Thread: Accessing elements in an array of pointers to arrays

I have an array of pointers that point to arrays of characters and what I'd like to do is access the 4th letter in the 3rd word and change it. I've tried tons of combinations but I can't seem to get a pointer to what I want, any suggestions. Thanks. PS I know the code doesn't print anything out yet.

Code:

int main()
{
   char *words[] = {"One", "Two", "Three", "Four"};
   (*words[2]) + 3 = 'D'; //I'd like to turn the 1st 'e' in Three into a D
   return 0;
}

Those are both incorrect (for me anyways) and all give segmentation fault errors. I even tried changing char *words[] to char **words[] and I just get different errors using that.

Initialized char *s are constant and cannot be modified. The string is loaded into read-only memory.

Maybe what you want is more like:

Code:

int main()
{
  int i;
  char words[4][6] = {{"One"}, {"Two"}, {"Three"}, {"Four"}};
  (words[2][3] = 'D'; //I'd like to turn the 1st 'e' in Three into a D

  for(i=0;i<4;i++)
    printf("\n %s", words[i]);

   return 0;
}
