结构体

概念

开发者可以自定义的数据类型

定义结构体

struct House{
    char door[50];
    char window[50];
    char wall[50];
}

使用案例

#include <stdio.h>
struct House{
    char door[50];
    char window[50];
    char wall[50];
};
int main ()
{
    struct House house = {
        "铁门","玻璃窗","红砖墙"
    };
    printf("这个房子拥有 %s,%s,%s",house.door,house.window,house.wall);
    return 0;
}

#include <stdio.h>
struct House{
    char door[50];
    char window[50];
    char wall[50];
};
void descriptHouse(struct House house){
    printf("这个房子拥有%s,%s,%s\n",house.door,house.window,house.wall);
}
int main ()
{
    struct House house1 = {
        "铁门","铁窗","红砖墙"
    };
    struct House house2 = {
        "木门","木窗","木板墙"
    };
    struct House house3 = {
        "玻璃门","玻璃窗","黑砖墙"
    };
    descriptHouse(house1);
    descriptHouse(house2);
    descriptHouse(house3);

    return 0;
}

结构体与指针的应用案例

#include <stdio.h>
struct Person{
    int health;
    int satiety;
    
};

void toHospital(struct Person *p){
    p->health++;
}

void toRestaurant(struct Person *p){
    p->satiety++;
}

void feel(struct Person p){
    printf("i Feel health is %d , satiety is %d \n",p.health,p.satiety);
}

int main ()
{
    struct Person wangDaChui = {50,50};
    feel(wangDaChui);
    toHospital(&wangDaChui);
    toRestaurant(&wangDaChui);
    feel(wangDaChui);
    return 0;
}
