Answer:

The correct answer to the question is option A "None of the mentioned"

Explanation:

Functional requirements describe the component of a system by verifying the functionality of the software, defines what function a system is likely to perform. It simply dictates to the system/software on how it must behave. For example, it commands software to display, for instance, User name, total orders placed, and a lot of other commands. It puts the computer/software to describe what the product has to do.

Nonfunctional requirements describe the general quality of a system describing how it works.

In the options above, Maintainability allows modification of applications, robustness allows a system to function well even after an interruption with an error command, and Portability allows easy running and the ability for software to be transferred easily, are all examples of non-functional requirements.

Gelneren [198K]

Using the computational knowledge in python it is possible to write a code that Write a recursive function called digit_count()

<h3>What is a function in Python?</h3>

In Python, a function is a sequence of commands that performs some task and that has a name. Its main purpose is to help us organize programs into chunks that correspond to how we envision a solution to the problem.

<h3>Writting the code in python:</h3>

<em>def countDigits(n):</em>

<em>   if n< 10:</em>

<em>      return 1</em>

<em>   else:</em>

<em>       return 1 + countDigits(n / 10)</em>

What are the values of the following expressions? In each line assume that,
MissTica

Answer:

double x = 2.5;

double y = -1.5;

int m = 18;

int n = 4;

string s = "Storm";

string t = "Watch";

The output of the expression "x + n*y - (x+n)*y" is "6.25".

and the output of expression "m/n + m%n" is "6".

Explanation:

for the first expression,

x + n*y - (x+n)*y ,put value of every variables in it.

=2.5+4*(-1.5)-(2.5+4)*(-1.5)

=2.5-6.0-(6.5*(-1.5)

=-3.5+9.75

=6.25

for the second expression,

m/n + m%n,  put value of every variables in it.

=18/4 +18%4

=4+2      ("/ will give quotient and % will give remainder")

=6
