Structures are collections of variables of different data types, while classes can also contain functions. The main differences are: structures have public access by default, are used for small data groups, and objects are stored on the stack. Classes have private access by default, are used for larger amounts of data with abstraction and inheritance, and objects are stored on the heap. Both allow variables, functions, constructors/destructors, and inheritance, but classes provide more robust features for object-oriented programming.

5. Structure is a user defined data type which is a collection of simple variables
these variables can be of different types such as int,float,char and so on the
difference between structure and array is in this point that array is also the
collection of simple data types but array is the collection of the same data
types and struct is the collection of different kinds of data types.
 each structure must be defined first after that we can create it’s objects in
another functions such as in main().

8. C structure
 Only variable of different data types can be created functions are not allowed.
 Use of ‘struct’ keyword is necessary while declaring the objects of the structure.
 Member variables cannot be initialized inside the structure.
 We can’t use the static members in c structures .
 Only pointer can be used as the part of the C structure reference is not allowed.
 The compiler gives the size 0 to an empty structure and in C.
 C doesn't allow data hiding in structure.
 C structures don’t know the access modifiers.

9. C++ structure
 We can use both member variables and member functions in C++.
 C++ also have .* and -> operators to access individual members of struct, but C
doesn't have such kind of operators.
 The compiler gives the size 1 to an empty structure in C++.
 C++ allows the concept of data hiding in structure.
 C++ structure have access modifiers as these are included in the structure of this
language.
 We can use static members inside a C++ structure.
 We can initialize a structure members inside the structure even the C++11 thanks to
the ones who do this work.

10. Class is also a user defined data type which can
have deferent types of data types and member
functions inside it’s body.
 class is the same as structure but has some
differences with it we will talk about it.
We use the keyword Class for the declaration of the
class.

13. THE SIMILARITIES BETWEEN STRUCT AND CLASS
You can declare member variable in both.
You can create member functions in both.
You can create objects from both class and structure.
You can create constructor and destructors in both class and
structure.
Inheritance is possible in both class and structure.
You can inherit a structure from a class and do the reverse.
You can use access specifiers In both class and structure.

14. THE DIFFERENCES BETWEEN CLASS AND
STRUCTURE

15. Structure:
Key word for the declaration is struct.
Default access specifiers is public.
Purpose :Generally grouping of data.
Usage : generally used for small amount of data.
Type: value.
Storage: object is created on the stack memory.
It can have only parameterized constructors and destructors.

16. Class :
Key word for the declaration is class.
Default access specifiers is private.
Purpose: data abstraction and further inheritance.
Usage: generally used for large amount of data.
Type: reference .
Storage : object is created on the heap memory.
It can have all types of constructors and destructors.

17. Class :
In class inheritance the default access specifiers is private.
But
In structure inheritance the default access specifiers is
public.
