单链表学生成绩管理系统C语言代码

以下是一个简单的单链表学生成绩管理系统的C语言代码示例：

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

// 定义学生结构体
typedef struct Student {
    int id;
    char name[20];
    int score_chinese;
    int score_math;
    int score_english;
    int score_politics;
    int total_score;
    struct Student* next;
} Student;

// 创建学生节点
Student* createStudent(int id, char name[], int score_chinese, int score_math, int score_english, int score_politics) {
    Student* student = (Student*)malloc(sizeof(Student));
    student->id = id;
    strcpy(student->name, name);
    student->score_chinese = score_chinese;
    student->score_math = score_math;
    student->score_english = score_english;
    student->score_politics = score_politics;
    student->total_score = score_chinese + score_math + score_english + score_politics;
    student->next = NULL;
    return student;
}

// 插入学生节点
void insertStudent(Student** head, Student* student) {
    if (*head == NULL) {
        *head = student;
    } else {
        Student* current = *head;
        while (current->next != NULL) {
            current = current->next;
        }
        current->next = student;
    }
}

// 打印学生信息
void printStudent(Student* student) {
    printf("学号：%d\n", student->id);
    printf("姓名：%s\n", student->name);
    printf("语文成绩：%d\n", student->score_chinese);
    printf("数学成绩：%d\n", student->score_math);
    printf("英语成绩：%d\n", student->score_english);
    printf("政治成绩：%d\n", student->score_politics);
    printf("总分：%d\n", student->total_score);
    printf("\n");
}

// 遍历打印学生链表
void printStudentList(Student* head) {
    Student* current = head;    while (current != NULL) {
        printStudent(current);
        current = current->next;
    }
}

int main() {
    Student* head = NULL;

    // 添加学生节点
    Student* student1 = createStudent(1, "张三", 80, 90, 85, 75);
    insertStudent(&head, student1);

    Student* student2 = createStudent(2, "李四", 75, 85, 90, 80);
    insertStudent(&head, student2);

    Student* student3 = createStudent(3, "王五", 90, 80, 95, 85);
    insertStudent(&head, student3);

    // 打印学生链表
    printStudentList(head);

    return 0;
}
