在线等30分钟：c语言编程：能够输入100个学生的学号和姓名，并将。。。。。 已给出三个函数，求主函数。

//这个可以吗
#include

#define N 100
struct STUDENT
{
char id[20];
char name[20];
};
typedef struct STUDENT Student;

void inputdata(Student student[],int n);
void sort(Student student[],int n);
void search(Student student[],int n);

void main()
{

inputdata(student,N);
sort(student,N);
search(student,N);
}

printf("第%d个学生n",i+1);
printf("请输入学号:");
scanf("%s",student[i].id);
printf("请输入姓名");

//选择排序
void sort(Student student[],int n)
{

//折半查找
void search(Student student[],int n)
