Answer:
// program in Python to check perfect number
#function to find number is perfect or not
def is_Perfect_Number(n):
#total variable
tot = 1
i = 2
#sum of all divisor of number
while i*i<=n:
if n%i==0:
tot = tot + i + n/i
if tot == n and n != 1:
return 1
i = i+1
return 0
#read until user enter a perfect number
while True:
#read integer
num = int(input("Input an integer: "))
#call the function
if(is_Perfect_Number(num)):
print(num,"is perfect number")
#if perfect number break
break
else:
print(num,"is not a perfect number")
#ask again
print("try again.")
Explanation:
Read number from user and then call the function is_Perfect_Number() with parameter "num".This will find the sum of all divisor of number.If sum is equal to number then it will return 1 else return 0.If the number is not perfect then it will again ask to enter a number until user enter a perfect number.
Output:
Input an integer: 24
24 is not a perfect number
try again.
Input an integer: 28
28 is perfect number
Answer:
D. ReFS
Explanation:
File system is simply a management system for files that controls how and where data are stored, where they can be located and how data can be accessed. It deals with data storage and retrieval.
Examples of file system are NTFS, FAT(e.g FAT 16 and FAT 32), ReFS.
ReFS, which stands for Resilient File System, is designed primarily to enhance scalability by allowing for the storage of extremely large amounts of data and efficiently manage the availability of the data. It is called "resilient" because it ensures the integrity of data by offering resilience to data corruption. It does not support transaction, encryption, file based compression, page file and disk quotas, to mention a few.
The answer is : True. An audit trail is a record of how a transaction was handled from input through processing and output. An audit trail is the evidence, such as purchase orders and invoices, that a financial transaction actually occurred.
C. Underline because it is not a kind of font. it is an effect.
