Objective: Experiment with Lists, Stacks, and Queues:
Simulate an OS task manager
Assignment:
Using the startup code, implement the following:
1-Create List L1 of 10 elements (task IDs), e.g. L1 = 1, 2, 3, 4, 5, 6, 7, 8, 9, 10;
2-Insert a new list element in between (at every other element), such as: 1,100, 2,200, 3,300, 4,400, ... 10,1000;
Simulate a new CPU core assignment:
3-Create another List L2, and extract the newly inserted elements into this new list L2
i.e. L1 should go back to the original list: L1 = 1, 2, 3, 4, 5, 6, 7, 8, 9, 10
L2 should be: 100, 200, 300, 400, 500, 600, 700, 800, 900, 1000
Start executing:
4-Create a Queue Q1 by extracting L1, and inserting L2 elements: i.e. Q should start with: 1,2,3, ... 10, and (10, 20 ... 100) will be inserted
Q1=1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 100, 200, 300, 400, 500, 600, 700, 800, 900, 1000
Label tasks as finished with the possibility of revisiting a task, such as:
5-Create a Stack S1 which by deleting the elements of Q1 and inserting them in L1
6-Pop out all elements of the Stack, i.e. should end up with an empty stack
Extra credit: Simulate a re-executed task, i.e. Pop out a task out of the Stack and reinsert, this simulate a failed task.
7-Verify the functionality and capture the results in a report form.

int main()
{
int i;
const int N = 10;
List<int> L1;
Stack<int> S1;
Queue<int> Q1;
List<int>::iterator node; //Variable to keep track of the position as we traverse
// List Section example:
//Q1: Create List L1 of 10 elements, e.g. L1 = 1, 2, 3, 4, 5, 6, 7, 8, 9, 10;
// create the list array as a starting point:
for (i = N; i > 0; --i)
{
L1.push_front(i);
}
// show L1 with an iterator
cout << "List L1 is:" << endl;
for (auto it = L1.begin(); it != L1.end(); ++it)
{
cout << *it << ' ';
}
// Stack Section example:
//
// Stack to be created per the above assignment requirment
cout << "\nStack S1 is:" << endl;;
for (i = N - 1; i >= 0; --i)
{
S1.push(i);
cout << S1.top() << " " << endl;
}
while (!S1.isEmpty())
{
cout << S1.top() << endl;
S1.pop(i);
}
// Queue section, to be created per the above assignment requirment
//
//
return 0;
