    Regex Pattern Question

    I'm working on a regex parser that sifts through an input file and matches a student's name to their grade.

    Code:
    char name[BUF_SIZE];
    
    sprintf(name,argv[2]);     /*copy netid into name */
    printf("Grade Info For '%s'\n\n",name);
    
    sprintf(name_grade, "(\\-.[char name goes here]).\\|.([0-9]+)");
    How can I get the 2nd sprintf line to regex match on the name stored in char name[] ?

    The file input format is

    Code:
     - studentname | 29
    Thanks

    So if the given argument has name "bob", the regex should look like "- bob | ([0-9])+"?

    Why dont you just print it?
    Code:
    sprintf(name_grade, "(\\-.%s).\\|.([0-9]+)", name);
    Or whatever format it is--just use it as if you were "printf"ing.

    No problem. Keep in mind that "sprintf" and "fprintf" are the string- and file-output equivalents of screen-output "printf", respectively. So anything you can do in "printf", is just as easily done in the other functions.
