Object Oriented programming is a superset of structured programming.  Structured programming is as follows:

--Program start
var
var
var

function { ... }
function { ... }
function { ... }

main { ... }
--- Program End

You have units of code, which operate on variables, and are called in reference to those variables, to follow a structure acting on those variables.

Object oriented is as follows:

--- Program Start
object {
var
var
function { ... }
function { ... }
function { ... }
}

var
var

function { ... }
main { ... }
--- Program end

Variables can be objects, which have their own data and functions.  Think like C and structures, except structures can have functions "in them" which operate specificly on their own data.  Thus, instead of referencing a function (a block of code) and telling it to operate on a variableq you reference an object and tell it to perform an operation, most often on itself, specific to itself, using its own data.  Instead of creating units of data to pass to functions which operate on them, you create objects and have them perform operations [on themselves].

Functions attatched to objects don't need a specific name; rather than task_struct_sort_children(task) and acl_rules_struct_sort_children(task), you can have task and acl_rules with task->sort_children() and acl_rules->sort_children(), which have completely different specific function but the same logical function, and operate on the specific instance of the object.

Structured Programming:- we can declare only the member

Object Oriented has attributes and functionality but Structures has only attributes.
