用array去展示5个不同的char

我想通过一个array去展示5个不同的学生，也就是这个array里面需要=5

这是头文件的代码
#define MAXSIZE   25

typedef struct studentId
{
    int studentnum;
    
}STUDENTID;
typedef struct studentName
{
    char firstname[MAXSIZE];
    char lasttname[MAXSIZE];
    char middelname[MAXSIZE];
}STUDENTNAME;

STUDENTID CreatestudentId(int);
STUDENTNAME CreatestudentName(char[], char[], char[]);
void printstudent(STUDENT);

这是c文件的代码

#define _CRT_SECURE_NO_WARNINGS
#include"student.h"
#include
#include
#define FiveStudentName  5

STUDENTID CreatestudentId(int StudentNum)
{
    STUDENTID n;
    n.studentnum = StudentNum;
    return n;
}


STUDENTNAME CreatestudentName(char lasttname[MAXSIZE], char firstname[MAXSIZE], char middelname[MAXSIZE])
{
    STUDENTNAME s;
    strncpy(s.lasttname, lasttname, MAXSIZE);
    strncpy(s.firstname, firstname, MAXSIZE);
    strncpy(s.middelname, middelname, MAXSIZE);

    return s;
}

//print the student id
void printstudentId(STUDENTID student)
{

    printf("%d-", student.studentnum);
}

//priint the studet Name
void printstudentName(STUDENTNAME student)
{
    STUDENTNAME arrayname[FiveStudentName] = {printstudentName};
    printf("%s，%s",student.lasttname, student.firstname); 
    if (student.middelname[0] != '\0') // this mean nothing on middlename
        printf(" %c", student.middelname[0]);
}

这是main.c的代码
int main()
{
    // student 1
    printf("student 1\n");
    STUDENTID luxId = CreatestudentId(2003056789);
    STUDENTNAME luxName = CreatestudentName("lux", "Juntig", "Ren");
    //printf("NAME：%s\n", GetNameFromStudent(lux));
    printstudentId(luxId);
    printstudentName(luxName);
    printf("\n");

    // student 2
    printf("student 2\n");
    STUDENTID BaronId = CreatestudentId(2004069876);
    STUDENTNAME BaronName = CreatestudentName("Baron", "Asa", "");
    // printf("NAME：%s\n", GetNameFromStudent(a));
    printstudentId(BaronId);
    printstudentName(BaronName);
    printf("\n");

    // student 3
    printf("student 3\n");
    STUDENTID ArnoId = CreatestudentId(2003081234);
    STUDENTNAME ArnoName = CreatestudentName("Arno", "Barry", "Bart");
    // printf("NAME：%s\n", GetNameFromStudent(b));
    printstudentId(ArnoId);
    printstudentName(ArnoName);
    printf("\n");

    // student 4
    printf("student 4\n");
    STUDENTID BartonId = CreatestudentId(2003074521);
    STUDENTNAME BartonName = CreatestudentName("Barton", "Bing", "");
    // printf("NAME：%s\n", GetNameFromStudent(c));
    printstudentId(BartonId);
    printstudentName(BartonName);
    printf("\n");

    // student 5
    printf("student 5\n");
    STUDENTID BillId = CreatestudentId(2003017623);
    STUDENTNAME BillName = CreatestudentName("Bill", "Black", "Blithe");
    // printf("NAME：%s\n", GetNameFromStudent(d));
    printstudentId(BillId);
    printstudentName(BillName);
    return 0;
}

你要说明白你遇到了啥问题啊，编译报错？运行结果不对？？？

这是头文件的代码
#define MAXSIZE   25
typedef struct _student
{
    int studentnum;   
    char firstname[MAXSIZE];
    char lasttname[MAXSIZE];
    char middelname[MAXSIZE];
}student;

void printstudent(student *stu,int n);
这是c文件的代码
#define _CRT_SECURE_NO_WARNINGS
#include"student.h"
#include <stdio.h>
#include <stdlib.h>
#define FiveStudentName  5
 
void printstudent(student * stu, int n)
{
    for(int i=0;i<n;i++)
    {
        if(stu[i].middelname[0] == '\0')
            printf("%d - %s,%s\n",stu[i].studentnum,stu[i].lasttname,stu[i].firstname);
        else
            printf("%d - %s,%s %c\n",stu[i].studentnum,stu[i].lasttname,stu[i].firstname,stu[i].middelname[0]);
    }
}

