我想在函数中实现输入2个值给结构体，但是为什么在输入数据运行之后是错误的。

用的是vc++6.0

# include <stdio.h>

void Input (struct Student*);
void Output (struct Student*);

struct Student
{
    int age;
    int score;
};

int main(void)
{
    struct Student stu;

    Input(&stu);
    Output(&stu);

    return 0;
}



void Input (struct Student * pstu)
{
    scanf ("%d", pstu->age);
    scanf ("%d", pstu->score);
}

void Output (struct Student * pstu)
{
    printf ("年龄：%d  ", pstu->age);
    printf ("成绩：%d\n", pstu->score);
}

scanf 要加取址符

 void Input (struct Student * pstu)
 {
     scanf ("%d", pstu->age);
     scanf ("%d", pstu->score);
 }

 void Output (struct Student * pstu)
 {
     printf ("年龄：%d  ", pstu->age);
     printf ("成绩：%d\n", pstu->score);


改成

 void Input (struct Student * pstu)
 {
     scanf ("%d", &pstu->age);
     scanf ("%d", &pstu->score);
 }

 void Output (struct Student * pstu)
 {
     printf ("年龄：%d  ", &pstu->age);
     printf ("成绩：%d\n", &pstu->score);

void Output (struct Student * pstu)
{
     printf ("年龄：%d  ", &pstu->age);
     printf ("成绩：%d\n", &pstu->score);           //这两个的&也要加么？

scanf传地址是因为要修改传入参数的值，所以要知道其位置

# include <stdio.h>
#include <iostream.h>
void Input (struct Student*);
void Output (struct Student*);

struct Student
{
    int age;
    int score;
};

int main(void)
{
    struct Student stu;
   
    Input(&stu);
    Output(&stu);
   
    return 0;
}



void Input (struct Student * pstu)
{   cin>>pstu->age;
    cin>>pstu->score;
    //scanf ("%d", &pstu->age);
    //scanf ("%d", &pstu->score);
}

void Output (struct Student * pstu)
{
    printf ("年龄：%d  ", pstu->age);
    printf ("成绩：%d\n", pstu->score);
 }

你也可以直接用c++的知识，那就没有这个问题了呀！！

# include <stdio.h>
#include <iostream.h>
void Input (struct Student*);
void Output (struct Student*);

struct Student
{
    int age;
    int score;
};

int main(void)
{
    struct Student stu;
   
    Input(&stu);
    Output(&stu);
   
    return 0;
}



void Input (struct Student * pstu)
{   cin>>pstu->age;
    cin>>pstu->score;
    //scanf ("%d", &pstu->age);
    //scanf ("%d", &pstu->score);
}

void Output (struct Student * pstu)
{
    printf ("年龄：%d  ", pstu->age);
    printf ("成绩：%d\n", pstu->score);
 }

    还是不够仔细啊！

谢谢，不过还没开始学那个~
