A file concordance tracks the unique words in a file and their frequencies. Write a program that displays a concordance for a fi

victus00 [196]

Answer:

I am writing a Python program.

def concordance(filename): # function that takes a file name as parameter and returns the concordance for that file

file = open(filename,"r") #opens file in read mode

unique={} #creates and empty list

for word in file.read().split(): #loops through every word in the file

if word in unique: # if words is already present in the list

unique[word] += 1 #add 1 to the count of the existing word

else: #if word is not present in the list

unique[word] = 1 #add the word to the list and add 1 to the count of word

file.close(); # close the file

for x in sorted(unique): #sort the list and displays words with frequencies

print(x, unique[x]); #prints the unique words and their frequencies in alphabetical order

#prompts user to enter the name of the file

file_name=input('Enter the input file name: ')

concordance(file_name) #calls concordance method by passing file name to it

Explanation:

The program has a function concordance that takes a text file name as parameter and returns a list of unique words and their frequencies.

The program first uses open() method to open the file in read mode. Here "r" represents the mode. Then creates an empty list named unique. Then the for loop iterates through each word in the file. Here the method read() is used to read the contents of file and split() is used to return these contents as a list of strings. The if condition inside the loop body checks each word if it is already present in the list unique. If the word is present then it adds 1 to the count of that word and if the word is not already present then it adds that unique word to the list and assign 1 as a count to that word. close() method then closes the file. The second for loop for x in sorted(unique): is used to display the list of unique words with their frequencies. sorted() method is used to sort the list and then the loop iterates through each word in the list, through x, which acts like an index variable, and the loop displays each word along with its frequency.

Write the 8-bit signed-magnitude, two's complement, and ones' complement representations for each decimal number: +25, + 120, +

pshichka [43]

Answer:

Let's convert the decimals into signed 8-bit binary numbers.

As we need to find the 8-bit magnitude, so write the powers at each bit.

Sign -bit 64 32 16 8 4 2 1

+25 - 0 0 0 1 1 0 0 1

+120- 0 1 1 1 1 0 0 0

+82 - 0 1 0 1 0 0 1 0

-42 - 1 0 1 0 1 0 1 0

-111 - 1 1 1 0 1 1 1 1

One’s Complements:

+25 (00011001) – 11100110

+120(01111000) - 10000111

+82(01010010) - 10101101

-42(10101010) - 01010101

-111(11101111)- 00010000

Two’s Complements:

+25 (00011001) – 11100110+1 = 11100111

+120(01111000) – 10000111+1 = 10001000

+82(01010010) – 10101101+1= 10101110

-42(10101010) – 01010101+1= 01010110

-111(11101111)- 00010000+1= 00010001

Explanation:

To find the 8-bit signed magnitude follow this process:

For +120

put 0 at Sign-bit as there is plus sign before 120.

Put 1 at the largest power of 2 near to 120 and less than 120, so put 1 at 64.

Subtract 64 from 120, i.e. 120-64 = 56.

Then put 1 at 32, as it is the nearest power of 2 of 56. Then 56-32=24.

Then put 1 at 16 and 24-16 = 8.

Now put 1 at 8. 8-8 = 0, so put 0 at all rest places.

To find one’s complement of a number 00011001, find 11111111 – 00011001 or put 0 in place each 1 and 1 in place of each 0., i.e., 11100110.

Now to find Two’s complement of a number, just do binary addition of the number with 1.

During which stage does the central processing unit analyze the instruction and encode it in the form of a number, and then gene

guapka [62]

Answer:

a. fetch

Explanation:

The device collects a program command from its memory during the run cycle of the fetch.

It then defines and performs the activities needed for that command. The CPU continuously repeats the cycle of fetching, decoding, and executing a command while the computer is switched on.
