Structure: Initially (in C) a structure was used to bundle different type of data types together to
perform a particular functionality. But C++ extended the structure to contain functions also. The
major difference is that all declarations inside a structure are by default public.

Class: Class is a successor of Structure. By default all the members inside the class are private.

one more difference apart from public and private access specifier, that struct dont have protected as an access specifier while class do.

There are two differences between Structure and Class. Firstly, Structure cannot be inherited. Secondly, Structure is a value data type whereas Class is a reference type.

1) structure instances cannot be used as operand to arithmetic operators like +-*/ . But object (instances of classes) can be (using operator overloading).
2) There is no data hiding features comes with structures. Classes do, private, protected and public

A structure is a convenient tool for handling a logicaly related data items,it is a user defined data type with templet.
Example:
struct student
{
char name[20];
int Roll_no;
float marks;
};
A class is an extention of the idea of stucture used in C.It is a way of creating and implementing a user defined data type
Example:
class class_name
{
private:
variable declaration;
function decleration;
public:
variable declaration;
function decleration;
};
A structure do not hav the property of data hiding that is all the members of structure are accessible by any function anywere in there scope.that is the data member of structure are public by default
A class have the property of data hiding that is the data member of the class are accessible only by there object,the data member of class are private by default

the difference between class and structure are by default all the data members are private but in structure by default it's private.

class:-
class is extracted for the fetures of oops
sturcture
structure the collection of all members of different data types
class:-
in class we can use all the 3 access specifiers and they are
1.private
2.public
3.protected
structure:-
we use only private(defult)
structure:-
structure has a keyword struct
class:-
class itself is an keyword
sturcture:-
structure has more security
class:-
class has a low security when compared to structure
structure:
we use "->" for accessing
class:-
in class we use "."

1.By default the members of a structure are public and for a class they are private.
2.A structure can't declare protected members,a class can.
3.A structure can't be abstract, a class can.
4.A structure is a value type, while a class is a reference type.

Structure:
1. By default, the members of a structure are public i.e structure variables can be accessed by any function (data hiding is not possible)

2. In structure, we can declare only variables.

3. we can't inherit a structue from another structure.

class:
1. By default, the members are private i.e class variables can be accessed by only class member functions. (datahiding is possible)

2. In classes we can declare both data members and member functions.

3. We can inherit a class from another class.
