I have been trying to work on this for a while now, and this is on excel

cluponka [151]

Answer:

=IF(INDEX(INDIRECT(C10), B10)=0,"",INDEX(INDIRECT(C10), B10))

=IF((INDEX((INDIRECT(Dept,TRUE)),Reason))="","",(INDEX((INDIRECT(Dept,TRUE)),Reason)))

Explanation:

Given

Your formula:.

=INDEX(INDIRECT("Dept"),Reason)

Dept column = C (C10)

Reason field = B (B10)

The issue with your formula is that you failed to include a statement to test the falsity of the first condition; in other words, if your if statement is not true, what else should the formula do.

The question says that

"Nest the function inside an IF function so that issues currently displaying as a 0 will display as a blank cell" this means that

if the INDEX() function returns 0, a blank should be displayed in H10 blank, instead.

So, the right formula both of these two. You can use any of them

1. =IF(INDEX(INDIRECT(C10), B10)=0,"",INDEX(INDIRECT(C10), B10))

2. =IF((INDEX((INDIRECT(Dept,TRUE)),Reason))="","",(INDEX((INDIRECT(Dept,TRUE)),Reason)))

The two does the same function; the only difference is that

(1) considers the cell itself while (2) considers the contents of the cell.

The analysis of both is that

They both use a nested indirect reference to check for the content of cells displaying 0.

The first if checks for the above mentioned; if yes, cell H10 is made to display a blank else it's original content is displayed.

Encapsulation is the process of “packaging” information prior to transmitting it from one location to another. true or false

GenaCL600 [577]

The statement that encapsulation is the process of “packaging” information prior to transmitting it from one location to another is true.

This method augments the data with successive layers of control information before transmission across a network. Each OSI (Open System Interconnection) layer is part of the encapsulation by adding a header to the data packet in the transmission network.

Modify the program you wrote for Chapter 6 Exercise 6 so it handles the following

Basile [38]

Answer:

#try except

try:

#opening the file

read_file = open('numbers.txt', 'r')

#Store the numbers in the variable file_numbers.

file_numbers = read_file.read()

#close the file

read_file.close()

#Split the number of files in list_values.

list_values = file_numbers.split()

#how many numbers are there

list_length = len(list_values)

try:

#loop it up

for i in range(list_length):

list_values[i] = float(list_values[i])

#Add up all the numbers, put into list_sum

List_sum = sum(list_values)

#heres how we average it

Average_value = (List_sum)/list_length

#print

print(Average_value)

except ValueError:

print( "File must have only numbers. Try again." )

#handles IOError exceptions

except IOError:

#Display statement

print("Trouble opening file. Try again.")

Explanation:

The python program uses the try-except exception handling method to catch errors in the code. The IOError is used for catching input and output errors in the program like file handling while the ValueError keyword in the except statement is used to catch data type errors from a return statement, calculation or user input.

Describe and compare imperative (C), functional (SML) and logic (Prolog) programming paradigms.

daser333 [38]

Answer:

Answered below

Explanation:

Imperative programming paradigm is a paradigm in which the programmer tells the machine how to change its state. It is divided into procedural programming, where programs are grouped as procedures, and object-oriented, where programs are grouped together with the properties they operate on.

Imperative paradigm is efficient, familiar and popular compared to others.

Functional programming paradigm implements all instructions as functions, in a mathematical sense. They take on an argument and return a single solution. The advantage of this, compared to other paradigms, is its abstraction and independence.

Logical programming, like functional programming, incorporates a declarative approach to problem solving. All known facts are first established before queries are made. Advantage of this paradigm is that programming steps are kept to a minimum.
