Answer: C. File encryption
Explanation: To ensure security and privacy of files and its content, encrypting the file may be an option. File encryption refers to a process of ensuring the security and privacy of individual files so as to prevent unauthorized access to the content. File encryption works by setting up a security key which will be requested or needed when the file is being clicked such that only users or individuals with the authorized pass code or password can open and read its content or modify the file, this is called file decryption.
Answer:
Following are the program in python language the name of the program is factors.py
num= int(input("Please enter a positive integer: "))#Read the number by user
print("The factors of ",num,"are:")
for k in range(2,num): #iterating over the loop
if(num%k==0): #checking the condition
print(k)#display the factor
Output:
Please enter a positive integer: 12
The factors of 12 are:
2
3
4
6
Explanation:
Following are the description of the program
- Read the number by user in the "num" variable
- Iterating the for loop from k=2 to less then "num".
- In the for loop checking the factor of "num" variable by using % operator.
- Finally display the factor by using print function
Answer:
The algorithm to find A is even or odd.
- input A.
- Check the remainder on diving by 2 by A%2.
- If remainder is 1 then A is odd Print(Odd).
- If remainder is 0 print(Even).
Explanation:
To check if the number is even or odd we use modulo operator(%).Which gives the remainder on dividing.So if we do this A%2 it will give the remainder that will come out on dividing the value of A by 2.
So if the remainder comes out is 1 then the number is odd and if the remainder is 0 then the number is odd.
