Question

Where in the parameter list is the implicit *this is added?

(a) Right most parameter

(b) Anywhere in parameter list

(c) Left most parameter

(d) Not added to parameter list

I had been asked this question during an internship interview.

I would like to ask this question from Member Operator Function topic in chapter Member Functions & its Types of Object Oriented Programming

Answer 1

Correct choice is (c) Left most parameter

To explain I would say: The left operand is passed implicitly by the compiler to the member function. But this is done, when the compiler adds the calling object as *this to the parameter list. It is always added as the left most parameter, i.e. the first parameter of the function.
