Question
Which among the following is true?a) this pointer is passed implicitly when member functions are calledb) this pointer is passed explicitly when member functions are calledc) this pointer is passed with help of pointer member functions are calledd) this pointer is passed with help of void pointer member functions are called
Solution
The correct answer is a) this pointer is passed implicitly when member functions are called.
Here's why:
In C++, when a member function is called, the 'this' pointer is passed implicitly. The 'this' pointer is a special pointer that points to the object which invokes the member function. It is not passed explicitly by the programmer, but rather, it is done automatically by the compiler.
The other options b), c), and d) are incorrect because the 'this' pointer is not passed explicitly, nor is it passed with the help of pointer member functions or void pointer member functions.
