指向结构的指针

#include <stdio.h>

int main ()
{
    struct user{
        char name[6];
        int age;
    };
    char *str = "qifei ,26";
    /* 1 */
    printf("qifei age:%s\n", &(((struct user *)(str))->age));
    /* 2 */
    struct user *p = (struct user *)(str);
    printf("qifei age:%s\n", &(p->age));
    return 0;
}
