结构体类型变量的定义方法

#include <stdio.h>
struct Student
{
    int num;
    char name[20];
    char sex;
    int age;
    float score;
    char addr[30];
};
int main( )
{
    struct Student student1, student2;
    printf("%d\n", sizeof(student1));
    return 0;
}

使用了结构体类型的程序

#include <stdio.h>
struct Date
{
    int year;
    int month;
    int day;
};
int main()
{
    struct Date date;
    printf("input year,month,day: ");
    scanf("%d %d %d", &date.year, &date.month, &date.day);
    int days;
    days=……;
    　
    printf("%d月%d日是", date.month, date.day);
    printf("%d年的第%d天.\n", date.year, days);
    return 0;
}
