nstructions: For this lab, you will write a program that reads in a list of items for a camera store. The items for the list are in a file called InventoryFile.txt. The program will give the user options to insert an item, remove an item, display the list of items, search for an item, or exit the program. Each line of the file InventoryFile has the following format: Item Number - an integer Number in stock - an integer (between 0 and 999) Unit Price - a floating-point value Minimum inventory level - an inte.

CST 280 In-Class Practice – Week 13
Use this page as a worksheet to sketch the progression of the elements up to the first
split for the QuickSort algorithm. Use the middle array element as the split value:
15 34 99 42 11 41 66 23 55 93 48
Next, access the file quickSort.cpp from the course web page. Tailor the program
by entering the array values above in place of the integer values used for an in-class
demonstration. Be sure to adjust the index range to match the size of this array.
Remember that the parameters to the QuickSort algorithm are starting and ending index
values, not the size of the array.
Next, insert code to demonstrate the state of the array after the first split. This should
verify what you did by hand above. Insert the following code at various points within
the partition function to “see” the array at various stages of processing:
for (int i = start; i <= end; i++) // <== ADD
cout << set[i] << ' ';
cout << endl;
Insert the code at these positions:
int partition(int set[], int start, int end)
{
int pivotValue, pivotIndex, mid;
mid = (start + end) / 2;
swap(set[start], set[mid]);
pivotIndex = start;
pivotValue = set[start];
ç HERE
for (int scan = start + 1; scan <= end; scan++)
{
if (set[scan] < pivotValue)
{
pivotIndex++;
swap(set[pivotIndex], set[scan]);
}
ç HERE
}
swap(set[start], set[pivotIndex]);
ç HERE
return pivotIndex;
}
Finally, identify the line that matches what you concluded above.
Deliverables:
Deliver the following for this assignment:
• This work sheet with a sketch of the array first split
• Program source code with required change
• Program output demonstrating array configuration after first split .

Threads and Callbacks for Embedded Python
Python is a great choice to be customized plug-ins for existing applications. Extending existing applications with Python program is also practical. For large systems, multi-thread programming is ubiquitous along with asynchronous programming, such as event routing. This presentation focuses on dealing with threads and callbacks while embedding Python in other applications.
Develop an inventory management system for an electronics store. The .pdf
Develop an inventory management system for an electronics store. The inventory system should
have the following functionalities .BuildInventory: reada text file containing electronics products
information and store them in an array of pointers .Shownventory display all inventory items
.ShowDefectInventory: display inventory items that are defective Terminate: to save cument
inventory to a text file This lab assignment illustrates the following concepts: -Text file readings
and writings .Arrays of pointers and dynamic memory allocations with new and delete
Inheritance .C++ type casting: static cast Class Design You need at least three classes class
Inventory System: (minimum implementation specified below). This class stores Inyentoryltem
objects (which are in fact Inventory item base class pointers to derived Product objects and
member functions to manipulate those Product objects as shown below. .Private data members
Store Name Store ID ltem List (array of pointers to Inventory Item objects, max of 512) ltem
Count (tracking how many items are currently stored in the array) .Constructors (initialize all
pointers in the array to NULL in addition to what\'s described below .Default constructor: set
data members to 0 (for integers), 0.0 (for float/double), or NULL (for pointers) as appropriate.
Also invoke this function to initialize a seed for the random generator srand (time (NULL), (to
be used later by Product class to genearte random values for Product ID. See Code Helper
section at the end of the lab specs.) .Non-default constructor: taking a string for store name, an
integer for store ID. Call srand as shown above Destructor: de-allocate dynamic memory in the
amay off pointers (up to Item Count elements) .Public member functions: BuildInventory: read a
text file containing Product records (one Product per line), dynamically allocate Product objects
and store the objects in the array ItemList (an array of Inventoryltem pointers). It should also
update Item Count as needed Shownventory: display all Products in the inventory. Output must
be properly formatted and aligned (usingfield with and floating data with 2 digits after decimal
point). Note that if you invoke the Display function using the pointers from the array only Invent
tem (base objec) information will be displayed. Extra work is needed to properly display
Products (derived objects) information ntory: display only defective Products Terminate: iterate
thru the array of pointers to write Product objects in the array to a text file in the same format as
they were read in. You may use a different file name for wniting .mutator cessors for store name,
store id, and item count

