学霸君一对一辅导价格:c程序的malloc问题

来源:百度文库 编辑:查人人中国名人网 时间:2024/05/03 02:56:17
程序如下:
#include<malloc.h>
#define NULL 0
#define LEN sizeof(struct student)
struct student
{
long num;
float score;
struct student *next;
};
int n;
struct student *creat(void)
{
struct student *head;
struct student *p1,*p2;
n=0;
p1=p2=(struct student *)malloc(LEN);
scanf("%ld,%f",&p1->num,&p1->score);
head=NULL;
while(p1->num!=0)
{n=n+1;
if(n==!)head=p1);
else p2->next=p1;
p2=p1;
p1=(struct student *)malloc(LEN);
scanf("ld,%f",&p1->num,&p1->score);
}
p2->=NULL;
return(head);
}
main()
{
creat();
}
这是书本上的一个例子,检查了n次,确实如书上一字不错地输入。可是当运行时,提示是:Unable to open include file ‘MALLOC.H',请问是怎么回事,
