Printing array of characters using printf

Is there a way I can print an array of characters using 'printf' in the following way (I know this isn't correct C code, I want to know if there is an alternative that will yield the same result).

printf("%s", {'h', 'e', 'l', 'l', 'o' });

How about a simple while loop? Assuming the array is null-terminated, of course. If not - you'll need to adjust to counting the number of characters in the array.

char a[] = {'h','e','l','l','o','\0'};
int i = 0;
while (a[i] != "\0")
{
   printf ("%c,", a[i]);
   i++;
}

Output:

h,e,l,l,o,

Note: do NOT try this on a char**! This is for char[] only!

This will work, but the length of the array must either be hard-coded in the format string or as a parameter or else the array must be defined twice (perhaps by one macro) so that its size can be calculated by the compiler:

printf("%.5s", (char []) {'h', 'e', 'l', 'l', 'o' });
