Write A C program

Objectives Working with files Reading from a file Writing to a file

Scenario Write a program that copies itself and adds line numbers to each line. You can (for now, to simplify your task, of course) assume constant file names. First, open the file in read mode, then open the copy file in write mode. After that, line by line, get the lines from the source file, append the number of the line to the destination file, and append the line content. Remember to close both files. Note: in a real program, it's important to check whether all the needed files exist and that you can create a copy. In our program, you should at least check that both files have been successfully opened. If one of the fopen functions fails, then print the message: "Error opening a file." and end the program.

#include int main() {

/* your code */

return 0; }

Example output Copy of source file with line numbers.