C++ Language -- Dynamic Memory -- There are 7 files in this project- a.pdf
C++ Language
** Dynamic Memory **
There are 7 files in this project, and they are down below. And I guess the professor wants us to
modify the set.cpp make sure the numbers are entered by the user to be set dynamically. If you
pay attention to the set.cpp I marked in bold a section that may be needed to be changed. I have
put all the codes down so that you can copy them to your computer to have an idea of how they
work together. Only that Set.cpp must be modified so the number of elements can be set
dynamically during the program's execution. And please can you be more specific about what
line of code needs to be replaced?
Here are the professor's instructions.
** Note: The goal of this assignment is to MODIFY the existing code. **
Implement a dynamically allocated version of the mathematical concept of a 'set'. First, examine
the provided library and driver (in main) for a statically allocated Set class. You may also want
to refresh your mathematical memory of the set concept before proceeding.
Now that you are familiar with how the Set class works, let's make it work better. Currently, the
user is limited to a certain maximum number of elements in their Set. Change it so the number of
elements can be set dynamically during the program's execution.
Extend the driver to test all the ADT's operations.
** Things to Consider **
1. If your set is implemented in dynamic memory:
1a. How do you access the members?
1b. How and when do you re-size the memory?
HERE are the CODE files:.
main.cpp
include <iostream>
#include <cctype>
#include "input.h"
#include "set.h"
using namespace std;
int main(void)
{
Set x, y, z;
bool quit;
long newone;
do
{
cout << "Enter a long integer: ";
cin >> newone;
if (x.ismember(newone))
{
cout << "You've already entered that!" << endl;
}
else

Manually determine the configuration of the priority queue (stored as a heap) created
by the following operations. Trace the following logic and define the output:
enqueue(7);
enqueue(17);
enqueue(2);
enqueue(5);
enqueue(22);
enqueue(19);
enqueue(6);
enqueue(11);
enqueue(13);
write the queue contents
dequeue and write front item
enqueue(15);
enqueue(8);
dequeue and write front item
dequeue and write front item
enqueue(24);
enqueue(14);
write the queue contents
Part 2
Then, verify the output by implementing the algorithm by rewriting the priority
queue demonstration program discussed in class. Files needed:
testPQueue.cpp pqType.h heap.cpp
Deliverables
• This cover sheet (with your names on it)
• Driver source code and output for verification program exectution.

CST 280 In-Class Practice – Week 13
Use this page as a worksheet to sketch the progression of the elements up to the first
split for the QuickSort algorithm. Use the middle array element as the split value:
15 34 99 42 11 41 66 23 55 93 48
Next, access the file quickSort.cpp from the course web page. Tailor the program
by entering the array values above in place of the integer values used for an in-class
demonstration. Be sure to adjust the index range to match the size of this array.
Remember that the parameters to the QuickSort algorithm are starting and ending index
values, not the size of the array.
Next, insert code to demonstrate the state of the array after the first split. This should
verify what you did by hand above. Insert the following code at various points within
the partition function to “see” the array at various stages of processing:
for (int i = start; i <= end; i++) // <== ADD
cout << set[i] << ' ';
cout << endl;
Insert the code at these positions:
int partition(int set[], int start, int end)
{
int pivotValue, pivotIndex, mid;
mid = (start + end) / 2;
swap(set[start], set[mid]);
pivotIndex = start;
pivotValue = set[start];
ç HERE
for (int scan = start + 1; scan <= end; scan++)
{
if (set[scan] < pivotValue)
{
pivotIndex++;
swap(set[pivotIndex], set[scan]);
}
ç HERE
}
swap(set[start], set[pivotIndex]);
ç HERE
return pivotIndex;
}
Finally, identify the line that matches what you concluded above.
Deliverables:
Deliver the following for this assignment:
• This work sheet with a sketch of the array first split
• Program source code with required change
• Program output demonstrating array configuration after first split .

