Bob knows the number of tens of X but not the number of ones.

Alice and Bob exchange the following messages.

(a) Bob to Alice: ’You might know X’.
(b) Alice to Bob: ’I did not, but, after what you have said, I do’.

Based on the above information, please answer the following questions. For each question, please accompany your answer with a short explanation of why your believe your answer is correct. Marks will not be awarded for answers without any explanation.

(a) Based on the statement of Bob it is possible to narrow down candidates for the number of tens from the initial five possibilities down to just two. What are these two possibilities? (7 marks)
(b) Based on the ’I did not’ statement of Alice, the number of candidates for X can be narrowed down to just three. What are these candidates (6 marks)
(c) The remaining part of Alice’s statement allows to identify X precisely. What is X? (7 marks)

2. In this section you will be shown several classes. Inside the code for each class will be a question. You should provide your answer to the question inside the chart. Many of the questions will ask you whether a variable has changed or not. In cases that the variable being asked about is a primitive type, you should provide your answer based on the data stored in the primitive type. In cases that the variable being asked about is a reference type, you should provide your answer based on the data stored at the Object linked to by the reference type. For example, in the first snippet, the question asks about the variable x defined in the main method. Since x is a primitive type, you should answer YES if you think the variable x has had its value changed after the method methodOne() returns. All your answers should go in the chart below: (9 points) Part Answer to question x changed (circle one)? YES NO y changed (circle one)? a changed (circle one)? b changed (circle one)? d1 a changed (circle one)? b changed (circle one)? YES e words changed (circle one)? YES NO Values in array of array referred to by y: What is printed to the screen? (a) public class ReferenceTesti public static void methodOne (int x){ x++; public static void main(String[args) { int x = 0; methodOne (x); //IS THE DATA STORED OR REFERRED TO BY X THE SAME? (ANSWER IN CHART)

Answer the following short questions. Your answer should be precise.

Can we declare base class constructor or destructor as virtual if yes then why we want to do?
How we can declare a class as abstract and why we need abstract classes?
Why we cannot able to create objects of abstract classes give reasonable justification of that.

This question is related to Object orientated programming in c++
