Hi!
In 1981, the term 4GL was actually used to refer to languages which were <em>non-procedural. </em>A procedural language does not possess <em>object-oriented </em>capabilities. 4GL's often times have OOP properties, so I believe the answer to this question is going to be <em>false. </em>=)

Big-O notation is a way to describe a function that represents the n amount of times a program/function needs to be executed.
(I'm assuming that := is a typo and you mean just =, by the way)
In your case, you have two loops, nested within each other, and both loop to n (inclusive, meaning, that you loop for when i or j is equal to n), and both loops iterate by 1 each loop.
This means that both loops will therefore execute an n amount of times. Now, if the loops were NOT nested, our big-O would be O(2n), because 2 loops would run an n amount of times.
HOWEVER, since the j-loop is nested within i-loop, the j-loop executes every time the i-loop <span>ITERATES.
</span>
As previously mentioned, for every i-loop, there would be an n amount of executions. So if the i-loop is called an n amount of times by the j loop (which executes n times), the big-O notation would be O(n*n), or O(n^2).
(tl;dr) In basic, it is O(n^2) because the loops are nested, meaning that the i-loop would be called n times, and for each iteration, it would call the j-loop n times, resulting in n*n runs.
A way to verify this is to write and test program the above. I sometimes find it easier to wrap my head around concepts after testing them myself.
Answer:
206.58.170.67 is the decimal format of the given binary IP address.
Explanation:
we can convert the binary number into decimal by the following procedure.
11001110 = 1x2⁷+1x2⁶+0x2⁵+0x2⁴+1x2³+1x2²+1x2¹+0x2⁰
= 128 + 64 + 0 + 0 + 8 + 4 + 2 + 0
= 206
00111010 = 0x2⁷+0x2⁶+1x2⁵+ 1x2⁴+1x2³+0x2²+1x2¹+0x2⁰
= 0 + 0 + 32 + 16 + 8 + 0 + 2 + 0
= 58
10101010 = 1x2⁷+0x2⁶+1x2⁵+ 0x2⁴+1x2³+0x2²+1x2¹+0x2⁰
= 128 + 0 + 32 + 0 + 8 + 0 + 2 + 0
= 170
01000011 = 0x2⁷+ 1x2⁶+ 0x2⁵+ 0x2⁴+ 0x2³+0x2²+1x2¹+1x2⁰
= 0 + 64 + 0 + 0 + 0 + 0 + 2 + 1
= 67
so, the IP address is becomes 206.58.170.67
