Write a program to copy an existing text file from your hard disk to another file that you will call: Your Last Name.txt, e.g. if your last name was Smith, the output file name would be Smith.txt. You can create a text file and add two or three lines of text to it. You may use the attached program as your program or write your own. Please note the inclusion of at the top of the program. Also pay attention to the open and close statements in the program.
// File: CopyFile.cpp
// Copies file InData.txt to file OutData.txt
#include // for the definition of EXIT_FAILURE
#include // required for external file streams
#include
using namespace std;
// Associate stream objects with external file names
#define inFile "InData.txt"
#define outFile "OutData.txt"
// Functions used ...
// Copies one line of text
int copyLine(ifstream&, ofstream&);
int main()
{
// Local data ...

Read a source file name (text file) from the user (e.g, myprog.cpp) and produce a copy ofthe same. Also display the following statistics:1. Number of lines of the code?2. Total characters?
Question:
Display all the names of a given length from names.dat. This file is in binary. Each entry is in the format: name length (integer) and name (string).
There are no String reading methods for binary files. You'll have to figure out how to use the length value and readChar method to read all the names.

- Suppose that you have two text files that contain sequences of integers separated by white space (blank space, tabs, and line breaks). The integers in both files appear in sorted order, with smaller values near the beginning of the file and large values closer to the end. Write a pseudocode algorithm that merges the two sequences into a single sorted sequence that is written to a third file.arrow_forwardWrite a program to read the file numbers.txt created in part 1 that was saved to your home directory. As you read each number, keep track of how many times each of the numbers appear in the file (use a dictionary with the number as the key and count as the value). Print the count of each number and the sum of all the numbers in the file.arrow_forwardUse Python write a program that reads a file and writes out a new file with the lines in reversed order (i.e. the first line in the old file becomes the last one in the new file.)arrow_forward
- Count how often each bit is set in all the bytes of the given binary file. Open the file with the given name as a binary file. Count how often each bit is set in all the bytes of the file. A byte value returned by infile.get outside the range from 0 to 255 indicates the end of the file. Once you have a byte, you can get the bits like this: for (int i = 0; i < 8; i++) { if (byte % 2 == 1) { // The i-th bit is set } byte = byte / 2; } CODE SHOWN BELOW: #include <iostream>#include <fstream>#include <string> using namespace std; int main(){int bit_counts[8];for (int i = 0; i < 8; i++) { bit_counts[i] = 0; }fstream infile;string filename;cin >> filename; /* Your code goes here */ int largest = 0;for (int i = 0; i < 8; i++){cout << i << ": " << bit_counts[i] << endl;}return 0;}arrow_forwardWrite a program to change the alphabets in a file in following manner.

The expansion involves writing all records to a file (use fprintf, call the name of the file csv). The displayed data must be accessed (and thus written) from data structure (i.e. array of structs). The format written to the file should be one line per record, with each field separated by a comma (‘,’) program should then output the number of lines in the file.test the program by creating a text file with at least 10 lines of text (of any composition). Use notepad++ to create the data file. #include<stdio.h>#include<stdlib.h> //Structurestruct Person{ char name[10];int age;float wage; }; //Main int main (int argc, char **argv) { FILE* f; if (argc != 2) { printf("No filename in the argument"); return 1; } f = fopen(argv[1], "r"); if (f == NULL) { printf("The file cannot be opened successfully:…arrow_forwardWrite a program that reads the strings from file SortedStrings. txt and report whether the strings in the files are stored in ascending order.
