The wordcount program gets the file names as command line arguments. It then creates n = argc - 1 child processes using fork() in a loop and expects each child process to count the number of words in each file. Basically, you need to first implement the the following code segment in wordcount. c. for(i=1; i < argc; i++) { if (fork() == 0) { // child process // call a function to count the number of words in file argv[i] // print the number of words in file argv[i] or error message if file argv[i] does not exist // return/exit with an exit code of 1 if the file argv[i] does not exist.
