c -在链表中输入字符变量

Question

我必须用链表制作学生数据库，但是在输入第一个学生的信息后，我不能输入其他学生的名字。

struct Student
{
    char name[20];
    int egn;
struct Student *next;
}*start=NULL;

void creat()
{
char ch;
do
{
struct Student *newStudent,*current;
newStudent=(struct Student *)malloc(sizeof(struct Student));
    printf("nEnter student's name: ");
    gets(newStudent->name);
    printf("Enter student's egn: ");
    scanf("%d",&newStudent->egn);
    newStudent->next=NULL;
if(start==NULL)
{
start=newStudent;
current=newStudent;
}
else
{
current->next=newStudent;
current=newStudent;
}
printf("nDo you want to creat another : ");
ch=getche();
}while(ch!='n');
}

和结果:

Enter student's name: First Student
Enter student's egn: 234234
Do you want to creat another : y
Enter student's name: Enter student's egn: 23452342
Do you want to creat another : y
Enter student's name: Enter student's egn: 234234
Do you want to creat another : n

我错在哪里?

Answer 1

尝试在gets(newStudent->name)之前和之后使用fflush(stdin);声明
