一、举例说明：把下面的代码转换成工厂模式的方式来实现

#include <stdio.h>

struct Animal{

        char name[32];
        int eat;
        int age;
        int sex;
        void (*peat)();
};

void dogEat(){
        printf("dog chi shi\n");
}
void catEat(){
        printf("cat chi yu\n");
}
void personEat(){
        printf("person chi mi\n");
}

int main(){

        struct Animal dog = {
                .name = "a huang",
                .peat = dogEat
        };
        struct Animal cat = {
                .name = "a mao",
                .peat = catEat
        };
        struct Animal person = {
                .name = "a ren",
                .peat = personEat
        };

        dog.peat();
        cat.peat();
        person.peat();
        printf("%s\n",dog.name);
        return 0;
}
