The primary purpose of a use case diagram is
Select one:
a. to uncover additional details such as attributes and methods of a class
b. to show the users interaction with the system
c. model the interaction between the system and its environment
Answers
The primary purpose of a use case diagram is to model the interaction between the system and its environment. Use case diagrams depict the functionality of a system from the user's perspective, focusing on the system's behavior as it responds to requests from the users or other external actors. They show the different use cases or scenarios that users can perform with the system and the actors that participate in these interactions. Use case diagrams are often used in requirements analysis and software design to help clarify and communicate the system's purpose and behavior. Option (c) correctly explains the primary purpose of a use case diagram.
Answer:
b. to show the users interaction with the system
Explanation:
A use case diagram is a type of UML diagram that shows the interactions between a system and the actors that use it. It is used to model the behavior of a system from the perspective of the users. A use case diagram does not show the internal details of the system, but only the interactions between the system and the actors.
The other options are incorrect.
Option a is incorrect because a use case diagram does not show the attributes and methods of a class. Option c is incorrect because a use case diagram does not model the interaction between the system and its environment.xamine the following output:

In this c++ assignment, add an undo feature to a list of strings.
Here's a working class called Stringlist that implements a simple string list as a dynamic array. Stringlist_test.cpp has tests for all the methods in Stringlist.
Stringlist has one unimplemented method:
// Undoes the last operation that modified the list. Returns true if a
// change was undone, false otherwise.
//
bool undo()
{
cout << "Stringlist::undo: not yet implemented\n";
return false;
}
Your job is to implement undo, thus making Stringlist an undoable list.
Your implementation must follow these rules:
Do not delete any methods, or change the signatures of any methods, in Stringlist. You can change the implementation of existing methods if necessary. But they should still work the same way: your finished version of Stringlist with undo implement must still pass all the tests in Stringlist_test.cpp.
You can add other helper methods (public or private), functions, and classes/structs to Stringlist.h if you need them.
You must implement undo() using a private stack that is accessible only inside the Stringlist class. Implement the stack yourself as a linked list. Do not use arrays, vectors, or any other data structure for your stack.
Do not use any other #includes or #pragmas in Stringlist.h other than the ones already there.
When it's done, you'll be able to write code like this:
#include "Stringlist.h"
#include
using namespace std;
int main() {
Stringlist lst;
cout << lst << endl; // {}
lst.insert_back("one");
lst.insert_back("two");
lst.insert_back("three");
cout << lst << endl; // {"one", "two", "three"}
lst.undo();
cout << lst << endl; // {"one", "two"}
lst.undo();
cout << lst << endl; // {"one"}
lst.undo();
cout << lst << endl; // {}
}
Designing the Undo Stack
As mentioned above, you must implement undo() using at least one private stack implemented as a linked list inside the Stringlist class. You can modify Stringlist only as described at the start of this assignment.
examples of how specific methods should work.
Undoing insert_before
In code:
// lst == {"dog", "cat", "tree"}
lst.insert_before(3, "hat");
// lst == {"dog", "cat", "tree", "hat"}
lst.undo();
// lst == {"dog", "cat", "tree"}
lst.insert_before(1, "shoe");
// lst == {"dog", "shoe", "cat", "tree"}
lst.undo();
// lst == {"dog", "cat", "tree"}
Undoing set
For set, suppose that lst is {"yellow", "green", "red", "orange"}, and so lst.get(2) returns "red". If you call lst.set(2, "cow"), then you should push the operation set location 2 to "red" onto the undo stack, and then over-write location 2 with "cow".
In code:
// lst == {"yellow", "green", "red", "orange"}
lst.set(2, "cow");
// lst == {"yellow", "green", "cow", "orange"}
lst.undo();
// lst == {"yellow", "green", "red", "orange"}
Undoing remove_at
For remove_at
In code:
// lst == {"dog", "cat", "tree"}
lst.remove_at(1);
// lst == {"dog", "tree"}
lst.undo();
// lst == {"dog", "cat", "tree"}
Undoing operator=
For operator=,
In code:
// lst1 == {"dog", "cat", "tree"}
// lst2 == {"yellow", "green", "red", "orange"}
lst1 = lst2;
// lst1 == {"yellow", "green", "red", "orange"}
// lst2 == {"yellow", "green", "red", "orange"}
lst1.undo();
// lst1 == {"dog", "cat", "tree"}
// lst2 == {"yellow", "green", "red", "orange"}
As this shows, when you undo operator=, the entire list of strings is restored in one call to undo().
