You can use the address-of operator (&). This denotes an address in memory. You can say "cout << &obj;" to get the address of an object. You can also store it to a pointer, and then get the address that way. Here is a complete example of using a pointer to get an object's address, and execute one of the object's functions:
#include <iostream>
using namespace std;
int main() {
class boy {
public:
void sayhello(){
cout << "hi" << endl;
}
};
boy one;
one.sayhello();
cout << &one << endl;
boy *ptr;
ptr = &one;
cout << ptr << endl;
ptr->sayhello();
return 0;
}
