1:编译运行都没问题的函数
#include<stdio.h>
#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<stdio.h>
#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]);
    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");
}

怎么解决赋值后在输入的问题？

求大虾帮忙？

着程序我VC6.0上可以运行的么

#include<stdlib.h>              //加入头文件                    //这是编译器搞得鬼
#include<stdio.h>
#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);
system("pause");        //加一句暂停
}
void print(struct student *p)
{
    printf(FORMAT,p->num,p->name,p->score[0],p->score[1],p->score[2]);
    printf("\n");
}

#include<stdio.h>
#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;
    scanf("%d%s%f%f%f",&stu.num,stu.name,&stu.score[0],&stu.score[1],&stu.score[2]);
    s = &stu;
    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");
}
先对stu赋初值后再赋给s就可以了
