What is the difference of modular programming and modular programming?

Answer 1

The strength of modular programming lies in the modular approach. Each module holds logically grouped code (functions, procedures, variables, constant data), typically grouped by functionality.

For instance, one module might provide tools to retrieve application-specific data from and store such data in a database, another module might provide visualization primitives, a third might provide an application-specific data structure and related management functions, etc.

As each module is developed, it is tested as a single unit. The idea is to perfect this module, and never to touch it again while the remaining modules are being developed and tested in a similar manner, then put together ("integrated") to form the application.

While the goal of never touching a module, once initially tested, is rarely met in real life terms, modular programming provides a structured approach to application design and helps in producing quality software. A modular design also helps when working in a team, as the modules' boundaries often are natural dividing lines along which the work can be divided between different members of the team.
