Answer: Non-functional
Explanation:
Non-functional requirement(NFR) are the the requirements that evaluates operation of any particular system.It consist of several factors for judging the system such as security, reliability, quality, utility, maintainability etc.These parameters depicts about how a system will perform the tasks.
Other options are incorrect because function requires are used for depicting about specific and certain function in system. Performance requirements deal with the parameter of operation execution.
Correctness and standard requirement are measure for correcting system and general needs in a system respectively.
Answer:
// here is code in C++.
#include <bits/stdc++.h>
using namespace std;
// main function
int main()
{
// variables
int n;
double average,sum=0,x;
cout<<"enter the Value of N:";
// read the value of N
cin>>n;
cout<<"enter "<<n<<" Numbers:";
// read n Numbers
for(int a=0;a<n;a++)
{
cin>>x;
// calculate total sum of all numbers
sum=sum+x;
}
// calculate average
average=sum/n;
// print average
cout<<"average of "<<n<<" Numbers is: "<<average<<endl;
return 0;
}
Explanation:
Read the total number from user i.e "n".Then read "n" numbers from user with for loop and sum them all.Find there average by dividing the sum with n.And print the average.
Output:
enter the Value of N:5
enter 5 Numbers:20.5 19.7 21.3 18.6 22.1
average of 5 Numbers is: 20.44
If you have purchased a printer that has the capability to print in duplex mode so that users can print on both sides of a sheet of paper. However, when users try to use this capability when they send a print job, documents are still printed on only one side. Then there might be a problem with (d) THE DUPLEX MODE NEEDS TO BE ENABLED ON THE DEVICE SETTINGS TAB IN THE PRINTER'S PROPERTIES.
Explanation:
- If the duplex mode isn't enable on the printer setting, then the printer is still going to read that the output should come in a single page and not in the duplex mode.
- When facing such a problem, the user should go to the "Device Settings" tab in the printer properties and change the required settings to print according to the users needs.
Answer:
Explanation:
The following code is written in Python. It asks the user for an input. Then cleans the input using regex to remove all commas, whitespace, and apostrophes as well as making it all lowercase. Then it reverses the phrase and saves it to a variable called reverse. Finally, it compares the two versions of the phrase, if they are equal it prints out that it is a palindrome, otherwise it prints that it is not a palindrome. The test case output can be seen in the attached picture below.
import re
phrase = input("Enter word or phrase: ")
phrase = re.sub("[,'\s]", '', phrase).lower()
reverse = phrase[::-1]
if phrase == reverse:
print("This word/phrase is a palindrome")
else:
print("This word/phrase is NOT a palindrome")
