Question

How is modular programming different from the procedural programming paradigm?

Answer 1

Modular programming:

• Emphasis on the algorithm rather than data.
• Programs are divided into individual modules.
• Each module is independent of each others and has its own local data.
• Modules can work with their own data as well as with the data passed to it.

Procedural programming:

• Programs are organized in the form of subroutines or sub-programs.
• All data items are global.
• Suitable for small-sized software applications.
• Difficult to maintain and enhance the program code as any change in data type needs to be propagated to all subroutines that use the same data type.
