C语言结构体的引入

#include <stdio.h>

struct student{
    int ID;
    char name[48];
    int age;
};

int main(){
    //赋值：
    struct student s1 = { 1, "lifei", 24 };
    struct student s2 = { .ID = 2,.name="letben",.age = 28};
    struct student s3 = { 0, "qingwa", .ID = 3, .age = 25 };

    //使用：
    printf("%s\n", s1.name);
    printf("%d\n", s1.ID);
    printf("%d\n", s1.age);
    printf("二号同学的信息：id:%d,姓名：%s,年龄：%d\n", s2.ID, s2.name, s2.age);
    printf("三号同学的信息：id:%d,姓名：%s,年龄：%d\n", s3.ID, s3.name, s3.age);

    getchar();

    return 0;
