In this task, you’ll let your wordcount command read text from a regular file in addition to standard input (stdin). It involves using command-line arguments to specify the path to a file to read from. You’ll also ensure that your program can handle the dash (-) character as a special case to signify reading from standard input.
Acceptance Criteria
- Your program should read text from a file specified as a command-line argument and compute the count of lines, words, and bytes in it.
- If no command-line argument is provided, then your program should default to reading from standard input.
- The dash (
-) character as an argument should be treated as an indicator to read from standard input. - The output should display the counts of lines, words, and bytes, followed by the file name if reading from a regular file.
- The counts should be aligned and padded with spaces for readability as before.
