Experiment 17 Directories I. Objective After performing this activity, you should be able to 1. Perform operations on directories in assembly language. II. Introduction This experiment covers a number of extended DOS services for disk operations introduced by DOS 2.0 and 3.0. Many of these services are much simpler than the original DOS services are generally recommended. These operations involve the use of an ASCIIZ string to initially identify a drive, path and filename; a file handle; and special error return codes. Int21H Service 39H: Creating a directory Function 39H creates a subdirectory, just like the DOS command MD For example, diname, dh 'C:\TASM',0 mov ah, 39h lea dx dirname int 21h A successful operation creates the subdirectory TASM in drive C. An error sets the carry flag and returns code 03 (path not found or invalid path) or 05 (access denied or directory already exists) in register AX. INTIH Service 3AH: Removing a directory Function 3AH deletes a subdirectory. just…

(python) Write a function startWith(File, Let) that takes a file name and a letter. Each line in the file contains 1 word. The function should store a new file with all the words that start with letter Let. Example: startWith (‘Test1-3.txt’, ‘A’)   Source File: (Test1-3.txt) Output File: (Test1-3New.txt) Hi Airport Airport Apple Hello   Apple   Mango

(Class Average: Reading Student Records from a CSV File) Use Python Use the csv module to read the grades.csv file from the previous exercise (exercise 9.3). Display the data in tabular format, including an additional column showing each student’s average to the right of that student’s three exam grades and an additional row showing the class average on each exam below that exam’s column. This is exercise 9.3 # Importing csv moduleimport csv# empty list to store datadata = []columns = ["firstname", "lastname", "grade1", "grade2", "grade3"]filename = "grades.csv"for i in range(3):firstname = input("Enter First Name : ")lastname = input("Enter Last Name : ")grade1 = float(input("Enter Grade 1 : "))grade2 = float(input("Enter Grade 2 : "))grade3 = float(input("Enter Grade 3 : "))data.append([firstname, lastname, grade1, grade2, grade3])print()# write data and columns as csv filewith open(filename, 'w') as csvfile:# creating a csv writer objectcsvwriter = csv.writer(csvfile)# writing the…

(java programming language) Write a program to read and store four student’s name and their CGPA, sort them into an order name, based on CGPA from the smallest to the largest, then print them out. The student’s name and their CGPA values should be typed in by the user in response to a prompt message. Save the file as SortName_yourID.java

4. Write a C++ code that: 1. Read the sequences in the provided fasta file (unzip the attached file) 2. Build a Kmer count table (use array) where k = 10%; 3. Build a histogram table of size 200 in which we store the frequency of counts collected in step 2. if frequency is 200 or more, increment the last element in the histogram array. 4. Report the results of histogram table to screen as the following: Kmer-Count Frequency 1 100 80 3 40 20 .... 200 300

My money is getting out of hand and I don't know how much is the total now. Can you please help me add them all up? Instructions: In the code editor, you are provided with a main() function that asks the user for 3 integers.Your task is to create 3 pointers and name them: a_ptr, b_ptr, and c_ptr. Then, assign the address of a to a_ptr, b to b_ptr, c to c_ptr. Make sure to do this before the printf statement found at line 16.Input 1. First integer 2. Second integer 3.

HCI is (Human Computer Interaction) Answer the following five statements by first stating whether it is true or false and then given one sentence for justifying your answer a) You drag a folder to make a copy of its contents. An animation appears on the screen, showing files moving from one folder to another. This is an example of feedback. b) In augmented reality a screen is composed of a computer animation of the reality. c) The Model Human Processor is used in HCI to model complex cognitive processes d) Petri Nets can be helpful in modeling concurrent activities in a user interface. e) Gestalt is important to HCI as it offers tools to understand scenes.

(pickle Object Serialization and Deserialization) We mentioned that we prefer to use JSON for object serialization due to the Python documentation’s stern security warnings about pickle. However, pickle has been used to serialize objects for many years, so you’re likely to encounter it in Python legacy code. using the pickle module’s dump function to serialize the dictionary into a file and its load function to deserialize the object. Pickle is a binary format, so this exercise requires binary files. ”Reimplement your solutions to Exercises 9.6. Use the file-open mode 'wb' to open the binary file for writing and 'rb' to open the binary file for reading. Function dump receives as arguments an object to serialize and a file object in which to write the serialized object. Function load receives the file object containing the serialized data and returns the original object. The Python documentation suggests the pickle file extension .p.  Excercise 9.6 code import jsondef main():n =…
