結構體即我們自定義的資料型別，平時經常用到，結構體指標即將指標加入到一個型別中，理解結構體指標對學習指標可以進一步深入理解，並在連結串列等格式中運用非常廣泛，以下面程式舉例分析：

#include <stdio.h> 
#include <stdlib.h> 
#include <string.h> 

struct student{ 
char *name; 
int score; 
struct student* next; 
}; 
student stu;
student* stu1;
int main(){ 
stu.name = (char*)malloc(sizeof(char)); /*1.結構體成員指標需要初始化*/ 
strcpy(stu.name,"Jimy"); 
stu.score = 99; 

stu1 = (struct student*)malloc(sizeof(struct student));/*2.結構體指標需要初始化*/ 
stu1->name = (char*)malloc(sizeof(char));/*3.結構體指標的成員指標同樣需要初始化*/ 
stu.next = stu1; 
strcpy(stu1->name,"Lucy"); 
stu1->score = 98; 
stu1->next = NULL; 
printf("name %s, score %d \n ",stu.name, stu.score); 
printf("name %s, score %d \n ",stu1->name, stu1->score); 
free(stu1); 
return 0; 
}
