Answer:

d. Inheritance.

Explanation:

The two classes are book and novel.

Since the class novel is derived from the class book, then the relationship between them (these objects) is inheritance. Inheritance is "is-a" relationship.

In this case, a novel "is a" book.

Inheritance is one of the principles of object oriented programming (OOP) in which a class, called the sub class or child class, derives, extends or inherits features of another class, called the super class or parent class or base class. In other words, in inheritance, a sub class is derived from another class in such a way that these classes have an "is-a" relationship.

In this case, the novel is the sub or child class while the book is the super, base or parent class.

Why might a variable used for output have to be of a different type then a variable used for input?

telo118 [61]

Answer:

You may use a different variable type for input in order to process the data appropriately and may use a different variable type to accommodate your program.

Explanation:

Your input may have to be different then output varying on what data you are processing.

For example, just like the last question you asked about calculating the area of the rectangle, your input MUST be converted to a different a numerical data type (i.e int or float) in order to do the math.

Based on your last question, if we didn't convert your input into a string your results wouldn't add the numbers together but only concatenate them. If I typed 3 & 5 as length & width, I would get 35 instead of 15.

Now another example is using functions (or methods whatever you want to call them), your input can be one thing and outputs another.

Let's say I want a function to tell me if I am smart. The way I want it to determine if its smart is by inputting my GPA into it, which is a numerical value. So the function would look something like this:

Code (Python)

def IsSmart(gpa):

if (gpa >= 4):

return True

else

return False

As you can see I am inputting a numerical value and it is outputting a boolean value. I can use this in a if else chain to spit out an output to the user.

What visual practice provides more information about logical relations when creating an ERD

Marina86 [1]

Answer:

Logical Data Model

Explanation:

An Entity Relationship Diagram (ERD) is a model or a diagram designed to reveal the relationship between various entities such as people, places, objects, and so on within an institution. Entity relationship diagram is also known as Entity relationship model. This model is used to design relational database by various sectors such as education, engineering, business, etc.

ERD is designed using conceptual data model, logical data model, and physical data model.

The visual practice or model that gives more insight into the logical relations among the entity is the logical data model.

The logical data model is used to illustrate more detailed operational and relational data among the entities. It is more detailed than the conceptual data.

So, the correct answer is logical data model.
