Why not incrementing z?

gistfile1.c

while(1) {		
  strcpy(fsm.state[x][z], lines[i]);
  printf("%i %i\n", x, z);
  z++; i++;
  if(strcmp(lines[i], ".") == 0) x++; z = 0;
  if(strcmp(lines[i], "") == 0) break;
}

Output is:

1 0
1 0
1 0
2 0
2 0
2 0
3 0
3 0
3 0

Need to have:

1 0
1 1
1 2
2 0
2 1
2 2
3 0
3 1
3 2

... etc ...
