Q.No.3 b. (Marks 3)
Explain why change is inevitable in complex systems and give examples (apart from prototyping and incremental delivery) of software process activities that help predict changes and make the software being developed more resilient to change.

Answer:

Explanation:

The following program asks the user to enter the precinct number and then loops to add votes until no more votes need to be added. Then it breaks the loop and creates a file called results to save all of the results for that precinct.

precinct = input("Enter Precinct Number: ")

option1 = 0

option2 = 0

while True:

   choice = input("Enter your vote 1 or 2: ")

   if int(choice) == 1:

       option1 += 1

   else:

       option2 += 1

   endVote = input("Vote again y/n")

   if endVote.lower() != 'y':

       break

f = open("results.txt", "w")

f.write("Precinct " + precinct + ": \nOption 1: " + str(option1) + "\nOption 2: " + str(option2))

Answer:

self-modeling

Explanation:

Robots, which are man-made machines which mimics the actions of man like walking, talking, rendering assistance are part of the future plans to make the society easier. It was mans' attempt to improve the society but still happens to be work in progress.

For the robots to be able to carryout its function, there is need for it to be self modelling in the sense of initiating and executing the commands which was already programmed into it. For example, telling it to walk will be initiated by him as a command, after processing the command, it will execute it without any other information.

The following program is written in Java and it combines several classes and an interface in order to save different pet objects and their needed methods and specifications.

The choice between biometric fingerprint systems with varying fraud and insult rates depends on the priorities and risks of the merchant and their business.

When choosing between the two biometric fingerprint systems, it's important to consider the trade-off between the fraud rate and the insult rate.

System A has a lower fraud rate of 1%, which means that there is a lower chance that another person is incorrectly authenticated as a legitimate user. However, System A has a higher insult rate of 5%, which means that there is a higher chance that the legitimate user is not successfully authenticated.

On the other hand, System B has a higher fraud rate of 5%, which means that there is a higher chance that another person could be incorrectly authenticated as a legitimate user. However, System B has a lower insult rate of 1%, which means that there is a lower chance that the legitimate user is not successfully authenticated.

Ultimately, the decision of which system to choose would depend on the priorities and risks associated with the specific merchant and their business. They would need to weigh the potential financial loss from fraud against the inconvenience or loss of business from customers who are not successfully authenticated.

Explanation:

The command allows a user to jump from one presentation to another Switch windows.

Flip is similar to the Task view feature, although it operates somewhat differently. Click the Task view button in the taskbar's lower-left corner to launch Task view.

As an alternative, you can use your keyboard's Windows key and Tab. You can click on any open window to select it from a list of all your open windows.

It may be challenging to view the desktop if you have many windows open at once. When this occurs, you can minimize all currently open windows by clicking the taskbar's bottom-right corner. Simply click it once again to bring back the minimized windows.

Therefore, The command allows a user to jump from one presentation to another Switch windows.

Answer:

In Python:

def gcd(m,n):

if n == 0:

 return m

elif m == 0:

    return n

else:

 return gcd(n,m%n)

Explanation:

This defines the function

def gcd(m,n):

If n is 0, return m

if n == 0:

 return m

If m is 0, return n

elif m == 0:

    return n

If otherwise, calculate the gcd recursively

else:

 return gcd(n,m%n)

To call the function to calculate the gcd of say 15 and 5 from main, use:

gcd(15,5)
