Chapter 6.7, Problem 6.4.1ITA
Explanation of Solution
Few quality control issues with Massive Open Online Courses:
Quality of tests being used:
Students have the biggest concern about the tests being conducted in these type of courses. As the quality of the test improves, even the quality of student and course improves.
Quality of courses:
The most important factor of any course is the quality, as a student prefers the better quality courses which suits his/her interests.
Quality of instructors managing the course:
A good instructor can help the student to grasp the topics more easily and quickly. Therefore, it is always a matter of concern.
Problems related to any interaction between students:
In a country like India, there are variety of people with variety in their beliefs and knowledge which may sometimes cause a problem when two students interact or it is also possible that the students are not allowed to interact which may again become a problem...

Objective:
1. Implement a custom Vector class in C++ that manages dynamic memory efficiently.
2. Demonstrate an understanding of the Big Five by managing deep copies, move
semantics, and resource cleanup.
3. Explore the performance trade-offs between heap and stack allocation.
Task Description:
Part 1: Custom Vector Implementation
1. Create a Vector class that manages a dynamically allocated array.
。 Member Variables:
°
T✶ data; // Dynamically allocated array for
storage.
std::size_t size; // Number of elements currently
in the vector.
std::size_t capacity; // Maximum number of
elements before reallocation is required.
2. Implement the following core member functions:
Default Constructor: Initialize an empty vector with no allocated storage.
。 Destructor: Free any dynamically allocated memory.
。 Copy Constructor: Perform a deep copy of the data array.
。 Copy Assignment Operator: Free existing resources and perform a deep
copy.
Move Constructor: Transfer ownership of the data array…
2.68♦♦
Write code for a function with the following prototype:
* Mask with least signficant n bits set to 1
* Examples: n = 6 -> 0x3F, n = 17-> 0x1FFFF
* Assume 1 <= n <= w
int lower_one_mask (int n);
Your function should follow the bit-level integer coding rules
Be careful of the case n = W.
Hi-Volt Components
You are the IT manager at Hi-Voltage Components, a medium-sized firm that makes specialized circuit
boards. Hi-Voltage's largest customer, Green Industries, recently installed a computerized purchasing sys-
tem. If Hi-Voltage connects to the purchasing system, Green Industries will be able to submit purchase
orders electronically. Although Hi-Voltage has a computerized accounting system, that system is not
capable of handling EDI.
Tasks
1. What options does Hi-Voltage have for developing a system to connect with Green Industries' pur-
chasing system?
2. What terms or concepts describe the proposed computer-to-computer relationship between
Hi-Voltage and Green Industries?
why not?
3. Would Hi-Voltage's proposed new system be a transaction processing system? Why or
4. Before Hi-Voltage makes a final decision, should the company consider an ERP system? Why or
why not?

- Assume that a string of name & surname is saved in S. The alphabetical characters in S can be in lowercase and/or uppercase letters. Name and surname are assumed to be separated by a space character and the string ends with a full stop "." character. Write an assembly language program that will copy the name to NAME in lowercase and the surname to SNAME in uppercase letters. Assume that name and/or surname cannot exceed 20 characters. The program should be general and work with every possible string with name & surname. However, you can consider the data segment definition given below in your program. .DATA S DB 'Mahmoud Obaid." NAME DB 20 DUP(?) SNAME DB 20 DUP(?) Hint: Uppercase characters are ordered between 'A' (41H) and 'Z' (5AH) and lowercase characters are ordered between 'a' (61H) and 'z' (7AH) in the in the ASCII Code table.

- A design for a synchronous divide-by-six Gray counter isrequired which meets the following specification.The system has 2 inputs, PAUSE and SKIP:• While PAUSE and SKIP are not asserted (logic 0), thecounter continually loops through the Gray coded binarysequence {0002, 0012, 0112, 0102, 1102, 1112}.• If PAUSE is asserted (logic 1) when the counter is onnumber 0102, it stays here until it becomes unasserted (atwhich point it continues counting as before).• While SKIP is asserted (logic 1), the counter misses outodd numbers, i.e. it loops through the sequence {0002,0112, 1102}.The system has 4 outputs, BIT3, BIT2, BIT1, and WAITING:• BIT3, BIT2, and BIT1 are unconditional outputsrepresenting the current number, where BIT3 is the mostsignificant-bit and BIT1 is the least-significant-bit.• An active-high conditional output WAITING should beasserted (logic 1) whenever the counter is paused at 0102.(a) Draw an ASM chart for a synchronous system to providethe functionality described above.(b)…arrow_forwardS A B D FL I C J E G H T K L Figure 1: Search tree 1.
