How do you determine if a file or directory name just read into the dirent struct is a directory?
Can you help/guide me on this assignment, here are the directions:
Write a program that reads words from a text file and displays all the words (duplicates allowed) in ascending alphabetical order. The words must start with a letter. The text file is passed as command-line argument (you can assume that the text file is in the same directory as the executable, i.e. bin).
I think the code is correct but I believe what I'm doing wrong is the Command line argument where I'm placing the text file. Which I think is in the right place, apparently not.
Here's my work:
Your ReadRoomFile program reads a room file. Is it possible to tell how many rooms are in the file from the file size? Explain why or why not?