Important notes:
If lst1 and lst2 are different objects, then when lst2 is assigned to lst1 just the underlying string array of lst2 is copied to lst1. The lst1 undo stack is updated so that it can undo the assignment. The undo stack of lst2 is not copied, and lst2 is not modified in any away.
Self-assignment is when you assign a list to itself, e.g. lst1 = lst1;. In this case, nothing happens to lst1. Both its string data and undo stack are left as-is.
Undoing remove_all
For remove_all,
In code:
// lst == {"dog", "cat", "tree"}
lst.remove_all();
// lst == {}
lst.undo();
// lst == {"dog", "cat", "tree"}
Note that it should work the same way when lst is empty:
// lst == {}
lst.remove_all();
// lst == {}
lst.undo();
// lst == {}
Undoing Other Methods
undo() should undoall the other methods in Stringlist that are marked as "undoable" in the source code comments.
As mentioned above, undo() is not undoable. There is no "re-do" feature in this assignment.
Each method in Stringlist.h marked "undoable" should work correctly with undo(). This also includes the correct behaviour for the Stringlist copy constructor (which should not copy the undo stack).
The markers tests should run correctly, including with no memory leaks according to valgrind.
Answers
To implement the undo feature in the Stringlist class, you will need to modify the existing class and add a private stack implemented as a linked list. Here are the steps to follow:
How to write the program code1. In the Stringlist class in Stringlist.h, add a private struct called `UndoNode` to represent each node in the undo stack. Each node should store the necessary information to undo an operation (e.g., the method name, the arguments, and any other relevant data).
```cpp
private:
struct UndoNode {
std::string method; // The method name
// Add other necessary data for the specific method being undone
// ...
UndoNode* next; // Pointer to the next node in the stack
UndoNode(const std::string& m) : method(m), next(nullptr) {}
};
```
2. Add a private member variable `undoStack` of type `UndoNode*` to the Stringlist class to keep track of the undo stack.
```cpp
private:
// Other private member variables
UndoNode* undoStack;
```
3. Modify the undoable methods in the Stringlist class to push the necessary information onto the undo stack before performing the operation. For example, in the `insert_before` method:
```cpp
void insert_before(size_t index, const std::string& str) {
// Push the operation onto the undo stack
UndoNode* undoNode = new UndoNode("insert_before");
// Add necessary data to the undoNode (e.g., index and str)
// ...
// Perform the actual operation
// ...
// Add the undoNode to the top of the stack
undoNode->next = undoStack;
undoStack = undoNode;
}
```
4. Implement the `undo` method to pop the top node from the undo stack and perform the undo operation based on the stored information. You will need to handle each operation individually in the `undo` method.
```cpp
bool undo() {
if (undoStack == nullptr) {
std::cout << "Undo stack is empty." << std::endl;
return false;
}
UndoNode* undoNode = undoStack;
undoStack = undoStack->next;
// Perform the undo operation based on the stored information in undoNode
if (undoNode->method == "insert_before") {
// Undo the insert_before operation
// ...
} else if (undoNode->method == "set") {
// Undo the set operation
// ...
}
// Handle other operations...
delete undoNode;
return true;
}
```
Remember to handle memory deallocation appropriately and update other methods marked as "undoable" accordingly.

a. Write code to implement the above class structure. Note the following additional information:
Account class: Create a custom constructor which accepts parameters for all attributes. The withdraw method should check the balance and return true if the withdrawal is successful.
SavingsAccount class: Create a custom constructor which accepts parameters for all attributes.
CurrentAccount class: Create a custom constructor which accepts parameters for all attributes. The withdraw method overrides the same method in the super class. It returns true if the withdrawal amount is less than the balance plus the limit.
Customer class: Create a custom constructor which accepts parameters for name, address and id.
b. Driver class:
Write code to create a new Customer object, using any values for name, address and id. Create a new SavingsAccount object, using any values for number, balance and rate. Set the SavingsAccount object as the Customer’s Savings account. Create a new CurrentAccount object, using any values for number, balance and limit. Set the CurrentAccount object as the Customer’s Current account.
