- Computer Science Create a function that can find the largest writable and non-writable file by the user in a directory without subdirectories (flat directory). This function will be part of a program named maxfile that can be invoked like this: ./maxfile <directory> You will be reading the contents of the directory passed as the only argument to your program using the function readdir(). Begin by opening the directory using opendir(), and obtain information for every file using stat(). stat() allows you to check whether a file is a regular file or a directory. (In this assignment, hard and symbolic links, special files, etc. will be ignored.) At the end, close the directory using closedir(). For Functionality 1, the input will be assumed to be a flat directory and subdirectories should not be traversed. Regular files must be separated into those for which the user has permission to write and those for which the user does not have permission to write. For each of the two types…Do not copy paste from any source else downvote Write a void function that will merge the contents of two text files containing chemical elements sorted by atomic number and will produce a sorted file of binary records. The function’s parameters will be three file pointers. Each text file line will contain an integer atomic number followed by the element name, chemical symbol, and atomic weight. Here are two sample lines: 11 Sodium Na 22.99 20 Calcium Ca 40.08 The function can assume that one file does not have two copies of the same element and that the binary output file should have this same property. Hint: When one of the input files is exhausted, do not forget to copy the remaining elements of the other input file to the result file.Write the following functions in a .py file. The functions will allow the user to add, multiply, divide, and subtract two values. These functions should be value returning functions. The py file should also include a function to calculate the area of a circle from a given radius.
- 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.C++ coding activity week 6 Additional Files: (testcode.h and runTest) These files will automatically be compiled with your code. You cannot modify them. COPIABLE CODE: #include <iostream> using namespace std; // Fill in your 6 function definitions here. Empty shells for 2 of the 6 are provided. Start by creating the other 4 empty shells to get the test code to compile. Once the file compiles, start filling in your functions. void flipMatrixVertical (int originalMatrix[][3], int flippedMatrix[][3], const int NUM_ROWS, const int NUM_COLUMNS){ // YOUR CODE HERE } void flipMatrixHorizontal (int originalMatrix[][3], int flippedMatrix[][3], const int NUM_ROWS, const int NUM_COLUMNS){ // YOUR CODE HERE } // YOUR CODE HERE (4 more functions) #include "testcode.h" // for automated grading purposes; do not remove int main() { runTest(); //Code for automatic grading. DO NOT REMOVE }You must create a function that takes a string as its sole input parameter. A string is the only return from the function. Using the input string as a basis, the function should generate a filename. This will be accomplished by capitalizing the initial letter and replacing each space in the string with an underscore, i.e. (" _ "). The function should return the newly formed filename. this code below generates filename elif command == "5": #<you will write this function here> filename = make_filename5(place) print(filename) an example would be: 'Dubai, Iraq, 2021' -------> make_filename5 ------->'Dubai,_iraq,_2021' 'spain is beautiful' ------> make_filename5 ------->'Spain_is_beautiful' 'America' ------> make_filename5 -------> 'America' elif command == "5": <you will write this function here > filename = make_filename1(place) print(filename)

Only write the function. A 50% minimum deduction will be made if main is included. No libraries or comments should be specified. (OP4) Write a function to prompt the user for the filename, open the file, and verify that it opened. If the file does not open, an error message should be printed and the user re-prompted. The function should use the string passed in for the prompt string. The function should not return until the file is open. The function prototype: void openInputFile( ifstream &, string ); ifstream& - the stream to be opened. string - the prompt to be written out to the user. Use this string when prompting the user.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. The menu in main() should look like: Encrypt a file: 1Decrypt a file: 2Exit:…
- 1. Write a program named program61.py This program will have three functions, the main() create() and retrieve(). main() will call: create() and main() then calls retrieve() create() will prompt the user to enter any number of course name | grade values. The course name ,AND calculated class GPA ( not the class grade ) are the written one value per line to a file named grades.txt ( review example of grades.txt below! ). Pressing Enter with no input value on the course name will exit the loop, close the file, print "File was created and closed" and return the bool value True to the main(). See Simple GPA Tip below. retrieve() will open and read grades.txt. The function then will print the course names and Class GPA as shown below. The average of all class GPA values should be calculated and displayed to two decimal places and then return variable used for the GPA average to the main() . See sample run below in which 2 course names were entered, but note that more or fewer…Two of the menu options (#2 and #3) are unfinished, and you need to complete the code necessary to write to and read from a binary file.
