The statements regarding the design principle ‘information hiding’ that are true and false are as follows:

True:

Adhering to the ‘information hiding’ principle increases flexibility for modifications (A).

Information hiding involves deliberately hiding information from callers or consumers of the building block (B).

In object-oriented development, information hiding is primarily relevant at class level (E).

False:

Information hiding makes it harder to distinguish between interface and implementation C.

Information hiding is a derivative of the approach of incremental refinement along the control flow (D).

The principle of ‘information hiding’ is a fundamental concept in software engineering that promotes encapsulation and abstraction. Here’s an explanation of each statement:

True Statements:

(A): Information hiding allows for changes in the implementation without affecting other parts of the system, thus increasing flexibility1.

(B): The core idea of information hiding is to keep the implementation details away from the users of the component, revealing only what is necessary2.

(E): In object-oriented programming, information hiding is typically applied at the class level, where internal data and methods are hidden from other classes3.

False Statements:

C: Information hiding does not make it harder to distinguish between interface and implementation; rather, it helps to clearly define the interface by hiding the implementation details1.

(D): Information hiding is not a derivative of incremental refinement along the control flow; it is a separate principle that focuses on hiding the internal complexities of a component4.

Information hiding is crucial for maintaining a clean and modular architecture, where components can be developed, maintained, and replaced independently.
