Answer:
Following are the class definition code to this question:
class UpdatedBook : BookInfo//defining a class UpdatedBook that inherits the BookInfo class
{
public:
int edition_Number;//defining an integer variable
UpdatedBook (string title,string author,int edition):BookInfo(b_title,b_author)//defining a constructor that
{
edition_Number=edition;
}
int getEdition_Number()
{
return edition_Number;
}
};
Explanation:
In this question, the "BookInfo" class is not defined, that's why we define this code as above.
In this code, a class "UpdatedBook" is defined that inherits its base class "BookInfo" inside the "UpdatedBook" class an integer variable "edition_Number" is declared, which is used to holding the integer value.
In the next step, a parameterized constructor is declared, that accepts a three-parameter and also inherits its base class parameterized constructor, and at the last, a get method is used that returns the edition number value.
