C语言实现后插

C语言实现后插 一、所需的知识。

1、数组

2、指针

二、代码展示。

#include
struct stu{
        int num;
        float score;
        struct stu *next;
};
struct stu a, b, c, *head;
void hou(){
a.num =1;
a.score = 89;
b.num = 2 ;
b.score = 98;
c.num = 3;
c.score = 99;
head = &a;
a.next = &b;
b.next = &c;
c.next = NULL;
do{
        printf("student number: %d score:%fn",head->num, head->score);
           head =        head->next; //head->next = head
}while(head); 
} 
int main(){
	hou();
	return 0;
} 

 三、总结。

本代码比较简单，不再过多讲解。