Prompt the user to enter an amount to deposit to the Savings account and deposit the amount to the customer’s Savings account.
Prompt the user to enter an amount to withdraw from the Current account and withdraw the amount from the customer’s Current account. If the withdraw method is successful print a success message, otherwise print an error.
Finally print a statement of the customer accounts using methods of the Customer object. Output from the program should be similar to the following:
Enter amount to withdraw from current account:

672.2The internet 24A buffer is 2MiB in size. The lower limit of the buffer is set at 200KiB and the higher limit is set at 1.8MiB.Data is being streamed at 1.5Mbps and the media player is taking data at the rate 600kbps.You may assume a megabit is 1048576bits and a kilobit is 1024bits.a)Explain why the buffer is needed.[2]b)i)Calculate the amount of data stored in the buffer after 2 seconds of streaming and playback.You may assume that the buffer already contains 200KiB of data.[4]ii)By using different time values (such as 4 secs, 6 secs, 8 secs, and so on) determine how long it will take before the buffer reaches its higher limit (1.8MiB).[5]c)Describe how the problem calculated in part b) ii) can be overcome so that a 30-minute video can be watched without frequent pausing of playback
Answers
a) The buffer is needed to ensure smooth playback of streamed media by storing a certain amount of data in advance. This is done to prevent interruptions due to network congestion or variations in the streaming rate.
How to calculate the datab) i) The amount of data streamed in 2 seconds is (1.5Mbps * 2s) = 3MB. The amount of data played back in 2 seconds is (600kbps * 2s) = 150KB. Therefore, the amount of data stored in the buffer after 2 seconds is (3MB - 150KB - 200KiB) = 2.6MB.
ii) To determine how long it will take before the buffer reaches its higher limit of 1.8MiB, we can use the following formula:
Time to reach limit = (higher limit - lower limit - current buffer size) / streaming rate
= (1.8MiB - 200KiB - 2MiB) / 1.5Mbps
= 8 seconds
Therefore, it will take 8 seconds for the buffer to reach its higher limit.
c) To overcome the problem of frequent pausing of playback, a larger buffer can be used. This will allow more data to be stored in advance, reducing the impact of network congestion or variations in the streaming rate.'
Additionally, adaptive bitrate streaming can be used, where the streaming rate is dynamically adjusted based on the available network bandwidth, to ensure a more consistent streaming experience. Finally, a content delivery network (CDN) can be used to deliver the media from servers located closer to the viewer, reducing the impact of network latency and improving overall streaming performance.

(1 point) (c) if yes, give one of the above execution sequences that would lead to dbz. (2 points) (d) for the above execution sequence specify the input values that would cause dbz. (2 points)
Answers
The values of c₁, c₂, and c₃ create these distinct scenarios. If c₁ is correct, only the first case will prevail regardless of the values of c₂ and c₃.
There are four scenarios in which c₁ is false: (c₂ = T, c₃ = T), (c₂ = F, c₃ = T), and (c₂ = F, c₃ = F). The vulnerability occurs in the final scenario.
The different possible execution sequence are:(i) 16, 17, 18, 19, 31, 32, 33, 34
(ii) 16,17, 20, 21, 27, 31, 32, 33, 34
(iii) 16, 17, 20, 21, 27, 28, 31, 32, 33, 34
(iv) 16, 17, 20, 21, 22, 23, 24, 27, 28
(v) 16, 20, 21, 22, 27,31 , 32, 33, 34
(vi) 16, 17, 20, 21, 22, 23, 24, 27, 28, 31, 32, 33, 34
(a): Yes, the given code may contain the DBZ (division by zero) vulnerability.
(b): The vulnerabilities sequence is as follows: 16, 17, 20,21, 22, 23, 24, 27 ,28).
(c): c₁ =false, c₂ =true, c₃ =true, a=8 and b=2, and one of the input values that results in the CBZ are outlined in (b).
Vulnerability of the divide by zero :The product divides a value by zero. This flaw typically arises when the product receives an unexpected value or an error that is not properly detected. When calculating physical dimensions like size, length, width, and height, it frequently occurs.
What exactly is a zero-day flaw?A vulnerability in a system or device that has been discovered but has not yet been patched is known as a zero-day vulnerability. A zero-day exploit is one that targets a zero-day vulnerability.
