11.7.3.assign the address of a public member of an object to a pointer and then access that member by using the pointer

#include <iostream>

using namespace std;

   

class cl {

public:

  int i;

  cl(int j) { i=j; }

};

   

int main()

{

  cl ob(1);

  int *p;

   

  p = &ob.i; // get address of ob.i

   

  cout << *p; // access ob.i via p

   

  return 0;

}
