malloc?

person.c

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

struct person_t {
    char *name;
    int  age;
};

int main() {
    struct person_t *person;

    /* this, */
    person = malloc(sizeof person);

    /* or this? */
    person = calloc(1, sizeof *person);

    /* and why? */

    person->name = "pat";
    person->age  = 26;

    printf("%s is %i years old\n", person->name, person->age);

    free(person);
}

I think I shall not use calloc.
