer before its value is assigned // to m.
● For user defined data types, the compiler does not support automatic type conversions.
● Different situations of data conversion between incompatible types.
● Conversion from basic type to class type.
● Conversion from class type to basic type.
● Conversion from one class type to another class type.
15. Basic to Class Type
A constructor to build a string type object from a char * type variable.
string : : string(char *a)
{
length = strlen(a);
P = new char[length+1];
strcpy(P,a);
}
The variables length and p are data members of the class string.
16. Class To Basic Type
● A constructor function do not support type conversion from a class type to a basic type.
● An overloaded casting operator is used to convert a class type data to a basic type. It is also
referred to as conversion function.
● operator typename( )
{ … ( function statements ) … }
● This function converts a class type data to typename.
vector : : operator double( )
{
double sum = 0;
for (int i=0; i < size ; i++)
sum = sum + v[i] * v[i];
return sqrt (sum);
}
● This function converts a vector to the square root of the sum of squares of its components.
17. Continue...
The casting operator function should satisfy the following conditions:
● It must be a class member.
● It must not specify a return type.
● It must not have any arguments.
18. One Class To Another Class Type
● Type objX = objY ; // objects of different types objX is an object of class X and objY is an object of
class Y.
● The class Y type data is converted to the class X type data and the converted value is assigned to
the objX.
● Conversion is takes place from class Y to class X.
● Y is known as source class.
● X is known as destination class.
