C++ Vector of Pointers help

[firthy15]

#include<iostream>
using namespace std;
#include <vector>  

class Object{
      public:
             Object(int, int);
             void printDetails();
      private:
              int x;
              int y;
              };
      
Object::Object( int xnum, int ynum)
{
            x = xnum;
            y = ynum;
}


void Object::printDetails()
{
     cout << x << " , " << y;
}

int main()
{
    vector<Object*>lolvector;
    
    for ( int z = 0; z != -1; z++) //starting for loop
    {
        int x, y;
        cout << "x = ?"; //reading in the variables
        cin >> x;
        cout << "y = ?";
        cin >> y;
        
        Object *intptr;
        intptr = new Object(x,y);
        lolvector[z] = intptr;
    }

}

Right so. Im trying to take input from the keyboard and insert it into objects to which then i am filling a vector with pointers to these objects. Can anyone see anything wrong with this. I ask as i cant figure out how to even test it. I thought it would be along the lines of :

lolvector[1].printDetails();

But it gives me errors and i cannot find any information on it in my notes so any help would be appreciated.

You're adding the objects into the vector in the wrong way. You use the push_back() function, ie:

lolvector.push_back(intptr);

And the container doesn't know what it's holding, so you need to do some type of cast (static casting probably). Look it up.

right i thought i had to use something along the line of pushback and i do beleive i know static casting etc, forcing a variable to be of a certain type right?

What do i need it for in relation to this?
