代码如下，如有帮助，请采纳一下，谢谢。

#include <stdio.h>
#include <string.h>
struct data
{
	int year;
	int month;
	int day;
};
struct stu
{
	int num;
	char name[20];
	char sex;
	struct data birth;
	float score;
};
int main()
{
	struct stu s1 = {10010,"zhangsan",'m',2000,5,4,84.5},s2,s3;
	printf("请输入学生2的学号：");
	scanf("%d",&s2.num);
	printf("请输入写生2的姓名：");
	scanf("%s",s2.name);
	printf("请输入学生2的性别：");
	scanf(" %c",&s2.sex);
	printf("请输入学生2的生日：");
	scanf("%d %d %d",&s2.birth.year,&s2.birth.month,&s2.birth.day);
	printf("请输入学生2的成绩：");
	scanf("%f",&s2.score);
	//交换
	s3 = s1;
	s1 = s2;
	s2 = s3;
	//输出s1和s2
	printf("学号：%d\n",s1.num);
	printf("姓名：%s\n",s1.name);
	printf("性别：%c\n",s1.sex);
	printf("出生日期：%d年%d月%d日\n",s1.birth.year,s1.birth.month,s1.birth.day);
	printf("成绩：%g\n",s1.score);
	printf("学号：%d\n",s2.num);
	printf("姓名：%s\n",s2.name);
	printf("性别：%c\n",s2.sex);
	printf("出生日期：%d年%d月%d日\n",s2.birth.year,s2.birth.month,s2.birth.day);
	printf("成绩：%g\n",s2.score);
	return 0;
