You have to create a C++ program for office task management using Stack data structure implemented with linked list. The objective is to develop a computer program that allows users to efficiently handle their tasks as a Last-In, First-Out (LIFO) data structure.. The program should allow office employees to add, remove and display tasks in a Stack.
Requirements:
You are required to implement a stack data structure using a singly linked list. The stack should be used to manage a collection of tasks.
Implement the following operations on the output console:
1- Push a Task onto the Stack: Users should have the ability to push a new task onto the stack. They should provide the following details:
2- Pop a Task from the Stack: Users should be able to pop and remove the task at the top of the stack. T
3- Display the Top Task: Users can view the details of the task that is currently at the top of the stack
4- Display the Entire Stack: The user should be able to view the entire list of tasks, including the task name, task ID, description, and due date.
Stack should be implemented using a linked list data structure, with each node representing a single task in the tasks list. Each node should contain the task name, task ID, description, and due date..
#include<iostream>
#include<conio.h>
using namespace std;
class Task
{
private:
int taskID;
string taskName, description, dueDate;
Task *next;
public:
void setTaskID(int id)

string getDescription()
{

}
void setDueDate(string date)
{
dueDate = date;
}
string getDueDate()
{
return dueDate;
}
void setNext(Task *nextNode)
{
next = nextNode;
}
Task* getNext()
{

}
};
class TaskStack
{

public:

{

}

head = head -> getNext();

}
