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; }
