Answer:
C. But
Explanation:
Boolean operators are the operators that may have only two outputs which are True/False, On/Off and 1/0.
"But" can also be the example of Boolean operator. It is used in the meaning of "except" or "other than".
In Boolean operators "But" can be used as "AND" operator.
for example
<em>I am busy but I will go.</em>
In above example but is used as and which is combining two oposite statements. as
I am busy and I will go.
Both statement oppose each other, so to make sense in English "But" is used.
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
