Thread: command line arguments

I have a prog that reads in a file, manipulates it, and writes it to another file my command line details are
prog input.txt output.txt -m -u

my question is after i compile do i just type in prog input.txt output.txt -m -u or is there something else i need to do or a special way of compilling

You have to make the executable (prog.exe). What are the switches for? What shell are you using? Are they switches or does your program process them? As far as I can tell without seeing any code this much appears to look correct:

prog input.txt output.txt

Assuming you've written it correctly, yes, just invoke it as you've described:

myproggie file1 file2 arg1 arg2

Now, if you haven't written it correctly, this is how you do it:

Code:

int main ( int argc, char**argv )
{
   /**
   *** Do stuff here.
   **/
   int x;
   for(x=0;x<argc;x++) puts( argv[x] );
   return 0;
}
