Answer:
Place:
Coffee shop. Railway Reservation System, Airport Reservation System, Machine learning and a long list follow.
Situation:
We find that there is a similar type of calculation and in bulk. Thus we can create a piece of software, and run that with the help of a computer to solve our problem of tackling the massive number of clients.
Description:
The situation demands a similar sort of calculation, and we can hence make a program or most favorably a software that can do all these calculations for us. A perfect example is a coffee shop, which has 100 to 1000 customers drinking coffee each second. And you can understand how badly they need a computer and software. This cannot be done manually.

Please check the answer section.
Answer:
2. <em>A reference of type A can be treated as a reference of type B</em> - False
Base class or its objects are not related to their derived class (or its objects).
Explanation:
class A {
int a;
public A() {
a = 7;
}
}
class B extends A {
int b;
public B() {
b = 8;
}
}
///////////////////////////////////////////////////////////////////////////////////////////////////////
1. <em>After the constructor for class B executes, the variable a will have the value 7 </em>- True.
When an object of a derived class is declared, the constructor of base class is called before the constructor of derived class (is called).
3. <em>Both variables a and b are instance variables </em>- True.
Classes can have instance, or member, variables and methods.
4.<em> After the constructor for class B executes, the variable b will have the value 8</em> - True.
When object of class B is declared, its constructor was called, which initialized variable b to 8.
Answer:
- common = []
- num1 = 8
- num2 = 24
- for i in range(1, num1 + 1):
- if(num1 % i == 0 and num2 % i == 0):
- common.append(i)
- print(common)
Explanation:
The solution is written in Python 3.
Firstly create a common list to hold a list of the common factor between 8 and 24 (Line 1).
Create two variables num1, and num2 and set 8 and 24 as their values, respectively (Line 3 - 4).
Create a for loop to traverse through the number from 1 to 8 and use modulus operator to check if num1 and num2 are divisible by current i value. If so the remainder of both num1%i and num2%i will be zero and the if block will run to append the current i value to common list (Line 6-8).
After the loop, print the common list and we shall get [1, 2, 4, 8]
False
Not all IT services are equally critical. In an increasingly
digital world whereby cyber threats are a big threat, it is vital to prioritize
the critical assets in order to achieve digital resilience. This involves
building tighter defenses in systems that are critical.
