Question

我必须使用链表创建学生数据库，但在输入第一名学生的信息后，我无法输入其他人的姓名。

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');
}

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

我的错误在哪里？

Answer 1

尝试在获取之前和之后使用fflush（stdin）（newStudent-＆gt; name）;声明

在链表中输入char变量
