- Create File comparators that arrange files in ascending/descending order of file size, ascending/descending order of file name, and ascending/descending order of last modification date. Employ these comparators in LS, a programme that accepts a command-line input and lists the files in the current directory in a certain order, such as "-t" to sort by timestamp.To break ties, support several flags. Be certain you use a reliable sort.(This is for DevC++. I use version 5.11) Edit the following code to read the input for 10 students from a file testData1.txt and output the average of scores for 10 students using a loop. #include <fstream>using namespace std;#include <iomanip>int main(){string name1,name2,name3;double score1,score2,score3;char c1,c2,c3;double avg;ifstream inputFile;ofstream outputFile;inputFile.open("testData1.txt");outputFile.open("Results.txt");inputFile.clear();inputFile>>name1>>score1>>c1;inputFile.clear();inputFile.ignore(200,'\n');inputFile>>name2>>score2>>c2;inputFile.clear();inputFile.ignore(200,'\n');inputFile>>name3>>score3>>c3;avg =(score1 + score2 +score3)/3.0;outputFile << endl<<setw(20)<<left<<"Name" <<setw(20)<<"Score"<<setw(20)<<left<<"School Year";outputFile << endl<<setw(20)<<left<<"----"…// switch_stdout.c: demonstrates use of dup2() and dup() to redirect // standard output to a new location temporarily and then restore it. #include <stdio.h> #include <stdlib.h> #include <unistd.h> #include <fcntl.h> int main(){ int stdout_bak = dup(STDOUT_FILENO); // make a backup of stdout system("rm -f mystery.txt"); // remove file using a shell command int out_fd = open("mystery.txt", // open file mystery.txt O_WRONLY|O_CREAT, // for writing, create if needed S_IRUSR|S_IWUSR); // give user read/write permission if(out_fd == -1){ // check for errors opening file perror("Couldn't open file 'mystery.txt'"); exit(1); // bail out if open fails } printf("1.

- Create comparators for the type File that arrange files according to file size, file name, and last modification date, in that order, in addition to ascending and descending. Use these comparators in the LS programme, which accepts a command-line input and lists the files in the current directory in the desired order, for example, "-t" to sort by timestamp.To break ties, back many flags. Use a stable sort, please.The following code is for the code file namedpipe_p1.c. // This process writes first, then reads #include <stdio.h> #include <string.h> #include <fcntl.h> #include <sys/stat.h> #include <sys/types.h> #include <unistd.h> int main() { int fd; // FIFO file path char * myfifo = "/tmp/myfifo"; // Creating the named file(FIFO) // mkfifo(<pathname>, <permission>) mkfifo(myfifo, 0666); char arr1[80], arr2[80]; // Open FIFO for write only fd = open(myfifo, O_WRONLY); // Take an input arr2ing from user. // 80 is maximum length printf("your message: "); fgets(arr2, 80, stdin); // Write the input arr2ing on FIFO // and close it write(fd, arr2, strlen(arr2)+1); close(fd); // Open FIFO for Read only fd = open(myfifo, O_RDONLY); // Read from FIFO read(fd, arr1, sizeof(arr1)); // Print the read message printf("Received: %s\n", arr1); close(fd);…Modify the program 11-10 from pages 753-755 as follows: 1. To Length class files (Length.h and Length.cpp) add the operator overload for stream insertion (<<) and stream extraction (>>) from page 759. You should not use the modified version of class Length from page 759 because it contains more operator overloads. Instead of typing you can use copy/paste from Length1.h and Length1.cpp respectively. 2. In main() replace the lines 11-16 with appropriate usage of stream extraction overload (>>) to change "first" and "second" objects with values inputted by the end user. 3. In main(), replace the output on lines 21,22 and 25,26 with appropriate usage of stream insertion (<<) operator. The resulting output should be identical with the unmodified version of the program. 11-10: // This program demonstrates the Length class's overloaded // +, -, ==, and < operators. #include <iostream> #include "Length.h" using namespace std; int main() { Length first(0),…

The program should concatenate the content of thenfiles separated by’\n’and write the result on the standard output and also intooutput.txt.Read the input files and write the output file using the binary mode. Use a char buffer of size64bytes and chunks of size1byte when reading and the same buffer with chunks of size64bytes(or less if the last write and file size is not a multiply of64) when writing. input: 3 , file1.txt , file2.txt , file3.txt output: Concating the content of 3 files ... The result is: The first file’scontent. The second file’s content. The third files’s content. The result was written into output.txtProfessor Potter, a punning pedantic, practices puzzling her students. She has left a secret message, of unknown length, encoded in a file for you to unravel. The setup is simple: each line of the file contains one char and one non-negative integer. The key to reading the message is organizing the characters in the proper order. The integer indicates the position of the character within the message. For example: e 2 b 1 a 3 h 5 c 4 spells 'beach' when unraveled. Write a program that will: Ask the user for the name of a file Check to see that the file exists and contains some data. Open and read this file exactly once Using your MessageDecoder class, unravel and display the message Offer to do it again on another file Required classes: You will create and submit 2 classes: MessageDecoder class: Responsible for converting a scrambled message file into plain text. Contains a public method getPlainTextMessage() that returns the String object. The scrambled file must be scanned only once…
