改写代码中常见的错误

typedef struct student
｛
…
…
…
｝；struct student st[N];

void subject (student st[],int n)
函数调用时出现错误:unkown type name "student"
未知student类型名称
怎么改

typedef struct Student
{
  ...
}student;

student st[N];

这么用哈

第一个分号前加上student
typedef struct student
｛
…
…
…
｝student；
student st[N];

void subject (student st[],int n);

或者

#include<stdio.h>
#define N 10
struct student{

}student;
struct student st[N];
void subject (struct student st[],int n);

int main()
{
    printf("Hello world!");
    return 0;
}

void subject (struct student st[],int n)
类型要写全
或者在struct定义后面给struct取个别名
