结构体字符串输入问题

1:编译运行都没问题的函数

#include
#define FORMAT "%d\n%s\n%f\n%f\n%f\n"

struct student
{
    int num;
    char name[20];
    float score[3];
};

struct student stu;

void main()
{
    void print(struct student *);
    scanf("%d%s%f%f%f",&stu.num,stu.name,&stu.score[0],&stu.score[1],&stu.score[2]);
    print(&stu);
    getch();
}

void print(struct student *p)
{
    printf(FORMAT,p->num,p->name,p->score[0],p->score[1],p->score[2]);
    printf("\n");
}
==================================================================================

2：编译能通过，但运行有问题

eg：输入：123 lili 89 89 89

    回车：控制台关闭。

    问题呢？

#include
#define FORMAT "%d\n%s\n%f\n%f\n%f\n"

struct student
{
    int num;
    char name[20];
    float score[3];
};

struct student stu;

void main()
{
    void print(struct student *);
    struct student *s;
    s = &stu;
    scanf("%d%s%f%f%f",&s->num,s->name,&s->score[0],&s->score[1],&s->score[2]);

/***

 **scanf("%d%s%f%f%f",&s.num,s.name,&s.score[0],&s.score[1],&s.score[2]);
 **此写法错误

***/
    print(s);
    getch();
}

void print(struct student *p)
{
    printf(FORMAT,p->num,p->name,p->score[0],p->score[1],p->score[2]);
    printf("\n");
}

 

===================================================================================

在vc上可以

在wintc上不能通过.

我晕。

===================================================================================

#define  NUM  4
/*#define  SUB_NUM 1      */

#include
#define FORMAT "%d\n%s\n%f\n%f\n%f\n"
struct student
{
    int num;
    char name[20];
    float score[3];
};
struct student stu[4];
void main()
{  
    int i;
    void print(struct student *);
    struct student *s;
    s = stu;
    for(i=0;i<4;i++){
        scanf("%d%s%f%f%f",&s->num,s->name,&s->score[0],&s->score[1],&s->score[2]);
        s++;
    }
    printf("\n");
    s = stu;
    for(i=0;i<4;i++){
        print(s);
        s++;
    }
    getch();
}
void print(struct student *p)
{
    printf(FORMAT,p->num,p->name,p->score[0],p->score[1],p->score[2]);
    printf("\n");
}
