C语言结构体赋值使用点号

#include "stdio.h"
int main()
{
    struct student{
        int age;
        int class_;
    };
    struct class2{
        struct student s1;
    };
    struct class2 *c;
    struct class2 cc={
    .s1={
        .age=9,
        .class_=2
    }
    };
    c=&cc;
    printf("%d",c->s1.age);
    return 0;
}
