Here's an example program in C++ that fulfills the requirements:

_______________________________________________________

#include <iostream>

#include <fstream>

#include <vector>

using namespace std;

int main() {

   const int ARRAY_SIZE = 1000; // Set a large size for the array

   double array[ARRAY_SIZE];

   double sum = 0.0;

   int count = 0;

   // Read the first five elements from the keyboard

   cout << "Enter the first five elements of the array:\n";

   for (int i = 0; i < 5; i++) {

       cout << "Element " << i + 1 << ": ";

       cin >> array[i];

       sum += array[i];

       count++;

   }

   // Read the remaining elements from a file

   ifstream inputFile("input.txt"); // Replace "input.txt" with your file name

   double num;

   while (inputFile >> num && count < ARRAY_SIZE) {

       array[count] = num;

       sum += array[count];

       count++;

   }

   inputFile.close();

   // Calculate and print the average

   double average = sum / count;

   cout << "Average of array elements: " << average << endl;

   return 0;

}

________________________________________________________

In this C++ program, a large array of doubles is declared with a size of 1000. The first five elements are read from the keyboard using a for loop, and the sum and count variables keep track of the cumulative sum and the number of elements entered.

The remaining elements are read from a file named "input.txt" (you should replace it with the actual file name) using an ifstream object. The program continues reading elements from the file as long as there are more numbers and the count is less than the array size.

Finally, the average is calculated by dividing the sum by the count, and it is printed to the console. Remember to replace "input.txt" with the correct file name and double-check the average with a calculator to ensure accuracy.

Answer:

A. Encode the (negative) decimal fraction -9/2 to binary using the 8-bit floating-point notation.

First, let's convert -9/2 to a decimal number: -9/2 = -4.5

Now, let's encode -4.5 using the 8-bit floating-point notation. We'll use the following format for 8-bit floating-point representation:

1 bit for the sign (S), 3 bits for the exponent (E), and 4 bits for the mantissa (M): SEEE MMMM

Sign bit: Since the number is negative, the sign bit is 1: 1

Mantissa and exponent: Convert -4.5 into binary and normalize it:

-4.5 in binary is -100.1. Normalize it to get the mantissa and exponent: -1.001 * 2^2

Mantissa (M): 001 (ignoring the leading 1 and taking the next 4 bits)

Exponent (E): To store the exponent (2) in 3 bits with a bias of 3, add the bias to the exponent: 2 + 3 = 5. Now, convert 5 to binary: 101

Now, put the sign, exponent, and mantissa together: 1101 0010

So, the 8-bit floating-point representation of -9/2 (-4.5) is 1101 0010.

B. Determine the smallest (lowest) negative value which can be incorporated/represented using the 8-bit floating-point notation.

To get the smallest negative value, we'll set the sign bit to 1 (negative), use the smallest possible exponent (excluding subnormal numbers), and the smallest mantissa:

Sign bit: 1

Exponent: Smallest exponent is 001 (biased by 3, so the actual exponent is -2)

Mantissa: Smallest mantissa is 0000

The 8-bit representation is 1001 0000. Converting this to decimal:

-1 * 2^{-2} * 1.0000 which is -0.25.

The smallest (lowest) negative value that can be represented using the 8-bit floating-point notation is -0.25.

C. Determine the largest (highest) positive value which can be incorporated/represented using the 8-bit floating-point notation.

To get the largest positive value, we'll set the sign bit to 0 (positive), use the largest possible exponent (excluding infinity), and the largest mantissa:

Sign bit: 0

Exponent: Largest exponent is 110 (biased by 3, so the actual exponent is 3)

Mantissa: Largest mantissa is 1111

The 8-bit representation is 0110 1111. Converting this to decimal:

1 * 2^3 * 1.1111 which is approximately 1 * 8 * 1.9375 = 15.5.

The largest (highest) positive value that can be represented using the 8-bit floating-point notation is 15.5.

a. Proposition 2 states that Insertion-Sort runs in O(n + X) time, where X is the number of inversions.

b. The expected number of inversions, E[X],  E[X] = 1/4n(n-1).

c. In the average case, Insertion-Sort has a time complexity of approximately O(1/4n²).

