#include <stdio.h>

typedef struct dog{    结构体的定义
char name[20];
int num;
float weight;
}Dog;
int main(int argc, char const *argv[])
{
Dog dog[3]={0};
for (int i = 0; i < 3; ++i)
{
scanf("%s",dog[i].name);  数组本身是指针常量，记录首地址
scanf("%d",&dog[i].num);取地址，读
scanf("%f",&dog[i].weight);
}
for (int i = 0; i < 3; ++i)
{
printf("%s\n", dog[i].name);打印，不需要加取地址符&
printf("%d\n", dog[i].num);
printf("%.2f\n", dog[i].weight);
}

return 0;
}
