Question

Which syntax doesn’t execute/is false when executed?

(a) if(&object != this)

(b) if(&function !=object)

(c) this.if(!this)

(d) this.function(!this)

The question was posed to me in my homework.

I would like to ask this question from This Pointer topic in chapter Assigning Object, Pointer to Objects, Passing and Returning Object of Object Oriented Programming

Answer 1

The correct option is (a) if(&object != this)

Explanation: The condition becomes false when executed and hence doesn’t executes. This is the case where this pointer can guard itself from the self-reference. Here if the address of the object doesn’t match with this pointer that means the object doesn’t refer itself.
