Reading from console window...

can someone help me figure out what i'm doing wrong here:
everything else works fine so i'm just giving parts of the code...
here's part of my main function:

Code:

---

int main(int argc, char* argv[])
{       
        char *fname;
       
        ifstream file;
        fname = argv[1];   
        aStarSearch.readFile(fname);  //function in a class which needs the argument to main from the console window
....
        return 0;
}

---

Here's part of the code from the readFile function:

Code:

---

void readFile(char *openfile)
{
          ifstream fin (openfile);
          while (! fin.eof() )
          {

          }
}

---

The problem is that when the console window open up, i can't type anything there...if i hardcode the name of the file to be opened it works fine but in that case the console window doesn't really come into play because it doesn't expect any inputs from the user...

am i using this wrong?

actually just checked and it's not accepting inputs in any case...i just used this code in main:

Code:

---

      int ix;
      for (ix = 0; ix < argc; ix++)
      printf("My %d. argument is %s\n", ix, argv[ix]);

---

and the console window just prints this out...so im guessing that's where you basically get your outputs and all...i was thinking more like the DOS thing...i give it some input and then i get output? do i have to run this using dos?

You do realise that nothing in your code actually asks for any input, right? All your code does is take whatever you put on the command line as the file name, and then it processes it. There is no user input, because you don't ever actually try to read anything from the user. You have no cin or scanf or whatever. It's only output and your file you specify on the command line.

You processing the argv is not getting input from the user. It's processing what is passed via the command line:

c:\mystuff\> filename commandlineargument

See?
