下面是一个基于C语言的示例代码,实现了按照学号递增排序和二分查找相应信息的功能。代码中使用了链表作为存储结构,每个节点包含学号、姓名和成绩信息。

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

// 定义学生结构体
typedef struct Student {
    int studentID;
    char name[50];
    int score;
    struct Student* next;
} Student;

// 创建新节点
Student* createNode(int studentID, char* name, int score) {
    Student* newNode = (Student*)malloc(sizeof(Student));
    newNode->studentID = studentID;
    strcpy(newNode->name, name);
    newNode->score = score;
    newNode->next = NULL;
    return newNode;
}

// 插入节点到链表
void insertNode(Student** head, Student* newNode) {
    if (*head == NULL || newNode->studentID < (*head)->studentID) {
        newNode->next = *head;
        *head = newNode;
    } else {
        Student* current = *head;
        while (current->next != NULL && current->next->studentID < newNode->studentID) {
            current = current->next;
        }
        newNode->next = current->next;
        current->next = newNode;
    }
}

// 按学号递增排序
void sortByStudentID(Student** head) {
    Student* sortedList = NULL;
    Student* current = *head;
    while (current != NULL) {
        Student* nextNode = current->next;
        insertNode(&sortedList, current);
        current = nextNode;
    }
    *head = sortedList;
}

// 二分查找学生信息
Student* binarySearch(Student* head, int studentID) {
    Student* left = head;
    Student* right = NULL;
    while (left != right) {
        Student* mid = left;
        int count = 0;
        while (mid != right) {
            mid = mid->next;
            count++;
        }
        int steps = count / 2;
        mid = left;
        while (steps > 0) {
            mid = mid->next;
            steps--;
        }
        if (mid->studentID < studentID) {
            left = mid->next;
        } else {
            right = mid;
        }
    }
    if (right != NULL && right->studentID == studentID) {
        return right;
    } else {
        return NULL;
    }
}

// 打印学生信息
void printStudent(Student* student) {
    if (student != NULL) {
        printf("学号:%d\n", student->studentID);
        printf("姓名:%s\n", student->name);
        printf("成绩:%d\n", student->score);
    } else {
        printf("未找到该学生信息\n");
    }
}

// 释放链表内存
void freeList(Student* head) {
    while (head != NULL) {
        Student* current = head;
        head = head->next;
        free(current);
    }
}

int main() {
    // 创建学生信息链表
    Student* head = NULL;
    insertNode(&head, createNode(102, "Alice", 85));
    insertNode(&head, createNode(104, "Bob", 92));
    insertNode(&head, createNode(103, "Charlie", 78));
    insert

Node(&head, createNode(101, "David", 90));

    // 按学号排序
    sortByStudentID(&head);

    // 二分查找学生信息
    int searchID = 103;
    Student* foundStudent = binarySearch(head, searchID);

    // 打印结果
    printStudent(foundStudent);

    // 释放链表内存
    freeList(head);

    return 0;
}

以上代码示例创建了一个学生信息的链表,并通过insertNode函数将学生节点按学号递增顺序插入链表中。然后,通过sortByStudentID函数对链表按学号进行排序。接着,使用binarySearch函数进行二分查找指定学号的学生信息,并通过printStudent函数打印查找结果。最后,使用freeList函数释放链表所占内存。
请根据你的实际需求将示例代码进行适当修改
