a) Open a text file "input.txt" and read all characters into an array in memory. Limit the length of the array to 1000 bytes. The maximum number of characters to be read should be 1000 characters. The actual number of characters depends on the file length. MARS provides the system calls for opening and reading a text file. If the "input.txt" file does not exist in the same folder then the program should display an error message and terminates. Error: input.txt does NOT exist. b) If the "input.txt" file exists, then print the content of the array as one long string. For example, This is a test file for testing MIPS assignment 2. It contains letters and digits, such as 12345. c) Traverse the array character by character. Count all letters, digits, and words. A word begins with a letter and ends with a letter A-Z or a-z. You can detect the end of a word by checking that the next character is not a letter. A single letter is counted as a word. Do not distinguish between capital and lowercase letter. Then, display the total count of letters, digits, and words. For example, Letters = 71 Digits = 6 Words = 16

Given a text file containing the availability of food items, write a program that reads the information from the text file and outputs the available food items. The program first reads the name of the text file from the user. The program then reads the text file, stores the information into four separate arrays, and outputs the available food items in the following format: name (category) -- description Assume the text file contains the category, name, description, and availability of at least one food item, separated by a tab character. Ex: If the input of the program is: food.txt and the contents of food.txt are: Sandwiches Ham sandwich Classic ham sandwich Available Sandwiches Chicken salad sandwich Chicken salad sandwich Not available Sandwiches Cheeseburger Classic cheeseburger Not available Salads Caesar salad Chunks of romaine heart lettuce dressed with lemon juice Available Salads Asian salad Mixed greens with ginger dressing, sprinkled with sesame Not available Drinks Water…

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.
The 2 pictures are the beginning of the lab. The below is for part 2. read_file(0, clear_file); // Read in a file with of unknown length, getting the length from the file read. clear_file is a string containing the path to the clear text file. This function returns a char array created with memory allocation. read_file(len, clear_file); // Where len > zero, reads len chars from a file. clear_file is a string containing the path to the clear text file. This function returns a char array created with memory allocation. write_file(0, key, key_file); // Writes a string to file until the \0 char is reached. key is the string of random chars and key_file is a string containing the path of the text file. write_file(len, cipher, cipher_file); // Where len > zero, writes len chars to a file. cipher is the cipher string of chars and cipher_file is a string containing the path of the text file.

Computer Science Write a program that uses 3 command line arguments to search a list of float numbers in a file and prints out the result of whether the number was found or not on the console. Also, it prints the array in the reverse order (not sorted but reverse order of how the numbers were read in). The first argument is the name of the input file which has the numbers to be searched, the second is an integer specifying how many numbers are in the input file and the third argument is the float number being searched for. Use dynamic memory allocation for the array and use a function (that returns a boolean value) to do the searching. Also make sure in the beginning of your program, that the program will execute only if exactly three arguments (other than executable name itself) are specified. at the command line.
Python - Next Birthdate In this task, we will write a program that reads birthdate data from a given CSV file, and given the current date, determines which person's birthday will be celebrated next. Create a function with the following signature: nextBirthdate(filename, date) filename: parameter, which represents the CSV filename. date: parameter, which represents the current date. The function should open the CSV file, read the birthdate data, and determine which person's birthday will be celebrated next, given the current date. The name of the person should be returned. In other words, given a date, find the person whose birthday is next. Sample Run birthdates.csv Draven Brock, 01/21/1952 Easton Mclean, 09/02/1954 Destiny Pacheco, 10/10/1958 Ariella Wood, 12/20/1961 Keely Sanders, 08/03/1985 Bryan Sloan,04/06/1986 Shannon Brewer, 05/11/1986 Julianne Farrell,01/29/2000 Makhi Weeks, 03/20/2000 Lucian Fields, 08/02/2018 Function Call nextBirthdate("birthdates.csv", "01/01/2022") Output…
Q4. Write an algorithm of a program to read from a file. The user should be able to get the option to input the file name. He is supposed to read first 100 bytes from the file. After the reading is done, the file should be closed. If the file is not available, the program should be closed immediately. You should mention "System call" beside each instruction which are supposed to use a system call function. *
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.

If the user selects the first option, they should be repeatedlyprompted for the names and module results (4CS001, 4CS015 and 4CI018) ofstudents until the users enters a blank string, storing the information in adictionary, before writing the data to a text file in JSON or CSV format.If the user selects to view student grades, any data stored in the results fileshould be read, loaded into a dictionary and presented to the user.Make sure to validate all inputs and utilise exception handling to avoid crashes.
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:…

Write code to check the file state. If the file fails to open, display a message and exit the program. 5. Declare an array that holds 20 integers. Read the 20 integers from the file into the array. 6. Write a function that accepts the filled array as a parameter and determines the MAXIMUM value in the array. Return the maximum value from the function (the function will be of type int). 7. Print ALL the array values AND print the maximum value in the array using a range-based for loop. Use informational messages. Ensure the output is readable.
