IMO, it's better not changing argv, if argv is the usual "main()" argv 
parameter.

If this isn't the case, argv shall have some memory allocated to it.

You can do, e.g. :

* char *argv[] = {"Good Morning", "Good Evening", NULL};

* char *argv[SOME_DIMENSION];
  char *line1="Good Morning";
  char *line2="Good Evening";
  argv[0] = line1;
  argv[1] = line2;

* char **argv;
  char *line1="Good Morning";
  char *line2="Good Evening";
  argv = (char **) malloc(SOME_DIMENSION * sizeof (*argv));
  argv[0] = line1;
  argv[1] = line2;
