教材P233第9章课后习题题三(5):通讯录排序，试完成程序中空缺代码

【问题描述】教材P233第9章课后习题题三(5):通讯录排序，试完成程序中空缺代码。
【输入形式】输入整数n及n个人的基本信息。
【输出形式】输出按照年龄由大到小的排序结果。
【样例输入】：图片地址：http://10.81.10.7/userfiles/image/ch9_510.JPG
【样例说明】出生日期要求按照给定日期格式输入
补充下列代码：
#include"stdio.h"
#define N 10
struct Date
{ int year;
int month;
int day;
};
struct Mate
{ char name;

此处补充： ________________________________________

   char tel;
};
struct Mate classmate;
int Datecomp(struct Date d1,struct Date d2);//d1年龄比d2大返回1，相等返回0，小则返回-1
int main()
{ int i,j,k,n;
struct Mate m;
scanf("%d",&n);
for(i=0;i<n;i++) //输入n个同学的信息
{ scanf("%s",classmate.name);
      scanf("%d-%d-%d",&classmate.birthday.year,&classmate.birthday.month,&classmate.birthday.day);
      scanf("%s",classmate.tel);
   }
   for(i=0;i<n-1;i++) //按照年龄降序排列
   { k=i;

此处补充：______________________________________________

   if(k!=i)
      { m=classmate;
            classmate=classmate;
            classmate=m;
      }
   }
   for(i=0;i<n;i++)
      printf("name:%10s,%d-%d-%d,%12s\n",classmate.name,classmate.birthday.year,classmate.birthday.month,classmate.birthday.day,classmate.tel);
   return 0;
}

int Datecomp(struct Date d1,struct Date d2)
{

此处补充：________________________________________________

}

求助大佬！！！

用代码格式，我看得吃力的很{:10_291:}

大佬，貌似编译有点问题

我又忘了这个是C语言{:10_285:}

可恶的C++，我终于明白为什么C和C++是两种语言了{:10_250:}

zhangjinxuan 发表于 2022-12-9 20:44:26

现在问题解决了吗{:10_254:}
