C语言 利用指向结构体数组的指针将3个学生的全部信息输出

#include <stdio.h>
struct Student{
	int num;
	char name[20];
	char sex;
	int age;
};
struct Student stu[3]={{10101,"Li Lin",'M',18},{10102,"Zhang Fang",'M',19},{10104,"Wang Min",'F',20}};
int main(){
	struct Student *p;
	printf("No.   Name                sex age\n");
	for(p=stu;p<stu+3;p++)
		printf("%5d %-20s%2c%4d\n",p->num,p->name,p->sex,p->age);
	return 0;
}