Threads and Callbacks for Embedded Python
Python is a great choice to be customized plug-ins for existing applications. Extending existing applications with Python program is also practical. For large systems, multi-thread programming is ubiquitous along with asynchronous programming, such as event routing. This presentation focuses on dealing with threads and callbacks while embedding Python in other applications.
Develop an inventory management system for an electronics store. The .pdf
Develop an inventory management system for an electronics store. The inventory system should
have the following functionalities .BuildInventory: reada text file containing electronics products
information and store them in an array of pointers .Shownventory display all inventory items
.ShowDefectInventory: display inventory items that are defective Terminate: to save cument
inventory to a text file This lab assignment illustrates the following concepts: -Text file readings
and writings .Arrays of pointers and dynamic memory allocations with new and delete
Inheritance .C++ type casting: static cast Class Design You need at least three classes class
Inventory System: (minimum implementation specified below). This class stores Inyentoryltem
objects (which are in fact Inventory item base class pointers to derived Product objects and
member functions to manipulate those Product objects as shown below. .Private data members
Store Name Store ID ltem List (array of pointers to Inventory Item objects, max of 512) ltem
Count (tracking how many items are currently stored in the array) .Constructors (initialize all
pointers in the array to NULL in addition to what\'s described below .Default constructor: set
data members to 0 (for integers), 0.0 (for float/double), or NULL (for pointers) as appropriate.
Also invoke this function to initialize a seed for the random generator srand (time (NULL), (to
be used later by Product class to genearte random values for Product ID. See Code Helper
section at the end of the lab specs.) .Non-default constructor: taking a string for store name, an
integer for store ID. Call srand as shown above Destructor: de-allocate dynamic memory in the
amay off pointers (up to Item Count elements) .Public member functions: BuildInventory: read a
text file containing Product records (one Product per line), dynamically allocate Product objects
and store the objects in the array ItemList (an array of Inventoryltem pointers). It should also
update Item Count as needed Shownventory: display all Products in the inventory. Output must
be properly formatted and aligned (usingfield with and floating data with 2 digits after decimal
point). Note that if you invoke the Display function using the pointers from the array only Invent
tem (base objec) information will be displayed. Extra work is needed to properly display
Products (derived objects) information ntory: display only defective Products Terminate: iterate
thru the array of pointers to write Product objects in the array to a text file in the same format as
they were read in. You may use a different file name for wniting .mutator cessors for store name,
store id, and item count

C++ Language -- Dynamic Memory -- There are 7 files in this project- a.pdf
C++ Language
** Dynamic Memory **
There are 7 files in this project, and they are down below. And I guess the professor wants us to
modify the set.cpp make sure the numbers are entered by the user to be set dynamically. If you
pay attention to the set.cpp I marked in bold a section that may be needed to be changed. I have
put all the codes down so that you can copy them to your computer to have an idea of how they
work together. Only that Set.cpp must be modified so the number of elements can be set
dynamically during the program's execution. And please can you be more specific about what
line of code needs to be replaced?
Here are the professor's instructions.
** Note: The goal of this assignment is to MODIFY the existing code. **
Implement a dynamically allocated version of the mathematical concept of a 'set'. First, examine
the provided library and driver (in main) for a statically allocated Set class. You may also want
to refresh your mathematical memory of the set concept before proceeding.
Now that you are familiar with how the Set class works, let's make it work better. Currently, the
user is limited to a certain maximum number of elements in their Set. Change it so the number of
elements can be set dynamically during the program's execution.
Extend the driver to test all the ADT's operations.
** Things to Consider **
1. If your set is implemented in dynamic memory:
1a. How do you access the members?
1b. How and when do you re-size the memory?
HERE are the CODE files:.
main.cpp
include <iostream>
#include <cctype>
#include "input.h"
#include "set.h"
using namespace std;
int main(void)
{
Set x, y, z;
bool quit;
long newone;
do
{
cout << "Enter a long integer: ";
cin >> newone;
if (x.ismember(newone))
{
cout << "You've already entered that!" << endl;
}
else
{
x.add_elem(newone);
cout << "Value added to list!" << endl;
}
quit = toupper(get_in_set("YyNn", "Would you like to enter more? ")) == 'N';
} while (!quit && !x.full());
cout << "Overall, you entered: " << endl;
x.output(cout);
cout << endl;
cout << "Please enter a set of long integers: ";
x.input(cin);
cout << endl << "You entered:\n";
x.output(cout);
cout << endl;
cout << "Please enter another set of long integers: ";
y.input(cin);
cout << endl << "You entered:\n";
y.output(cout);
cout << endl;
cout << "The union of the two sets is:\n";
z = x;
z.union_with(y);
z.output(cout);
cout << endl;
cout << "The intersection of the two sets is:\n";
z = x;
z.intersection(y);
z.output(cout);
cout << endl;
return 0;
}
input.cpp
#include "input.h"
#include <iostream>
#include <cstring>
#include <cctype>
using namespace std;
// Boundaries are assumed to be solid -- low <= value <= high.
// Enum to say which end is to be bounded...
//
// enum BoundType { Low, High, Both };
// Bounded entry function for long integers...
//

long high,
const char prompt[] /* = "Enter bounded value: " */,
BoundType which_end /* = Both */)

