Difference Between POP & OOP

POP and OOP are two major programming methodologies. OOP offers more features for data security, reuse, and extension, while POP is simpler.

1. Program Division: POP divides a program into small parts (Functions). OOP divides a program into Objects.

2. Approach: POP follows a Top-Down approach. OOP follows a Bottom-Up approach.

3. Data Hiding: POP does not support data hiding, which reduces security. OOP supports data hiding, which increases security.

4. Access Specifiers: POP has no access specifiers. OOP has access specifiers like Public, Private, Protected.

5. Program Extension: In POP, adding new data or functions requires modifying the program. In OOP, new data and functions can be added without modifying the program.

6. Program Size: Managing large programs is difficult in POP. Managing large programs is easy in OOP.

7. Abstraction: POP uses Procedure Abstraction. OOP uses Data Abstraction.

8. Overloading: POP does not support overloading. OOP allows Function Overloading and Operator Overloading.

9. Data Transfer: In POP, data can be passed from function to function. In OOP, data is private and cannot be directly shared between functions.

10. Inheritance: POP does not support inheritance. OOP has the concept of inheritance.

11. Examples: POP examples include C, Visual Basic, Fortran, Pascal. OOP examples include C++, Java, .NET.
