Can a pointer to a string be used in a printf?

I am thinking of something like:

#include <stdio.h>
#include <conio.h>
#include <stdlib.h>

int main(void) {
    //test pointer to string
    char s[50];
    char *ptr=s;
    printf("\nEnter string (s): ");
    fgets(s, 50, stdin);
    printf("S: %s\nPTR: %s\n", s, *ptr);

    system("PAUSE");
    return 0;
}

Or should I use a for loop with *(s+i) and the format specifier %c? Is that the only possible way to print a string through a pointer and a simple printf?

Update: The printf operates with the adress of the first element of the array so when I use *ptr I actually operate with the first element and not it's adress. Thanks.
