C++ Tutorial : This pointer and static members

This Pointer

The keyword this represents a pointer to the object whose member function is being executed. It is a pointer to the object itself.
One of its uses can be to check if a parameter passed to a member function is the object itself. For example,

// this
#include <iostream>
using namespace std;
class CDummy {
public:
int isitme (CDummy& param);
};
int CDummy::isitme (CDummy& param)
{
if (&param == this) return true;
else return false;
}
int main () {
CDummy a;
CDummy* b = &a;
if ( b->isitme(a) )
cout << "yes, &a is b";
return 0;
}