Guessing or knowing the initial TCP sequence number (ISN) that a serve.pdf
Guessing or knowing the initial TCP sequence number (ISN) that a server will choose enables an
attacker to establish a TCP connection. Please discuss if the following solutions are secure (to
prevent hijacking etc.) against off-path attackers and why. [x] denotes truncation of x to the 32
32
least significant bits. K is a (permanent) secret key stored locally and only known to the server.
H represents a secure hash function (e.g., SHA256) and its algorithm is publicly known. Also
note that || means concatenation and current timestamp is represented as UNIX timestamp. You
can assume that 4 tuple information (source / destination IP and port) are known to the attacker.
(1) Server selects ISN as ISN = [H(K)] .
32
(2) Server computes ISN as follows: ISN = [H(source IP address XOR destination IP address
XOR current timestamp XOR K)] .
32
(3) Server computes ISN as ISN = [H(source IP address || destination IP address || source port
number || destination port number || current timestamp)] .
32
(4) Server selects ISN using a standard (i.e., publicly-known) pseudo random generator with K
as a seed.
(5) Server selects ISN as ISN = [AES ECB(K, counter)] , where the counter is continuous from
32
the previous communication session..

Given an IntNode struct and the operating functions for a linked list-.pdf
Given an IntNode struct and the operating functions for a linked list, complete the following
functions to extend the functionality of the linked list:
IntNode* IntNode_GetNth(IntNode* firstNode, int n)- Return a pointer to the nth node of the list
starting at firstNode.
void IntNode_PrintList(IntNode* firstNode) - Call IntNode_PrintNodeData() to output values of
the list starting at firstNode. Do not add extra space characters in between values.
int IntNode_SumList(IntNode* firstNode) - Return the sum of the values of all nodes starting at
firstNode.
Note: The code for IntNode_Create() provided here differs from the code shown in the book.
The given main() performs various actions to test IntNode_GetNth(), IntNode_PrintList(), and
IntNode_SumList().
main() reads 5 integers from a user:
The number of nodes to be added to a new list
The value of the first node of the list
An increment between the values of two consecutive nodes.
A value of a new node
The position of a node after which the new node will be added, with 1 indicating the first node
Ex: If the input is:
the output is:

June 3, 2024 Anti-Semitism Letter Sent to MIT President Kornbluth and MIT Cor...
Letter from the Congress of the United States regarding Anti-Semitism sent June 3rd to MIT President Sally Kornbluth, MIT Corp Chair, Mark Gorenberg
Dear Dr. Kornbluth and Mr. Gorenberg,
The US House of Representatives is deeply concerned by ongoing and pervasive acts of antisemitic
harassment and intimidation at the Massachusetts Institute of Technology (MIT). Failing to act decisively to ensure a safe learning environment for all students would be a grave dereliction of your responsibilities as President of MIT and Chair of the MIT Corporation.
This Congress will not stand idly by and allow an environment hostile to Jewish students to persist. The House believes that your institution is in violation of Title VI of the Civil Rights Act, and the inability or
unwillingness to rectify this violation through action requires accountability.
Postsecondary education is a unique opportunity for students to learn and have their ideas and beliefs challenged. However, universities receiving hundreds of millions of federal funds annually have denied
students that opportunity and have been hijacked to become venues for the promotion of terrorism, antisemitic harassment and intimidation, unlawful encampments, and in some cases, assaults and riots.
The House of Representatives will not countenance the use of federal funds to indoctrinate students into hateful, antisemitic, anti-American supporters of terrorism. Investigations into campus antisemitism by the Committee on Education and the Workforce and the Committee on Ways and Means have been expanded into a Congress-wide probe across all relevant jurisdictions to address this national crisis. The undersigned Committees will conduct oversight into the use of federal funds at MIT and its learning environment under authorities granted to each Committee.
• The Committee on Education and the Workforce has been investigating your institution since December 7, 2023. The Committee has broad jurisdiction over postsecondary education, including its compliance with Title VI of the Civil Rights Act, campus safety concerns over disruptions to the learning environment, and the awarding of federal student aid under the Higher Education Act.
• The Committee on Oversight and Accountability is investigating the sources of funding and other support flowing to groups espousing pro-Hamas propaganda and engaged in antisemitic harassment and intimidation of students. The Committee on Oversight and Accountability is the principal oversight committee of the US House of Representatives and has broad authority to investigate “any matter” at “any time” under House Rule X.
• The Committee on Ways and Means has been investigating several universities since November 15, 2023, when the Committee held a hearing entitled From Ivory Towers to Dark Corners: Investigating the Nexus Between Antisemitism, Tax-Exempt Universities, and Terror Financing. The Committee followed the hearing with letters to those institutions on January 10, 202
