Thread: command line arguments

ok this deal with command line arguments is a bit weird and hard to understand.


basically I got the following code that isn't working, it's giving a
Segmentation Fault and I don't know why

Code:

  /* prints command line in reverse order */

  #include <stdio.h>

    main(int argc, char *argv[])
    {
      int i;
     for( i=argc ; i > 0; i-- )
         printf("%s\n", argv[i]);
  
      return i;
    }

wouldn't i=argc in loop (argc -which is the total # of arguments on command line)? then decrement to 0???

argc is the size of the array -- like all arrays, the last element is argc - 1.

Change to i = argc -1 and it will work.

Thanks V. that worked beautifully.
