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

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.
You have a huge text file with words in it. Find the smallest distance (in terms of number of words) between any two words in the file. Can you optimise your solution if the procedure will be performed several times for the same file (but different pairs of words)?

How many passes will it take to sort the file completely?arrow_forwardWrite a program that expands on the program below (i.e. reading data of each record in the file and storing it into data structure). 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).

- Write a program that reads two input files whose lines are ordered by a key data field. Your program should merge these two files, writing an output file that contains all lines from both files ordered by the same key field. As an example, if two input files contain student names and grades for a particular class ordered by name (the key field), merge the information as shown below. File 1 and file 2 are supplied. Here is an algorithm to merge the data from two files: Read a line from each data file While the end of both files has not been reached While the end of both files has not been reached Write the line from file 1 to the output file and read a new line from file 1. Else Write the line from file 2 to the output file and read a new line from file 2. Write the remaining lines (if any) from file 1 to the output file. Write the remaining lines (if any) from file 2 to the output file. See the Merging Filesslides attachedto the project in Canvasfor a visual look at this algorithm.arrow_forward1.Write a program that reads words from a text file (.txt format) and displays all the nonduplicate words in ascending order.

- First, take your program and add one more feature: at the end, just before you close the file, write the word “END” all by itself on a line. Run that program once to create a file of items with “END”. Instead of reading from cin and writing to a file, you read from your file and write to cout. The only tricky part is deciding when to stop reading. In your previous code, you stopped reading when the user said they didn’t want to continue. For the new code, keep reading until you read “END” for the name of the produce. You can use “==” on strings, so if (product name == ”END”) will tell you that you can stop reading. My code: #include<iostream>#include<string.h>#include<fstream>using namespace std; int main(){ string filename; cout<<"Enter the name of the file to store the information"<<endl; getline(cin,filename); ofstream fileptr(filename.c_str()); if(!fileptr.is_open()) { cout<<"Couldn't open a file"<<endl; }…arrow_forwardWrite a program that reads the contents of a text file and prints the letter that starts the mostunique words in that file.arrow_forwardanswer this question in Python (using numpy )arrow_forward
