Question Discussion & Solution

Concept:

In general, each object contains three object associated attributes:

• Object prototype: It is kind of reference/indication to another object from which properties are inherited.
• Object class: It is a kind of string which classifies the type an object.
• Object's extensible flag: It simply specifies that whether some new properties are added to the object

Logic:

Train, Bus, and Boat are all vehicles,

Whereas a wheel is not a vehicle but a part of it.

Hence, "Wheel" is the odd word.

1024 bytes = 1 kilobyte.

1024 kilobytes = 1 Megabyte.

1024 megabytes = 1 Gigabyte.

1024 gigabytes = 1 Terabyte.

A constructor is a member function of a class that initializes objects of a class. In C++, Constructor is automatically called when an object (instance of a class) creates. It is a special member function of the class.

Syntax

class_name(parameter1, parameter2, ...)

{

    // constructor Definition

}

Default Constructor

It is the constructor that doesn’t take any argument. It has no parameters.

Parameterized Constructors

It is possible to pass arguments to constructors. Typically, these arguments help initialize an object when it is created. 

Copy Constructor

A copy constructor is a member function that initializes an object using another object of the same class.

Explanation:

• The metallic property of the elements of the periodic table decreases when we move across the group whereas it increases when we go down the group, as we go down the number of electrons increases and thereby their distance from the nucleus increases. 
• This increase causes them to shed more electrons and thereby have a greater electropositive or metallic character. 

Among the given compounds Na shows maximum Metallic character.
