C++ this pointer MCQ: Multiple Choice Questions and Answers on C++ this pointer

1 / 26

Which is the correct interpretation of the member function call from an object, object.function(value);

function(&object, &value)

function(&object,value)

object(&function,value)

object.function(&this, value)

2 / 26

What is the significance of using the const qualifier in the following member function declaration:

int get() const;

It makes the function a friend of the class.

It makes the member function static.

It specifies that the function returns a constant value.

It indicates that the function does not modify the object's data members.

3 / 26

4 / 26

In a const member function, the type of the this pointer is treated as:

5 / 26

Which modifier affects this pointer?

only const

only volatile

const and volatile both

None of the above

6 / 26

In which type of member function is the "this pointer" treated as a pointer to a constant object?

Static member functions

Friend functions

Const member functions

Virtual member functions

7 / 26

How is the this pointer affected when a non-static member function is declared as volatile?

It becomes a constant pointer to a volatile object.

It becomes a volatile pointer to a constant object.

It remains unaffected.

It becomes a volatile pointer to a constant object.

8 / 26

Earlier implementations of C++ ___________________

Never allowed assignment to this pointer

Allowed assignments to this pointer

None of the above

9 / 26

This pointer can be used directly to ___________

To manipulate self-referential data structures

To manipulate any reference to pointers to member functions

To manipulate class references

To manipulate and disable any use of pointers

10 / 26

When is the this pointer required to be used explicitly in a member function?

When there is a locally declared object with the same name as the member object.

When calling a base class member from a derived class.

All of the above

None of these

11 / 26

Which is the pointer which denotes the object calling the member function?

Variable pointer

Null pointer

This pointer

None of the above

12 / 26

Which statement is true?

The type of this pointer in a member function of a class X is X*

If the member function is declared const, the type of this is const X*

If the member function is declared volatile, the type of this is volatile X*

All of the above

13 / 26

Whenever non-static member functions are called _______________

Address is specified as return type of the function

Address of the object is passed explicitly as an argument

Address of the object is passed implicitly as an argument

Address is specified globally so that the address is not used again

14 / 26

Which among the following is true?

This pointer can be used to guard against any kind of reference

This pointer can be used to guard against self-reference

This pointer can be used to guard from other pointers

This pointer can be used to guard from parameter referencing

15 / 26

Which statement is true for this pointer?

Friend functions do not have “this pointer”, because friends are not members of a class

static member function must have this pointer

this pointer always modify

None of the above

16 / 26

In a member function, if a local variable has the same name as a data member, how can you refer to the data member using the this pointer?

Use variableName

Use this->variableName

Use class::variableName

It is not possible to refer to the data member in this situation.

17 / 26

Which statement is true?

“this” keyword is a prvalue expression

“this pointer” isn’t part of the object itself

Nonstatic member functions of a class, struct, or union type only has the this pointer.

All of the above

18 / 26

The address of the object _________________

Can’t be accessed from inside the function

Can’t be accessed in the program

Is available inside the non-static member function using this pointer

None of the above

19 / 26

The this pointers _____________________

Are modifiable

Are non-modifiable

Can be assigned any value

None of the above

20 / 26

Which among the following is true?

this pointer is passed implicitly when member functions are called?

this pointer is passed explicitly when member functions are called

this pointer is passed with help of pointer member functions are called

this pointer is passed with help of void pointer member functions are called

21 / 26

What happens if you attempt to modify a data member using the this pointer in a const member function?

It is allowed, but the data member becomes const.

It is allowed, and the data member is modified.

It triggers a runtime error.

It results in a compilation error.

22 / 26

What is the purpose of the "this pointer" in C++?

It points to the class constructor.

It points to the current instance of the class.

It is used to call static member functions.

It represents the object being declared.

23 / 26

What does the this pointer allow you to access in a member function?

Only public members of the class.

Static members of the class.

Private members of the class

All members of the class.

24 / 26

if (&Object != this)

if (Object != this)

if (&Object != *this)

None of the above

25 / 26

The this pointer is accessible __________________

Within the member functions with zero arguments

Only within non-static functions

Within all the member functions of the class

None of the above

26 / 26

The result of sizeof() function __________________

Includes space reserved for this pointer
