Answer:

a. myGarden.Width

Explanation:

Given: A base class named Garden contains a private field width and a property public int Width that contains get and set accessors. A child class named VegetableGarden does not contain a Width property. So the structure is as follows:

class Garden{

      private int width;

      public int Width;

}

class VegetableGarden extends Garden{

}

In the client class, we create an instance of VegetableGarden as follows:

VegetableGarden myGarden = new VegetableGarden();

From this instance the Width field can be accessed using the following mechanism:

myGarden.Width

A file extension of. Xlsm indicates what type of workbook.
Vitek1552 [10]

We have that the .xlsm <em>Format </em>is used to save Excel Macro-Enabled Workbook file

<h3>Formats</h3>

Generally file are saved in different formats for easy sorting and application on the operating system.

For instance if a music file is renamed and stored in a different format say .exe the audio file wont be recognised as an audio file and hence refuse to play.

e.g

  • .exe for a windows appication
  • ,mp3 for an audio file
  • .xlsm here is used to save Excel Macro-Enabled Workbook file

Write a program that asks the user how many numbers will be entered and then has the user enter those numbers. When this is done
KATRIN_1 [288]

Answer:

<em>The program written in Python 3 is as follows;</em>

<em>The program does not make use of comments; however, see explanation section for detailed line by line explanation of the program</em>

num = int(input("Number of Inputs: "))

mylist = []

userinput = int(input("Enter a digit: "))

i = 1

while i < num:

     mylist.append(userinput)

     userinput = int(input("Enter a digit: "))

     i += 1

   

try:

     first7 = mylist.index(7)+1

     print('The first position of 7 is ',first7)

     last7 = num - 1 - mylist[::-1].index(7)

     print('The last position of 7 is ',last7)

except:

     print('7 is not on the list')

Explanation:

This line prompts user for the number of inputs

num = int(input("Number of Inputs: "))

This line declares an empty list

mylist = []

This line inputs the first number into the empty list

userinput = int(input("Enter a digit: "))

The italicized lines represent an iteration that allows user to input the numbers into the empty list.

<em>i = 1</em>

<em>while i < num:</em>

<em>      mylist.append(userinput)</em>

<em>      userinput = int(input("Enter a digit: "))</em>

<em>      i += 1</em>

The try-except is used to check the presence of 7 in the list

try:

This checks the first occurrence of 7

     first7 = mylist.index(7)+1

This prints the first occurrence of 7

     print('The first position of 7 is ',first7)

This checks the last occurrence of 7

     last7 = num - 1 - mylist[::-1].index(7)

This prints the last occurrence of 7

     print('The last position of 7 is ',last7)

The following is executed if there's no occurrence of 7

except:

     print('7 is not on the list')
