Answer:
Tell about an experience with a computer virus.
Explanation:
Simon Singh's "The Code Book," tells the history of how cryptography came into being and the secret messaging world of encryption. Through the detailed narration and diving into the history of encryption, the author traces the evolution of such a process and reveals how it has had a huge impact on the world's policies.
In the given excerpt, Singh gives an example of how viruses are planted and used to spy/ get access to other people's computers. But while it is possible to get the main point of the example, <u>it would have been better if the writer includes experience with a computer virus</u> so that readers will find it easier to connect with the given example. This will enable them to better understand the working of viruses and their effects.
Thus, the correct answer is the first option.
Answer:
The program in Python is as follows:
n = int(input("n:"))
total = 0
for k in range(1,n+1):
total+=k**3
print(total)
Explanation:
This gets input for n
n = int(input("n:"))
This initializes total to 0
total = 0
This iterates from 1 to n
for k in range(1,n+1):
This adds up the cube of each digit
total+=k**3
This prints the calculated total
print(total)
