Suppose the variable my_register is declared to be of type Cash Register, which is an object. Suppose further that the CashRegister object has a member function named clear(). If the special parameter variable this is used within the member function clear, exactly how would you describe the meaning of that variable when the following statement is executed? my_register.clear() this is a pointer to the clear() member function. this is a pointer to the my_register object. this is a pointer to the generic CashRegister data type. this is a pointer to the parameter variables for the clear() member function.
