Object-oriented programming style

OOPs is a style of computer programming that represents concepts as objects that have states and behaviors. e.g. objective-c, c#, Java.

Difference between Object Oriented Programming and Procedural Programming.

Procedural Programming	Object-Oriented Programming
In Procedural Programming, a program is created in a step-by-step instructional format and instructions are executed in order. Follow a top-down approach. Less secure because it does not have any proper way of data hiding. Does not provide a code re-usability feature. Doesn’t provide the ability to simulate real-world events much more effectively. Slow development.	In Object Oriented Programming a program is created in a way such as real world works. Follow bottom to top approach. Secure because it has a proper way of data hiding. Provide code reusability feature. Provide the ability to simulate real-world events with more effect. Fast Development.

Object-oriented language	Object-based language
Supports all the features of OOPs. Doesn’t have an in-built object. E.g. C#, Java etc.	Doesn’t support all the features of OOPs (like Inheritance, and polymorphism). Has an in-built object (like a window object in JavaScript). E.g. JavaScript, VB, etc.
