2.  In Pop Top down approach is use in program design.
 In oop bottom up approach use in program design.
 To add new data and function in pop is not so easy.
example:C requires all the variables to be defined at the starting of a scope.
 Oop provide easy way to add new data and function. we can add data member anywhere in program
example:C++ allows the declaration of variable anywhere in the scope i.e. at time of its First use.

3.  In pop No access specifiers are used.
example: In structure all the members are public.
 In oop Public,Private,protected Access specifiers are used.
example: in class data is private & member function is public
#include<iostream.h>
class a
{
private:
data
public:
member function
};

4.  In POP, Most function uses Global data for sharing that can be
accessed freely from function to function in the system.
 In OOP, data can not move easily from function to function, it can be kept public or
private so we can control the access of data.
example: in class the data member declared in private mode are only access
through it’s member function.

5.  POP does not have any proper way for data hiding.
example: in structure data are declared in public mode so it is less secure.
 Oop provides data hiding, so it is more secure.
example: data member declare in private are not accessible outside class.
#Include<iostrean.h>
class a
{
int a;
void read();
public:
Void update();
void write();
};
int main(){
a ob;
ob.read(); //object can not access ,private member
}

6.  Pop program is divided into small parts called function.
 Oop program is divided into small part called object.
 In POP, Importance is not given to data but to functions as well as sequence of actions to be
done
 In OOP, Importance is given to the data rather than procedures or functions because it works as
a real world.

7.  In pop overloading is not possible.
 In oop overloading is possible in the form of function overloading
& operator overloading.
example: overloaded add().
//declaration
int add(int a,int b);
int add(int a,int b,int c);
double add(double x,double y);
double add(double p,double q);

iii. FORTRAN
iv. PASCAL

ii. JAVA,
iii. VB.NET,
iv. C#.NET.
