Difference between Procedure/structure oriented programming and object oriented programming

Procedure/ structure oriented Programming

• Conventional programming, using high level languages such as COBOL, FORTRAN and C, is

commonly known as procedure-oriented programming (POP).

• In the procedure-oriented approach, the problem is viewed as a sequence of things to be done

such as reading, calculating and printing. A number of functions are written to accomplish these

tasks.

• The primary focus is on functions.

Object Oriented Programming

• Emphasis is on data rather than procedure.

• Programs are divided into what are known as objects.

• Data is hidden and cannot be accessed by external functions.

• Objects may communicate with each other through functions.

• New data and functions can be easily added whenever necessary.
