Object-oriented programming vs. procedural oriented programming

Object-oriented programming

Procedural oriented programming

• Divided into small parts called objects

• Deals with data

• Follows a bottom-up approach involving object invoking

• More secure due to abstraction

• Comparatively more code reuse

• Overloading is possible

• Adding new functions and data to the existing code is really easy

• Has no access specifiers that can be used

• Needs more memory than PP

• Examples: .NET, Java, C++

• Divided into small parts called functions

• Deals with algorithms

• Follows a top-down approach involving function calling

• Less secure than OOP

• Limited code reuse

• Overloading is not possible

• Adding new functions and data to the existing code is not easy

• Has no access specifiers like public, private, and protected

• Needs less memory than OOP

• Examples: C, QBASIC, Fortran
