OOP Types of Constructors Quiz Online Practice Test

1. Generally, how many types of constructors are there in most programming languages?

2. When assigning one object to another, which constructor is invoked?

Default

Parameterized

Copy

Direct assignment is used

3. Why must objects be passed by reference in a copy constructor?

Constructor is not called with pass by reference

Constructor is only invoked with pass by reference

It provides the address of the new constructor to be created

It provides the address of the existing object for copying

4. Which specifier is specifically designated for constructor functions?

Public

Protected

Implicit

Explicit

5. Which statement accurately describes default constructors?

Programmers cannot define a default constructor.

A constructor with default parameters is not the same as a default constructor.

A default constructor can be called explicitly.

Default constructors are called implicitly and cannot be called explicitly.

6. Which constructor type inherently lacks a return type?

Default

Parameterized

Copy

Constructors don’t have a return type

7. What is the purpose of static constructors?

To initialize the static members of class

To initialize all the members with static value

To delete the static members when not required

To clear all the static members initialized value

8. At what point and how often is a static constructor called?

Created at the time of object destruction

Called the first time an object is created and only once

Called the first time an object is created and with every new object creation

Called whenever an object goes out of scope

9. Which statement accurately describes a static constructor?

Static constructors are invoked with each new object

Static constructors always initialize data members to zero

Static constructors cannot have parameters

Static constructors can also initialize non-static members

10. What is the default initialization of data members by a default constructor?

All numeric members with garbage values and strings with random values

All numeric members with garbage values and strings with null

All numeric members with zero and strings with random values

All numeric members with zero and strings with null

11. At what point is the static constructor executed?

After the first instance is created

Before the default constructor of the first instance is called

Before the first instance is created

At the time the first instance is created

12. What happens if a class's constructors are defined with private access?

The class cannot be inherited

The class can be inherited

Instances can only be created within another class

Instances can be created anywhere in the program
