Chapter 2.1, Problem 2.5PP

A.

Program Plan Intro

Byte ordering:

  • Some machines decide to store the objects in memory ordered from least significant byte to most, while other machines store them from most to least.
  • The byte ordering are made by the two ways:
    • Little Endian
      • In little Endian, the least significant byte comes first.
    • Big Endian
      • In big Endian, the most significant byte comes first.

Example:

The example for find the little-endian and big-endian for hexadecimal value is shown below:

Here assume that the hexadecimal value is “0x13244860”. Then address range for given ordering byte is “0x200” through “0x203”.

Big Endian for given hexadecimal value is

0x2000x2010x2020x203
13244860

Little Endian for given hexadecimal value is

0x2000x2010x2020x203
60482413

From the given question, the function definition for “show_bytes” is

void show_bytes(byte_pointer start, size_t len) {

int i;

for (i = 0; i < len; i++)

printf(" %.2x ", start[i]);

printf(“\n”);

}

The function “show_bytes” is used to show the address of a sequence of bytes indicated a byte pointer and a byte length.

Suppose you buy an electronic device that you operate continuously. The device costs you $300 and carries a one-year warranty. The warranty states that if the device fails during its first year of use, you get a new device for no cost, and this new device carries exactly the same warranty. However, if it fails after the first year of use, the warranty is of no value. You plan to use this device for the next six years. Therefore, any time the device fails outside its warranty period, you will pay $300 for another device of the same kind. (We assume the price does not increase during the six-year period.) The time until failure for a device is gamma distributed with parameters α = 2 and β = 0.5. (This implies a mean of one year.) Use @RISK to simulate the six-year period. Include as outputs (1) your total cost, (2) the number of failures during the warranty period, and (3) the number of devices you own during the six-year period. Your expected total cost to the nearest $100 is _________,…
Which one of the 4 Entities mention in the diagram can have a recursive relationship?    If a new entity Order_Details is introduced, will it be a strong entity or weak entity? If it is a weak entity, then mention its type (ID or Non-ID, also Justify why)?
Please answer the JAVA OOP Programming Assignment scenario below: Patriot Ships is a new cruise line company which has a fleet of 10 cruise ships, each with a capacity of 300 passengers. To manage its operations efficiently, the company is looking for a program that can help track its fleet, manage bookings, and calculate revenue for each cruise. Each cruise is tracked by a Cruise Identifier (must be 5 characters long), cruise route (e.g. Miami to Nassau), and ticket price. The program should also track how many tickets have been sold for each cruise. Create an object-oriented solution with a menu that allows a user to select one of the following options: 1. Create Cruise – This option allows a user to create a new cruise by entering all necessary details (Cruise ID, route, ticket price). If the maximum number of cruises has already been created, display an error message. 2. Search Cruise – This option allows to search a cruise by the user provided cruise ID. 3. Remove Cruise – This op…
