Question

What is the purpose of data abstraction?

a.

To make the implementation-independent interfaces public.

b.

To impose the result on all other components.

c.

To avoid repetition of instruction sequences.

d.

To explicitly model control abstraction.

Posted under Software Engineering

Answer: (a).To make the implementation-independent interfaces public. Explanation:The purpose of data abstraction is to create a separate subproblem and make only the procedural, implementation-independent interfaces public, rather than making decisions about data structures and their representation at an early stage and imposing the result on all other components.
