Using C program, thanks appreciate your help! Program Requirements: There should be 2 separate programs for write and Read. mknod() Creates the named pipes Define the length of your message on a buffer Define your descriptor use the open() O_WRONLY O_RDWR In your program, consider the following: Use the read() function to read nbytes from the file associated with the andle, and places the characters read into the buffer. Make sure you indicate the number of characters on the reader output. use gets() to read the characters from stdin() that are stored in your buffer. show the parent and chile terminal screenshots (During the code simulation).

- WriteaC++programthatpromptstheusertoenterafilenamethatcontains the total mark of students. Each line in the input file contains a student name followed by the student’s total mark. The program should ask the user for the passing threshold (i.e. student whose total mark is greater than or equal the threshold will pass the course) and copy the students who pass the course to a new file (the name of the output file is specified by the user). Moreover, the output file should be format so that all the marks are displayed with two digits after the decimal point. The width for the names and marks fields should be eight and seven, respectively. A sample input and output files are shown below (the passing mark in this sample is assumed to be 60). Total.txt Ahlam 80.123 Bader 83.1 Nabil 91.25 Khoula 70 Saif 55.333 Salem 50 Sultan 92.5 Qais 77.2#Problem #1 Searching for a Item in a File Write a program named SearchFile.py that reads in a list of items from a text file and looks for the presence of one that the user enters from the keyboard. During the search, have a loop that ends when they type in DONE for the word. For ours, we will search for a bird name but the idea would be applicable for any searching in a file.INSTRUCTION: C++ Language Create a function that writes to a file named Inventy.txt the information of 8 items. Ask the user for the item's name, the item's quantity in storage, and the item's price and write it to the file. Create a function that reads the file and items' quantity and price to two different arrays. Create a function that computes the subtotal of each item. Implement all functions inside the main program and the computed value should be displayed with the item's name.
- This Python Lab 9 Lab: Write a file copying program. The program asks for the name of the file to copy from (source file) and the name of the file to copy to (destination file). The program opens the source file for reading and the destination file for writing. As the program reads each line from the source file and it writes the line to the destination file. When every line from the source file has been written to the destination file, it close both files and print “Copy is successful.” In the sample run, “add.py” is the source file and “add-copy.py” is the destination file. Note that both “add-copy.py” is identical to “add.py” because “add-copy.py” is a copy of “add.py”. Sample run: Enter file to copy from: add.py Enter file to copy to : add-copy.py Copy is successful. Source file: add.py print("This program adds two numbers") a = int(input("Enter first number: ")) b = int(input("Enter second number: ")) print(f"{a} + {b} = {a+b}") Destination file:…Using C++Put your entire completed visual studio solution in a zip archive and upload it as: assignment01YourName.zip. Write the program that allows the user to sort using the Bubble Sort, Selection Sort, Insertion Sort and Shell Short The program should be able to read in data from a binary file. The first element of the binary file will be used to tell how many elements to read in. Once all the data has been read in, the program should sort the data. The user should be able to choose which algorithm to use to sort the data. The program should print the time before and after the sort. The last part of the program should prompt the user for a lower and upper bound. These two value should then be used to decide how much and which part of the array will be display. You should test all of the sorts on each of the data files. In a separate word document include a short writeup for each sort that looks something like this: Insertion Sort: 1,000,000 Random: 5 minutes 1,000,000…The function print_last_line in python takes one parameter, fname, the name of a text file. The function should open the file for reading, read the lines of the file until it reaches the end, print out the last line in the file, report the number of lines contained in the file, and close the file. Hint: Use a for loop to iterate over the lines and accumulate the count. For example: Test Result print_last_line("wordlist1.txt") maudlin The file has 5 lines.
- To do term Program 5: Improve the file copy program from Lab 9 so that it will make sure the user enters a file that exists. If a file doesn’t exist, the open function will raise the FileNotFoundError. You do not need to check if the destination exists since a file doesn’t need to exist to write it. Instead of copying the content of the source as exact, it only copies non-empty lines and it also prepend each line with a line number. A line is empty if the length of the line stripped of white space from both end is 0. The code segment below shows how to strip white space and getting the length of the string. If the length of the line is zero, the line is a blank line. line1 = " " line2 = " aa " print(len(line1.strip())) # 0 print(len(line2.strip())) # 2 In the sample run, “add.py” is the source file and “add-copy.py” is the destination file. Note that “add-copy.py” contains only non-blank lines from “add.py” and each line in “add-copy.py” is labelled with a line number. Sample run:…Write a write_scores function that opens the file, and writes scores and names from lst_scores and lst_names into the file. An example function call is below. Make sure to handle a file error. Assume good input in both lists. Function name: write_scoresParameters: lst_scores, a list of ints; lst_names, a list of strings; file_name, a string Purpose: Writes the names and scores to the file name, with one name and one corresponding score per line.Example function call: (attached) After this code runs, the file final_grades.txt should read: Ayesha 96 Paolo 99 Ahmed 93 Anna 94All I need is the main.cpp file Programming Specifications: Task: Two files have been provided (wordcounter.h and wordcount.cpp). You must open a text file, read in each word until end of file, add each word to the WordCount library and print the report. Your program must request a filename of a text file that contains words to count. You must check to see if it is a valid file and issue an error message if not and request a new file name until a valid one is entered. You must have at least one function that either passes in a parameter and at least one function that returns a value. You can have a single routine that does both. You must declare the class object properly, use AddWord() to add the word to the catalog and use PrintSummary() to produce the output. Design Considerations: The file will contain only words (no punctuation or special characters) less than or equal to 13 letters. There will be no limit to the number of words. You must open the file and read each…
- In Python, Create a program that will write 100 integers created randomly in a file. The integers will be separated by a space in the file. Read the data back from the file, and display the sorted data. The program should prompt the user to enter a file name. Utilize the following function headers for this problem: Main() WriteNumbers(filename) ReadNumbers(filename) The main function will first prompt the user to enter the filename. Then the main function calls WriteNumbers-then ReadNumbers. The WriteNumbers function opens an output file and writes 100 random numbers as long a large string text. Do not use lists for this problem- please just write a random number followed by a space 100 times. The ReadNumbers function will then read the text file and display the numbers sorted. In order to sort the numbers, read the big string and then split it into a list. Now convert them into integers by using list comprehension and then sort the list. Loop through the list and print each…This is Python Program 5: Improve the file copy program from Lab 9 so that it will make sure the user enters a file that exists.

Java eclipse Your Task: Write a program that creates a file - Your program should request the user to enter strings until they type the word "STOP". You should then sort these strings in alphabetical order (A-Z) and save them to a file. This file should be named Problem21.txt Note: Your program should handle all types of inputs without crashing.
