Structured Programming
| Object-Oriented Programming
|
| It is a subset of procedural programming. | It relies on concept of objects that contain data and code. |
| Programs are divided into small programs or functions. | Programs are divided into objects or entities. |
| It is all about facilitating creation of programs with readable code and reusable components. | It is all about creating objects that usually contain both functions and data. |
| Its main aim is to improve and increase quality, clarity, and development time of computer program. | Its main aim is to improve and increase both quality and productivity of system analysis and design. |
| It simply focuses on functions and processes that usually work on data. | It simply focuses on representing both structure and behavior of information system into tiny or small modules that generally combines data and process both. |
| It is a method of organizing, managing and coding programs that can give or provide much easier modification and understanding. | It is a method in which set of objects can vary dynamically and can execute just by acting and reading to each other. |
| In this, methods are written globally and code lines are processed one by one i.e., Run sequentially. | In this, method works dynamically, make calls as per need of code for certain time. |
| It generally follows “Top-Down Approach”. | It generally follows “Bottom-Up Approach”. |
| It provides less flexibility and abstraction as compared to object-oriented programming. | It provides more flexibility and abstraction as compared to structured programming. |
| It is more difficult to modify structured program and reuse code as compared to object-oriented programs. | It is less difficult to modify object-oriented programs and reuse code as compared to structured programs. |
| It gives more importance of code. | It gives more importance to data. |
