- Our requirement is to keep information of students who are taking “Introduction to Python” in Fall-2021 in a text file named ‘Students.txt’. The first line of text in this file will be header line as follows Creates a file named ‘Students.txt’ if it does not exist (use os module), writes/adds the header as shown in picture above and writes/adds records of at least 15 students. ( Do not solve this one, i used this one for reference) Creates another file named ‘UpdatedStudents.txt’ where the information is same as Students.txt, except the one thing, adds ‘GPA’ in header and GPA value based on reading Total-Marks.COMPLETE TO DO's (do not copy other responses to this question if you do ill downvote) recv.cpp #include <stdio.h>#include <stdlib.h>#include <string.h>#include <fcntl.h>#include <mqueue.h>#include <sys/stat.h>#include <sys/types.h>#include <sys/mman.h>#include <unistd.h>#include <signal.h> // The name of the shared memory segment#define MSQ_NAME "/cpsc351queue" // The name of the file where to save the received file#define RECV_FILE_NAME "file__recv" #define MQ_MSGSIZE 4096 /*** Receive the file from the message queue*/void recvFile(){ // TODO: Define a data structure // of type mq_attr to specify a // queue that can hold up to 10 // messages with the maximum message // size being 4096 bytes // The buffer used to store the message copied // copied from the shared memory char buff[MQ_MSGSIZE]; // The total number of bytes written int totalBytesWritten = 0; // The number of bytes written int…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.
- 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.

Perform basic file I/O. Use structs, pointers, and strings. Use dynamic memory. This assignment asks you to sort the letters in an input file and print the sorted letters to an output file (or standard output) which will be the solution. Your program, called codesolve, will take the following command line arguments: % codesolve [-o output_file_name] input_file_name Read the letters in from the input file and convert them to upper case if they are not already in uppercase. If the output_file_name is given with the -o option, the program will output the sorted letters to the given output file; otherwise, the output shall be to standard output. In addition to parsing and processing the command line arguments, your program needs to do the following: You need to construct a doubly linked list as you read from input. Each node in the list will link to the one in…

- program two applications that will work together to perform reduction on multiple files. Reduction operation is summing the contents of the file. You may assume files contain a number on each line and there are no more than 100000 numbers in the file. The first program should get a directory name as argument. Then it should obtain the list of files in the directory either by using ls program and pipes or by using readdir system call. This program then should fork and execute the second program, passing the folder name and the filename. The second program should get the name of directory and the filename. Then it should read the file into an array. The reduction operation should be done using multiple threads. To get full points, you must write your program in a way that will actually perform operation in parallel. If necessary use mutexes, but it is possible to the task without them. Print out the summation. Finally, write a document that will explain your code. It should also have a…In this assignment you will be writing several functions that process files and dictionaries to encryptand decrypt messages. A dictionary will be used to create a random substitution cypher. Each letterof the alphabet will be mapped to another random letter in the alphabet. No letter will map or bemapped to any duplicate letter. For example given the partial dictionary below you can encrypt amessage.Be sure to use the starter file provided so you can see the appropriate outputs.
