Question

Please answer the following question in C++.

(a) Define and implement a Person class, which has data members as described below: Name . Age (b) Next, you will create an STL deque of Person objects as follows: . Call the deque StoreDeque. Initialize the deque with about 5 Person objects. » Create a loop with discrete time steps t-1,2, M. » At each time step, either 0 or 1 Person object gets added to the back of Store- Deque . At each time step, either 0 or 1 Person object gets taken off the front of Store- Deque (c) Some notes: . An STL deque is a double-ended queue . You want to utilize the rand ) function, to choose at random either 0 or 1 in the above code. You want to check the size of the deque at each time step.

#include <iostream>
#include <string.h>
#include <unistd.h>   //fo sleep func

#include <bits/stdc++.h>
using namespace std;

class Person       //person class
{
public:
char name[20];
int age;
  
Person()       //default constructor
{
strcpy(name,"ABC");
age = 73;
}
};

int main()
{
int m;           //user input
deque <Person> StoreDeque;   //deque
  
Person p1;
strcpy(p1.name,"A");
p1.age = 12;
  
Person p2;
strcpy(p2.name,"B");
p2.age = 14;
  
Person p3;

p3.age = 16;
  
Person p4;
strcpy(p4.name,"D");
p4.age = 62;
  
Person p5;

StoreDeque.push_back(p1);       //initial insertion
