Maintainability

In the preceding sections, we have seen a number of features that C++ offers, and the viability of using them on a resource-limited platform. A big advantage of using C++ is the reduction in code size you can accomplish through the use of templates, along with the organization and modularization of a code base using classes, namespaces, and the like.

By striving for a more modular approach in your code, with clear interfaces between modules, it becomes more feasible to reuse code between projects. It also simplifies the maintenance of code by making the function of a particular section of code clearer and providing clear targets for unit and integration testing.