这是main.c的代码
int main()
{
    student stu[FiveStudentName] = {{2003056789,"lux", "Juntig", "Ren"},{2004069876,"Baron", "Asa", ""},{2003081234,"Arno", "Barry", "Bart"},{2003074521,"Barton", "Bing", ""},{2003017623,"Bill", "Black", "Blithe"}};
    printstudent(stu,FiveStudentName);
    return 0;
}
 

这样的吗，把你贴的代码改了一下

//这是头文件的代码
#define MAXSIZE   25
typedef struct studentId
{
    int studentnum;
}STUDENTID;
typedef struct studentName
{
    char firstname[MAXSIZE];
    char lasttname[MAXSIZE];
    char middelname[MAXSIZE];
}STUDENTNAME;

//这是c文件的代码
STUDENTID CreatestudentId(int);
STUDENTNAME CreatestudentName(char[], char[], char[]);
void printstudent(STUDENTID);

#define _CRT_SECURE_NO_WARNINGS
//#include"student.h"
#include <string.h>
#include <stdio.h>
#define FiveStudentName  5
STUDENTID CreatestudentId(int StudentNum)
{
    STUDENTID n;
    n.studentnum = StudentNum;
    return n;
}
STUDENTNAME CreatestudentName(char lasttname[MAXSIZE], char firstname[MAXSIZE], char middelname[MAXSIZE])
{
    STUDENTNAME s;
    strncpy(s.lasttname, lasttname, MAXSIZE);
    strncpy(s.firstname, firstname, MAXSIZE);
    strncpy(s.middelname, middelname, MAXSIZE);
    return s;
}
//print the student id
void printstudentId(STUDENTID student)
{
    printf("%d-", student.studentnum);
}
//priint the studet Name
void printstudentName(STUDENTNAME student)
{
    STUDENTNAME arrayname[FiveStudentName] = {"printstudentName"};
    printf("%s，%s",student.lasttname, student.firstname); 
    if (student.middelname[0] != '\0') // this mean nothing on middlename
        printf(" %c", student.middelname[0]);
}
//这是main.c的代码
//include 
int main()
{
    // student 1
    printf("student 1\n");
    STUDENTID luxId = CreatestudentId(2003056789);
    STUDENTNAME luxName = CreatestudentName("lux", "Juntig", "Ren");
    //printf("NAME：%s\n", GetNameFromStudent(lux));
    printstudentId(luxId);
    printstudentName(luxName);
    printf("\n");
    // student 2
    printf("student 2\n");
    STUDENTID BaronId = CreatestudentId(2004069876);
    STUDENTNAME BaronName = CreatestudentName("Baron", "Asa", "");
    // printf("NAME：%s\n", GetNameFromStudent(a));
    printstudentId(BaronId);
    printstudentName(BaronName);
    printf("\n");
    // student 3
    printf("student 3\n");
    STUDENTID ArnoId = CreatestudentId(2003081234);
    STUDENTNAME ArnoName = CreatestudentName("Arno", "Barry", "Bart");
    // printf("NAME：%s\n", GetNameFromStudent(b));
    printstudentId(ArnoId);
    printstudentName(ArnoName);
    printf("\n");
    // student 4
    printf("student 4\n");
    STUDENTID BartonId = CreatestudentId(2003074521);
    STUDENTNAME BartonName = CreatestudentName("Barton", "Bing", "");
    // printf("NAME：%s\n", GetNameFromStudent(c));
    printstudentId(BartonId);
    printstudentName(BartonName);
    printf("\n");
    // student 5
    printf("student 5\n");
    STUDENTID BillId = CreatestudentId(2003017623);
    STUDENTNAME BillName = CreatestudentName("Bill", "Black", "Blithe");
    // printf("NAME：%s\n", GetNameFromStudent(d));
    printstudentId(BillId);
    printstudentName(BillName);
    return 0;
}

那你到是声明一个数组呀
搞一堆变量是在干啥
你好歹得有个结构体把studentId和studentName放一起吧，这么一堆散装变量怎么放数组里呀

题目是什么，私发我帮你写了
