#include <stdio.h>
#include <stdlib.h>
struct Date
{
  int year;
  int month;
  int day;
};
struct  Stu_Info
{
  char        no[9];
  char        name[20];
  char        sex;
  struct Date   birthday;
  unsigned int  classno;
  float        grade;
};
struct  Stu_Info  stu = {"20020306", "ZhangMing", 'M', {1986,12,10},1,90};
int main(void)
{
    printf("no=%d\n",stu.no);
    printf("name=%d\n",stu.name);
    printf("sex=%d\n",stu.sex);
    printf("birthday=%d\n",stu.birthday);
        printf("classno=%d\n",stu.classno);
    printf("grade=%d\n",stu.grade);
}

编译完输出为什么是这个结果？
no=134518688
name=134518697
sex=77
birthday=1986
grade=0
