Write a C program that is given a file name as a command line argument. Open the file and read it. At the end of the file, print out: LINES: lc WORDS: wc CHARS: cc DIGITS: dc Where lc is the number of lines, wc is the number of words, cc is the number of characters, and dc is the number of digit characters, 0-9. If no file name is provided, the program should use the standard input instead of a file. If the file cannot be opened, print "CANNOT OPEN " followed by a space and the filename, and stop. The program should ignore any extra command line arguments that are provided after the file name.