(a) Proposition 2 states that Insertion-Sort runs in O(n + X) time, where X is the number of inversions. To understand why this is true, let's refer to the pseudocode for Insertion-Sort:

InsertionSort(A):

  for i from 1 to length[A] do

     key = A[i]

     j = i - 1

     while j >= 0 and A[j] > key do

        A[j + 1] = A[j]

        j = j - 1

     A[j + 1] = key

b. The expected number of inversions, E[X], can be calculated as follows:

E[X] = Σ(i,j) E[I(i, j)]

= Σ(i,j) Pr((i, j) is an inversion)

= Σ(i,j) 1/2

= (n(n-1)/2) * 1/2

= n(n-1)/4

Hence, E[X] = 1/4n(n-1).

(c) Using Proposition 2 and the result from part (b), we can determine the average case time complexity of Insertion-Sort. The average case time complexity is given by O(n + E[X]).

Substituting the value of E[X] from part (b):

Average case time complexity = O(n + 1/4n(n-1))

Simplifying further:

Average case time complexity = O(n + 1/4n^2 - 1/4n)

Since 1/4n² dominates the other term, we can approximate the average case time complexity as:

Average case time complexity ≈ O(1/4n²)

Therefore, in the average case, Insertion-Sort has a time complexity of approximately O(1/4n²).

Bubble Sort is a simple sorting algorithm that works by repeatedly swapping adjacent elements if they are in the wrong order. It gets its name from the way smaller elements "bubble" to the top of the list or array during each iteration.

The algorithm continues iterating through the list until the entire list is sorted.

Let's say we have an array of numbers: [5, 2, 8, 12, 1]. To sort this array using Bubble Sort, we compare adjacent elements and swap them if they are in the wrong order. Here's how the algorithm works step by step:

Starting with the first pair of elements, compare 5 and 2. Since 5 is greater than 2, we swap them, resulting in the array [2, 5, 8, 12, 1].

Move to the next pair, which is 5 and 8. They are in the correct order, so no swap is needed.

Compare 8 and 12. Again, they are already in the correct order.

Compare 12 and 1. Since 12 is greater than 1, we swap them, resulting in the array [2, 5, 8, 1, 12].

Repeat steps 1-4 until we reach the end of the array without making any swaps.

Here's a diagram to visualize the steps:

Step 1:

[5, 2, 8, 12, 1]

Step 2:

[2, 5, 8, 12, 1]

Step 3:

[2, 5, 8, 12, 1]

Step 4:

[2, 5, 8, 1, 12]

Step 5:

[2, 5, 8, 1, 12]

In the first iteration, the largest element (12) moved to its correct position at the end of the array. In the second iteration, the second largest element (8) moved to its correct position. This process continues until the entire array is sorted.

The time complexity of Bubble Sort is O(n^2), where n is the number of elements in the array. This means that the time it takes to sort the array grows quadratically with the number of elements. It is not an efficient sorting algorithm for large datasets, but it is simple to understand and implement.

Here are the answers to the questions:

3.1 The two main elements of a CPU are:

The Control Unit (CU): The CU controls and coordinates the operations of the CPU. It is responsible for interpreting instructions and sequencing them for execution.

The Arithmetic Logic Unit (ALU): The ALU executes arithmetic and logical operations like addition, subtraction, AND, OR, etc. It contains registers that hold operands and results.

3.2 The fetch/execute cycle refers to the cycle of events where the CPU fetches instructions from memory, decodes them, and then executes them. The steps in the cycle are:

Fetch: The next instruction is fetched from memory.

Decode: The instruction is decoded to determine what it is asking the CPU to do.

Execute: The CPU executes the instruction. This could involve accessing data, performing calculations, storing results, etc.

Go back to Fetch: The cycle continues as the next instruction is fetched.

3.3 The binary number 00000011 is equal to the decimal number 3.

Binary: 00000011

Decimal: 1 + 2 = 3
