I can see the application of template classes for containers
Most containers and generic functions are library code
I don’t write libraries
What’s the point of me using templates?

In this article we’re going to look at an application of templates beyond writing library code – replacing run-time polymorphism […]

Interfaces

One of our key design goals is to reduce coupling between objects and classes. By keeping coupling to a minimum a design is more resilient to change imposed by new feature requests or missing requirements[1].

An Interface represents an abstract service. That is, it is the specification of a set of behaviours (operations) that represent a problem that needs to be solved.

An Interface is more than a set of cohesive operations. The Interface can be thought of as a contract […]
