Question

C语言问题，有关于结构体作为输入参数

大家帮忙看看为什么输入和输出不一样（如果不用函数，直接写的话运行是正确的,所以怀疑是结构体作为函数输入参数的时候出现了问题）

#include <stdio.h>

typedef struct {
char name[10];
char num[10];
int score;
} StudentStr;

void input(StudentStr student) {
printf("Name:");
scanf("%s", student.name);
printf("Number:");
scanf("%s", student.num);
printf("Score:");
scanf("%d",&student.score);
}

void output(StudentStr student) {
printf("Name: %s\n", student.name);
printf("Number: %s\n", student.num);
printf("Score: %d\n", student.score);
}

int main() {
StudentStr student[5];
input(student[1]);
output(student[1]);
return 0;
}

Answer 1

#include <stdio.h>

typedef struct
{
    char name[10];
    char num[10];
    int score;
} StudentStr;

void input(StudentStr *student)//<=============
{
    printf("Name:");
    scanf("%s", student->name);//<=============
    printf("Number:");
    scanf("%s", student->num);//<=============
    printf("Score:");
    scanf("%d", &student->score);//<=============
}

void output(StudentStr student)
{
    printf("Name: %s\n", student.name);
    printf("Number: %s\n", student.num);
    printf("Score: %d\n", student.score);
}

int main()
{
    StudentStr student[5];
    input(&student[1]);//<=============
    output(student[1]);
    return 0;
}

追问

谢谢，那麻烦再请问为什么输入和输出是不一样的呢
