I would like to split a wchar_t string defined using pointer to its constituent wchar_t characters in C. i.e, if wchar_t *wcs = L"बहन" , then the output should be ब ह न

I tried the below 2 code snippets, but failed to get the desired output.

(1)

wchar_t *input = L"बहन";
int i=0;
while (input[i] != L'\0') {
      printf("i = %d : %lc\n",wcslen(input), input[i]);
      i++;
}

(2) In this approach I was not sure about what was to be used to split the string using the wcstok function. Hence, I gave the argument as L"".

wchar_t *input = L"बहन";
wchar_t *token;
wchar_t *state;
for (token = wcstok(input, L"", &state);token != NULL;token = wcstok(NULL, L"", &state)) {
        printf("Here %d: %s\n",wcslen(token),token);
    }

Do you need the `L` modifier on the `"बहन"` string? Do you need to use `wprintf()`? – Jonathan Leffler Sep 12 '15 at 07:12
`wcslen` returns a `size_t`; you should use the `%zu` format instead of `%d` to print it. – M Oehm Sep 12 '15 at 07:13
@JonathanLeffler: Sorry, it was in the correct format. I missed it out in the snippet while I wrote the snippet here. Thanks for pointing it out. – Anju Thomas Sep 12 '15 at 07:32
@MOehm: Tried %zu . But both %zu and %d are giving the same output. And what i need more importantly is the characters to be seperated out. – Anju Thomas Sep 12 '15 at 07:34
What output do you get from (1)? In what way is it wrong? – Alan Stokes Sep 12 '15 at 08:22
@AlanStokes: The output is: i = 3 : , i = 3 : It didn't loop thrice, and also its not printing the characters – Anju Thomas Sep 12 '15 at 09:43
