C语言创建链表malloc的使用（C的创建对象）

struct student *creat(){struct student *head;struct student *p1, *p2;p1 = p2 = (struct student *)malloc(LEN);//LEN是student结构的大小 这就是new对象printf("Please enter the num :");scanf("%d", &p1->num);printf("Please enter the score :");scanf("%f", &p1->score);head = NULL;n = 0;while(0 != p1->num){n++;if(1 == n){head = p1;}else{p2->next = p1;}p2 = p1;p1 =  (struct student *)malloc(LEN);printf("Please enter the num :");scanf("%d", &p1->num);printf("Please enter the score :");scanf("%f", &p1->score);}p2->next = NULL;return head;}

#include <malloc.h>#include <stdlib.h>

记得这些头文件
