The program should allow the user to enter each student's name and his or her four test scores. It should then calculate and display each student's ayerage test score and a letter grade based on the average. Input Validation: Do not accept test scores less than 0 or greater than 100.

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.

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.Programming Project #3: 2D Array Operations Complete Programming Challenge #17 found on page 491 of the text. Include the following modifications: Input the data from a file. Provide the ability to have the user enter a file name on the command line at startup. If no command line argument is provided, then prompt the user for a filename. The first line of the file contains the number of rows in the array. Each subsequent record in the file corresponds to a row in the array. If errors occur while accessing the file or the data is invalid, display an appropriate message and exit. (In Java)
- Programming language: C/C++, Java, Python, or any other advanced programming languages Project Description: the file “IntegerArray.txt” included in this project folder contains all the 100,000 integers between 1 and 100,000 (inclusive) in some order, with no integer repeated. Your task is to compute the number of inversions in the file given, where the i-th row of the file indicates the i-th entry of an array. Because of the large size of this array, you should implement a divide-and-conquer algorithm.Array/File FunctionsWrite a function named arrayToFile. The function should accept three arguments:the name of a file, a pointer to an int array, and the size of the array. The functionshould open the specified file in binary mode, write the contents of the array to the file,and then close the file.Write another function named fileToArray. This function should accept three arguments: the name of a file, a pointer to an int array, and the size of the array. Thefunction should open the specified file in binary mode, read its contents into the array,and then close the file.Write a complete program that demonstrates these functions by using the arrayToFilefunction to write an array to a file, and then using the fileToArray function to readthe data from the same file. After the data are read from the file into the array, displaythe array’s contents on the screen.IN PYTHON - please help with lines beginning with ###TODO import csvimport random as randimport sys # define functions def load_csv_data(filename): """ load the data from csv file returns a tuple containing two lists: col_names: first row of csv file (list of strings) row_data: all other rows of csv file (list of list of strings) if error is encountered reading filename, returns -1 """ try: data = [] ### TODO - load the data from csv file ### use csv.reader to append rows of filename to data except: print("Error loading data.") return -1 # if successful, return tuple of column names and row data col_names = data[0] row_data = data[1:] return (col_names, row_data) def display_menu(): ### TODO - print the main menu print("Main Menu") print("1 - Get Clean Sample") print("2 - Calculate Total Profit in Sample") print("Q - Quit") def get_valid_menu_option(): ### TODO - get valid menu…

Your task is to readthe file, count the word frequency by ignoring the letter case, output the frequently used words (i.e.,the words occurred more than once) and the most frequently used word among all of them.Lab Scenario: Count the word in a document1. The program reads from an already provided input file: “document.txt”, which containsseveral paragraphs separated by an empty line.2. You will perform the file open operation. And then perform the read operation with your choice ofread functions and read the content of the file.3. Once you are done reading, start processing the contents of the file using a dictionary where thekey would be the word in lowercase and the corresponding values would be word frequency whichwill be the number of occurrences in the…
