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:C)User interface
Explanation: User interface(UI) is the interaction phase of the user or programmer with the computer system and network. This phase helps the user to connect with the operating system function and let them process it according to the requirement. Example-monitor , keyboard, mouse etc.
Other options that are given are incorrect because operating system is the system that is part of the interface , information is the data and storage is for the storing of data,.Thus the correct option is option(C)
Geofencing Marketing refers to the use of gps or rfid technology to create virtual boundaries that enable software to trigger a response when a mobile device enters or leaves a particular area.
<h3>What is Geofencing Marketing?</h3>
- Geofencing marketing is an illustration of a real-time location-based trade tactic that utilizes geolocation data to mark users within a specified geographic region and delivers a range based on where they are or in what areas they have previously visited.
- Geofencing marketing concerns setting up virtual borders around a point or area that tracks whenever someone with a portable device crosses them.
