    Command Line Arguement

    hi

    I m creating a C++ program in Visual C++ 6.0 based on file handling!!

    What I want to do is, I want the user to mention the file name during the command line thing!!

    i..e if the user types: cl problem1 history.txt

    My program opens the history.txt file in reading mode.

    The thing is how do I, take this filename as arguement in my program!!

    thnx

    Search your help files for ARGV and ARGC... That'll point your nose in the right direction

    Step 1 - Learn to use google
    Step 2 - Learn C++

    Parsing out arguments given via the command line is usually one of the first few chapters of any book on c++ programming. Finding a tutorial on doing it should be trivial via google.
