/定义学员结构体包括：学号(int)，姓名，成绩(float)，编写代码 (要求分函数实现) a) 创建多个学员数组并初始化 b) 添加一个学员，学号需要去重 c) 打印所有学员信息/采用单链表方式解决问题

这是一个关于编程的问题，可以回答。以下是参考代码：

#include <stdio.h>
#include <stdlib.h>
#include <string.h>

// 定义学员结构体
typedef struct Student {
    int id;
    char name[20];
    float score;
    struct Student *next;
} Student;

// 创建学员
Student *createStudent(int id, char *name, float score) {
    Student *s = (Student *)malloc(sizeof(Student));
    s->id = id;
    strcpy(s->name, name);
    s->score = score;
    s->next = NULL;
    return s;
}

// 添加学员
void addStudent(Student **pHead, Student *s) {
    if (*pHead == NULL) {
        *pHead = s;
        return;
    }

    Student *p = *pHead;
    while (p->next != NULL) {
        if (p->id == s->id) {
            printf("Duplicate id, please try again.\n");
            return;
        }
        p = p->next;
    }

    if (p->id == s->id) {
        printf("Duplicate id, please try again.\n");
        return;
    }

    p->next = s;
}

// 打印学员
void printStudent(Student *pHead) {
    Student *p = pHead;
    while (p != NULL) {
        printf("ID: %d, Name: %s, Score: %.1f\n", p->id, p->name, p->score);
        p = p->next;
    }
}

int main() {
    // 创建学员数组并初始化
    Student *s1 = createStudent(1, "Tom", 90.5);
    Student *s2 = createStudent(2, "Jerry", 85.0);
    Student *s3 = createStudent(3, "Bob", 92.5);
    Student *s4 = createStudent(4, "Alice", 88.0);
    Student *s5 = createStudent(5, "Lucy", 91.0);

    // 添加学员
    Student *pHead = NULL;
    addStudent(&pHead, s1);
    addStudent(&pHead, s2);
    addStudent(&pHead, s3);
    addStudent(&pHead, s4);
    addStudent(&pHead, s5);

    // 打印学员信息
    printStudent(pHead);

    return 0;
} 

此代码实现了对学员信息的添加和打印，采用了单链表方式解决问题。
