A programmer notices the following two procedures in a library. The procedures do similar, but not identical, things.

Procedure square (n) returns the value n2

Procedure cube (n) returns the value n3

Which of the following procedures is a generalization of the procedures described above?
A. Procedure Add (n, m), which returns the value n + m
B. Procedure Fourth (n), which returns the value n4
C. Procedure Polynomial(n), which returns the value n3 +n2
D. Procedure Power (n, m), which returns the value nm

D. Procedure Power (n, m), which returns the value n^m

Explanation:

Given

Required

The generalization

The given functions are power functions which returns the power of n to a certain value.

The power sequence follows:

------

-----

--

Hence, (d) is correct

in software engineering and computer science, abstraction is: the process of removing physical, the way that different data types interact, is the beginning of abstraction.
