- Consider that we need to copy first 100 bytes from a binary file and paste that to another existing binary file. If the source file does not exist, then close the program. If the destination file does not exist, then create a new file otherwise overwrite it. After successful completion of data transfer, both files should be closed and the program should terminate. Write down the algorithm and point out the steps where system calls are used. [you can just write "system call' beside the line where you think a system call should be called]Write a C program, called reverse, using standard I/O functions, to take a file as inputthen copies it to another file in reverse order. That is, the last byte becomes the first,the byte just before the last one becomes the second, etc.The program call should look like:reverse fileIn fileOutSubmit your source code and script filesWrite a C program, called reverse, using standard I/O functions, to take a file as inputthen copies it to another file in reverse order. That is, the last byte becomes the first,the byte just before the last one becomes the second, etc.The program call should look like:reverse fileIn fileOut
- 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;}Explain in your own words: a.) What is a file’s read position? Where is the read position when a file is first opened for reading? b.) Why should a program close a file when it’s finished using it?Write a C++ program that accepts lines of text from the keyboardand writes each line to a file named text.dat until an empty line is entered. An empty lineis a line with no text that’s created by pressing the Enter (or Return) key.b. Modify Program 9.6 to read and display the data stored in the text.dat file created inExercise 3a.
- Only answer without explanation Q2. To redirect “nothing” to an existing file is equal to emptying the file. This is called as__________.Suppose a file named "numbers.txt" is on the disk and that it contains this data: 374013 What can you say about the file? Answers: A. It contains the characters '3', '7', '4', '0', '1', and '3' B. It contains the characters '3', '7', ' ', '4', '0', ' ', '1', and '3' C. It contains the characters '3', '7', '\n', '4', '0', '\n', '1', and '3' D. It contains the number 37, the character '\n', the number 40, the character '\n', and the number 13 E. It contains the numbers 37, 40, and 13Correct answer will be upvoted else downvoted. Computer science. Homer has two companions Alice and Bob. The two of them are string fans. At some point, Alice and Bob choose to play a game on a string s=s1s2… sn of length n comprising of lowercase English letters. They move in turns on the other hand and Alice takes the primary action. In a move, a player should pick a file I (1≤i≤n) that has not been picked previously, and change si to some other lowercase English letter c that c≠si. At the point when all files have been picked, the game closures. The objective of Alice is to make the last string lexicographically as little as could really be expected, while the objective of Bob is to make the last string lexicographically as extensive as could be expected. The two of them are down specialists, so they generally mess around ideally. Homer is certainly not a game master, so he thinks about what the last string will be. A string an is lexicographically more modest than…
- 2. For reading and for processing data of employee records stored in a file named employee.txt,the contents of it need to be reversed from end to beginning. Write a C program to read a file in serial way, and reverse the contents of the employee record and then, again traverse and read the record in the newly reversed file.Suppose a file “ABC.txt” contains three integers separated by commas. Write a program that use the existing file, read the integers and display them in reverse order separated by spaces. Secondly, get string input from user and append an existing file. Finally, count the number of words in a fileWrite a program that removes all the occurrences of a specified string from a text file.Removes the string from the specified file. Your program should get the arguments from the command line.
