    Hello all,

    I am developing an application using OpenCV that requires the user to specify the name of an image file, which then gets loaded using cvLoadImage ();

    cvLoadImage takes a (char *) as an argument- how do i have the user create one of these? the following code created a segfault:

    IplImage * img;
    char * filename;
    cin >> filename;
    img = cvLoadImage (filename);

    thanks!
