Answer:
The program written in Python is as follows:
<em>See Explanation section for line by line explanation</em>
for n in range(100,1000):
isum = 0
for d in range(1,n):
if n%d == 0:
isum += d
if isum == n * 2:
print(n)
Explanation:
The program only considers 3 digit numbers. hence the range of n is from 100 to 999
for n in range(100,1000):
This line initializes sum to 0
isum = 0
This line is an iteration that stands as the divisor
for d in range(1,n):
This line checks if a number, d can evenly divide n
if n%d == 0:
If yes, the sum is updated
isum += d
This line checks if the current number n is a double-perfect number
if isum == n * 2:
If yes, n is printed
print(n)
<em>When the program is run, the displayed output is 120 and 672</em>
Python:
sentence = “this is the sentence.”
size = len(sentence)
C++:
string sentence = “this is the sentence.”
int size = sentence.size()
* Remember strings are just arrays of characters.

Answer:
TTL
Explanation:
TTL means time -to- live field is a counter that is designed to keep packets from circulating indefinitely in the network case forwarding tables accidentally create cycles. An IP datagram is typically initialized with a TTL of 60 or 64 and the TTL is decremented by one each time it enters a router. If the TTL reaches zero, the router will discard the packet. It is one of the components of the IP datagram
