C-结构体的简单应用(10)

#include <stdio.h>

void test(){
	//1.定义结构体
	struct Student
	{
		char name[8];
		int age;
		int height;
	};//定义一个结构体
	//定义一个结构体对象,此时系统开始为该对象分配内存空间.
	struct Student stud={"linwb",25,171};
	printf("%u\n",sizeof(stud));//16 
	
	//2.对结构体进行存储
	stud.age=22;
	printf("%d\n",stud.age);
}

void test2(){
	//3.结构体数组
	struct MyStruct
	{
		int proper;
	} a[2]={{22},{23}};
	printf("%d",a[1].proper);
}

//结构体指针
void test3(){
	struct Student
	{
		char name[8];
		int age;
		int height;
	}stud={"lin",18,165};
	struct Student *p;
	p=&stud;
	stud.age;//1
	(*p).age;//2 间接取出age的值
	p->age;	//3
}

int main(int argc,char *argv[]){

	
	test3();
	

	return 0;
	
}
