Convert that number of cents to the equivalent number of quarters, dimes, nickels, and pennies. Then output the maximum number of quarters that will fit the amount, then the maximum number of dimes that will fit into what then remains, and so on. If the amount entered is negative, write an error message and quit. Amounts greater than 100 are OK (the user will get many quarters.) Use extended assembly instructions and exception handler services.
Answer:
Explanation:
The following code is written in python and divides the amount of cents enterred in as an input into the correct amount of quarters, dimes, nickels and pennies. Finally, printing out all the values.
import math
#First we need to define the value of each coin
penny = 1

quarter = 25
#Here we define the variables to hold the max number of each coin
quarters = 0
dimes = 0
nickels = 0
pennys = 0
cents = int(input("Please enter an amount of money you have in cents: "))
if cents > 0 and cents <= 100:

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.
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.

Your company has been assigned the 194.10.0.0/24 network for use at one of its sites. You need to calculate a subnet mask that will accommodate 60 hosts per subnet while maximizing the number of available subnets. What subnet mask will you use in CIDR notation?
To accommodate 60 hosts per subnet while maximizing the number of available subnets, we need to use a subnet mask that provides enough host bits and subnet bits.
How to calculateTo calculate the subnet mask, we determine the number of host bits required to accommodate 60 hosts: 2^6 = 64. Therefore, we need 6 host bits.
Subsequently, we determine the optimal quantity of subnet bits needed to increase the quantity of accessible subnets: the formula 2^n >= the amount of subnets is used. To account for multiple subnets, the value of n is set to 2, resulting in a total of 4 subnets.
Therefore, we need 2 subnet bits.
Combining the host bits (6) and subnet bits (2), we get a subnet mask of /28 in CIDR notation.
