To find all the prime numbers less than or equal to a given integer n by Eratosthenes' method: 1. Create a list of consecutive i

natta225 [31]

Answer:

I am writing a Python program:

def Eratosthenes(n):

primeNo = [True for i in range(n+1)] # this is a boolean array

p = 2 # the first prime number is initialized as 2

while (p * p <= n): # enumerates all multiples of p

if (primeNo[p] == True):

for i in range(p * p, n+1, p): #update multiples

primeNo[i] = False

p = p + 1

for p in range(2, n): #display all the prime numbers

if primeNo[p]:

print(p),

def main(): #to take value of n from user and display prime numbers #less than or equal to n by calling Eratosthenes method

n= int(input("Enter an integer n: "))

print("The prime numbers less than or equal to",n, "are: ")

Eratosthenes(n)

main()

Explanation:

The program contains a Boolean type array primeNo that is initialized by True which means that any value i in prime array will be true if i is a prime otherwise it will be false. The while loop keeps enumerating all multiples of p starting from 2, and striking them off from the original array list and for loops keep updating the multiples. This process will continue till the p is greater than n. The last for loop displays all the prime numbers less than or equal to n which is input by user. main() function prompts user to enter the value of integer n and then calls Eratosthenes() function to print all the prime numbers less than or equal to a given integer n.

When a program lets the user know that an invalid menu choice has been made, this is an example of?

kolezko [41]

The question has the multiple choices below

A) Input validation
B) output correction
C) compiler criticism
D) output validation

The answer is (A) Input validation

Also known as data validation, it is the correct and proper testing of any input supplied by an application or a user. It prevents wrongly formed data from entering the system. Applications should be able to check and validate every input entered into the system since it is hard to detect a malicious user trying to gain entry into software.

Write a function max_magnitude() with two integer input parameters that returns the largest magnitude value. Use the function in

JulsSmile [24]

Answer:

def max_magnitude(user_val1, user_val2):

if abs(user_val1) > abs(user_val2):

return user_val1

else:

return user_val2

if __name__ == '__main__':

n1 = int(input("Enter the first integer number: "))

n2 = int(input("Enter the second integer number: "))

print("The largest magnitude value of", n1, "and", n2, "is", max_magnitude(n1, n2))

_____________ is the characteristic of a resource that ensures that access is restricted to only permitted users, applications,

Maksim231197 [3]

Answer:

The answer to this question is "Confidentiality".

Explanation:

The answer is Confidentiality because in any computer system many files are important for there user. If the file was deleted, corrupted or stolen from the computer. So the user faces the difficulty to avoid this type of problem computer system provides a technique that is access control or it is also known as Confidentiality. It is a technique that controls who or what type of user's use of resources in a computing environment.

So the answer to this question is Confidentiality.
