c语言 调用函数中数组值传递问题

Question

#include<stdio.h>
#define N 3
typedef struct Student
{
    int num;
    char name[10];
    int score[3];
    float aver;
}Student;

void input(Student stu[]);
Student max(Student stu[]);
void print(Student stu[]);

int main()
{
    Student stu[N];
    Student *p=stu;
    Student q;
    input(p);
    q=max(p);
    /* printf("%d\n",q.score[1]); */ 

    print(q); 
    /*printf("学号%d\n  姓名%s\n  三门成绩%d %d %d\n 平均分%0.2f\n",
    q.num,  q.name,  q.score[0],   q.score[1],   q.score[2],   q.aver); */
    return 0;
}

void input(Student stu[])
{
    int i;
    for(i=0;i<3;i++)
    {

        scanf("%d %s %d %d %d",&stu[i].num,stu[i].name,&stu[i].score[0],&stu[i].score[1],&stu[i].score[2]);
        stu[i].aver=(stu[i].score[0]+stu[i].score[1]+stu[i].score[2])*1.0/3;
    }
   /*   printf("%d\n",stu[2].score[1]);  */
}


Student max(Student stu[])
{
    int i,m=0;
    for(i=0;i<N;i++)
    {
        if(stu[i].aver>stu[m].aver) m=i; 
    }
    /*printf("%d\n",stu[m].score[1]); */
    return stu[m];
  }


void print(Student stud)
{
    printf("成绩最高的同学是:\n");
    printf("学号%d\n  姓名%s\n  三门成绩%0.2f %0.2f %0.2f\n 平均分%0.2f\n",
    stud.num,stud.name,stud.score[0],stud.score[1],stud.score[2],
    stud.aver); 
}

c:\users\初晨陌夜\desktop\s.cpp(24) : error C2664: 'print' : cannot convert parameter 1 from 'struct Student' to 'struct Student []' 求指教

建议这样改：

#include "pch.h"
#include <iostream>
using namespace std;
#include<stdio.h>
#define N 3
typedef struct Student
{
    int num;
    char name[10];
    float score[3];
    float aver;
}Student;
void input(Student stu[]);
Student max(Student stu[]);
void print(Student stud);
int main()
{
    Student stu[N];
    Student *p = stu;
    Student q;
    input(p);
    q= max(p);
    /* printf("%d\n",q.score[1]); */

    print(q);
    /*printf("学号%d\n  姓名%s\n  三门成绩%d %d %d\n 平均分%0.2f\n",
    q.num,  q.name,  q.score[0],   q.score[1],   q.score[2],   q.aver); */
    return 0;
}

void input(Student stu[3])
{
    for ( int i = 0; i < 3; i++)
    {
        cout << "请输入第" << i + 1 << "个同学的学号：" << endl;
        scanf_s("%d", &stu[i].num);
        cout << "请输入第" << i + 1 << "个同学的名字：" << endl;
        scanf_s("%s", &stu[i].name, 10);
        cout << "请输入第" << i + 1 << "个同学的成绩：" << endl;
        for (int j = 0; j < 3; j++)
        {
            cout << "请输入第" << j << "次成绩：" << endl;
            scanf_s("%f", &stu[i].score[j]);
        }
        stu[i].aver = (stu[i].score[0] + stu[i].score[1] + stu[i].score[2])*1.0 / 3;
        cout << "第" << i + 1 << "个同学的平均分为：" << stu[i].aver << endl;

    }

}
Student max(Student stu[])
{
    int i, m = 0;
    for (i = 0; i < N; i++)
    {
        if (stu[i].aver > stu[m].aver) m = i;
    }
    /*printf("%d\n",stu[m].score[1]); */
    return stu[m];
}
void print(Student stud)
{
    printf("成绩最高的同学是:\n");
    printf("学号%d\n  姓名%s\n  三门成绩%0.2f %0.2f %0.2f\n 平均分%0.2f\n",
        stud.num, stud.name, stud.score[0], stud.score[1], stud.score[2],
        stud.aver);
}
