    Talking no redirection

    hi, this is my first post here. you came highly recommended i am doing a project for homework that deals with hashing, but i am getting caught up on something that i don't think is supposed to be that big of a problem.

    it requires the names of 6 files to be scanned in. I know how to do this after the program is running, but the catch here is that the names are being put in directly after the a.out.

    i've gotten the program to work if i type a.out, hit enter, then enter the name of the file. but if i type the name of the file before hitting enter, it won't work.

    so, its supposed to be put in like this :
    Code:
    $ a.out file1 delete1 ans1 ans2 ans4 ans5

    Code:
    #include <stdio.h>
    
    int main(int argc, char *argv[])
    {
       if ( argc < 2 )
       {
          puts("input filenames here");
       }
       else
       {
          int i;
          puts("filenames from command line:");
          for ( i = 1; i < argc; ++i )
          {
             puts(argv[i]);
          }
       }
       return 0;    
    }
