Multi-Paradigm Programming with Modern C++ - What Makes a Good Interface

The video discusses what makes a good interface, focusing on APIs as contracts between program parts. It explains that a good interface provides a minimally complete model, is explicit, meets user expectations, and offers non-leaky abstractions. The importance of interfaces is highlighted, noting that they significantly impact application behavior. The video concludes with a preview of improving interfaces through better abstractions.

What is an API primarily described as in the context of software development?

• A contract between two parts of a program

• A tool for debugging code

• A user interface for end users

• A method for data storage

Which of the following is NOT a characteristic of a good interface?

• Uses void pointers to pass data

• Describes available states and conditions

• Is explicit and consistent

• Provides a minimally complete model

What does a non-leaky abstraction in an interface mean?

• It provides direct access to hardware

• It hides implementation details effectively

• It exposes all internal workings

• It allows for dynamic memory allocation

Why is it important for an API to meet user expectations?

• To maintain consistency and strong typing

• To allow for faster execution

• To ensure it is visually appealing

• To reduce the need for documentation

According to the C core guidelines, what percentage of code defines most of an application's behavior?

• 10%

• 50%

• 20%

• 80%
