Answer:

The answer to this question is given below in the explanation section

Explanation:

shoNum + shoNum2 = shoTotal

in this code statement, the order of operation is wrong because the calculation in programming always done at the right side of dependent variables. so the correct statement of code is

shoTotal = shoNum + shoNum2;

shoNum = 10 * 4

This statement is programmatically correct, because the ShoNum value becomes 40 after performing the multiplication operation on its assigned value (10 multiply by 4). However, it is noted that the empty space mostly ignored by the compiler. So, the correct is shoNum = 10*4;

Dim decPrice As Decimal = "$4.99"

The dollar sign is appeared in along with its value. So, if you assign value to a decimal variable, you need to assign only digit value (do not mix value with symbol or text) and also do not put quotation marks around value, if you put quotation marks around value then this value will be consider as a text value.

So, the correct statement is :

Dim decPrice As Decimal = 4.99;

shoCube= (shoSide)3

In this statement, cube is calculated of shoSide variable, mathematically it is right, but programmatically it is incorrect. Because, you missed the multiplication operation (*) between the operand shoSide and 3. it should

be as shoSide raise to power 3.

the correct statement is : shoCube = (shoSide * shoSide *shoSide);

romanna [79]

Answer:

Hi Zoom! Good question. This is particularly useful for learning sorting functions in arrays and user input handling as well. Please find the implementation below.

Explanation:

I have implemented the code in Python 2+. You can save the below code into a file called ArrayDemo.py and then run it from the command line with the command "python ArrayDemo.py". I have declared the demo_array in the code to an array of 10 unsorted integer values to test this. You can change the code if needed to have this array input by user as well and it should work fine.

Note: if you're using Python 3+ then you'll need to change the "raw_input" in the code to just "input" to make it work.

ArrayDemo.py

demo_array = [2,1,3,4,5,7,6,8,10,9]

option = 0

while (option != 4):

option = raw_input("Enter 1 to view list in ascending order, 2 to view list in descending order, 3 to choose specific poisition to view, 4 to quit the application: ")

try:

option = int(option)

if option == 1:

sort_by = 'asc'

print(sorted(demo_array, reverse=False))

elif option == 2:

sort_by = 'desc'

print(sorted(demo_array, reverse=True))

elif option == 3:

position = raw_input("Enter specific position to view (0-9): ")

try:

position = int(position)

if position < 0 or position > 9:

print("Position does not exist")

else:

print(demo_array[position])

except ValueError:

print("Position does not exist!")

elif option == 4:

break

else:

break

except ValueError:

print("Invalid input!")
