Answer:
The answer to this question is given below in the explanation section.
Explanation:
The correct answer to this question is c)field.
As we know that the feature of an entity is represented by its attribute in the database table. A database table is a set of records of different fields. Each field represents a row in a database table. Each field can contain a set of attributes related to an entity such as a paint color.
So the price of paint will be in its own field. Because there are different colors in the database table. Each color has its own record in form of a field. As you know that each field is a row in the database table. So, each row has the price of a paint color.
Other options are not correct because:
The table contains a list of fields and each field contains its own paint price. The format and file is something different and does not have any relation with the question scenario.
Answer:
Arduino
Explanation:
<em>Arduino is a free and open-source electronics platform with simple hardware and software. Arduino boards can read inputs, turn on a sensor and transform it into an output, activate a motor, and turn on an LED. Sara may direct her board by sending a series of instructions to the board's microcontroller. To accomplish so, she used the Arduino programming language and the Arduino Software (IDE), both of which are founded on Processing.</em>
To accomplish this without using a loop,
we can use math on a string.
Example:
print("apple" * 8)
Output:
appleappleappleappleappleappleappleapple
In this example,
the multiplication by 8 actually creates 8 copies of the string.
So that's the type of logic we want to apply to our problem.
<span>def powersOfTwo(number):
if number >= 0:
return print("*" * 2**number)
else:
<span>return
Hmm I can't make indentations in this box,
so it's doesn't format correctly.
Hopefully you get the idea though.
We're taking the string containing an asterisk and copying it 2^(number) times.
Beyond that you will need to call the function below.
Test it with some different values.
powersOfTwo(4) should print 2^4 asterisks: ****************</span></span>
