C结构体：多种类型成员的访问

见码如见人：

 

#include <stdio.h>
//家庭
typedef struct
{
	char* father;
	char* mother;
} Family;
//学生
typedef struct
{
	int age;
	char* name;
	char* sex;
	char* title[2];
	Family* family;
} Student;

int main(int argc, char *argv[])
{
        //结构体赋值，成员可为空
	Student one = {10, "nick", "男",NULL};
	Student two = {};
	Student* twoPtr = &two;
	twoPtr->name = "bibi";
	printf("%s\n", two.name);

	//[[-----结构体成员的直接访问
	printf("%s\n", one.name);
	printf("%d\n", one.age);
	//--------]]
	//
	//[[----结构体成员的间接访问
	Student* p = &one;
	printf("one->age %d\n", p->age);
	printf("one.age %d\n", (*p).age);
	//--------]]
	//
	//[[-----成员为数组时的赋值与读取
	one.title[0] = "班长";
	printf("%s\n", one.title[0]);
	//-------]]
	
	//[[----成员为结构体时的赋值与读取
	// one.family->father = "老张";//不可行，未初始化结构体one.family时不可对成员赋值
	// one.family = &(Family){"老张", "老王"};//可行
	Family oneFamily = {"老张", "老王"};
	one.family = &oneFamily;
	printf("%s\n", p->family->father);
	//--------]]

	
    return 0;
