为什么第一个name不能输入？

运行后第一个name不能输入数据（直接跳过了），还有输出的结果也不对（number>2）时
#include<stdio.h>
#include<stdlib.h>
#include<string.h>
#define LEN sizeof(struct linkinfo)

struct linkinfo
{
char name[20];
char place[128];
char birthday[10];
char telephone[16];
struct linkinfo *next;
};

struct linkinfo *create(int number)
{
struct linkinfo *new,*head = NULL,*tail = NULL;
int i,count = 0;
for(i=0; i<number; i++)
{
new = (struct linkinfo *)malloc(LEN);
printf("name：");
gets(new->name); //改为scanf("%s",new->name);就行，但是scanf不能输入空格和空数据
printf("\n%s",new->name);
printf("place：");
scanf("%s",new->place);
printf("birthday：");
scanf("%s",new->birthday);
printf("tel：");
scanf("%s",new->telephone);
count++;
new->next = NULL;
if(count <= 1)
{
head = new;
}
else
{
tail->next = new;
}
tail = new;
}
return (head);
}

main()
{
struct linkinfo *p_main;
int i,number;
printf("number：");
scanf("%d",&number);
p_main = create(number);
for(i=0; i<number; i++,p_main = p_main->next)
{
printf("%s\n",p_main->name);
printf("%s\n",p_main->place);
printf("%s\n",p_main->birthday);
printf("%s\n",p_main->telephone);
}
}

在gets(new->)前的printf("name:");的上面加一句：fflush(stdin);即可，该句将标准输入缓冲区清除，运行通过，修改后代码如下：
#include<stdio.h>
#include<stdlib.h>
#include<string.h>
#define LEN sizeof(struct linkinfo)

struct linkinfo
{
char name[20];
char place[128];
char birthday[10];
char telephone[16];
struct linkinfo *next;
};

struct linkinfo *create(int number)
{
struct linkinfo *new,*head = NULL,*tail = NULL;
int i,count = 0;
for(i=0; i<number; i++)
{
new = (struct linkinfo *)malloc(LEN);
fflush(stdin);
printf("name：");
gets(new->name);
printf("place：");
scanf("%s",new->place);
printf("birthday：");
scanf("%s",new->birthday);
printf("tel：");
scanf("%s",new->telephone);
count++;
new->next = NULL;
if(count <= 1)
{
head = new;
}
else
{
tail->next = new;
}
tail = new;
}
return (head);
}

main()
{
struct linkinfo *p_main;
int i,number;
printf("number：");
scanf("%d",&number);
p_main = create(number);
for(i=0; i<number; i++,p_main = p_main->next)
{
printf("Name:%s\n",p_main->name);
printf("Place:%s\n",p_main->place);
printf("Birthday:%s\n",p_main->birthday);
printf("Tel:%s\n",p_main->telephone);
}
while(!kbhit());
return 0;
}
另外再说一句，假设你的程序中第一个NUMBER输入为非数字时可能出现问题，应限定条件加以预防。
