Accessing an object through a pointer?

Question

C++ / C#

I can't figure out why the error is popping up. It is necessary to create objects through the heap and then assign them to the variable x with the value n ( n is the number of the object).
PS: Help I'm dumb...

#include <iostream>
using namespace std;


class Object
{
public:
  int x = 0;
};


int main(int nArg, char* pszArgs[])
{
  Object* objects = new Object[100];
  Object* objaddr;
  for (int n = 0; n < 50; n++)
  {
    objaddr = objects + (sizeof(Object)*n);
    objaddr->x = n;
  }
  return 0;

}

Answer 1

Why not objects[n].x = n
