那你可以用c语言编写一个学生成绩管理系统吗 有数学 语文 英语 ，可以求每个学生的和，可以删除添加学生， 求最高分

是的，我可以用C语言编写一个学生成绩管理系统。下面是一个简单的实现，可以实现添加学生、删除学生、计算每个学生的总分、计算每个科目的最高分等功能。

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

#define MAX_NAME_LEN 20
#define MAX_STUDENT_NUM 100

typedef struct student {
    char name[MAX_NAME_LEN];
    int math_score;
    int chinese_score;
    int english_score;
} Student;

Student students[MAX_STUDENT_NUM];
int student_count = 0;

void add_student() {
    if (student_count >= MAX_STUDENT_NUM) {
        printf("Too many students!\n");
        return;
    }
    Student new_student;
    printf("Please enter the name of the student: ");
    scanf("%s", new_student.name);
    printf("Please enter the math score of the student: ");
    scanf("%d", &new_student.math_score);
    printf("Please enter the Chinese score of the student: ");
    scanf("%d", &new_student.chinese_score);
    printf("Please enter the English score of the student: ");
    scanf("%d", &new_student.english_score);
    students[student_count++] = new_student;
    printf("Student added successfully!\n");
}

void delete_student() {
    char name[MAX_NAME_LEN];
    printf("Please enter the name of the student you want to delete: ");
    scanf("%s", name);
    int found = 0;
    for (int i = 0; i < student_count; i++) {
        if (strcmp(students[i].name, name) == 0) {
            found = 1;
            for (int j = i; j < student_count - 1; j++) {
                students[j] = students[j + 1];
            }
            student_count--;
            printf("Student deleted successfully!\n");
            break;
        }
    }
    if (!found) {
        printf("Student not found!\n");
    }
}

void print_student(Student student) {
    printf("%-10s%-10d%-10d%-10d\n", student.name, student.math_score, student.chinese_score, student.english_score);
}

void print_all_students() {
    printf("%-10s%-10s%-10s%-10s\n", "Name", "Math", "Chinese", "English");
    for (int i = 0; i < student_count; i++) {
        print_student(students[i]);
    }
}

int get_total_score(Student student) {
    return student.math_score + student.chinese_score + student.english_score;
}

void calculate_total_score() {
    printf("%-10s%-10s\n", "Name", "Total");
    for (int i = 0; i < student_count; i++) {
        printf("%-10s%-10d\n", students[i].name, get_total_score(students[i]));
    }
}

int get_max_score(int (*get_score)(Student)) {
    int max_score = -1;
    for (int i = 0; i < student_count; i++) {
        int score = get_score(students[i]);
        if (score > max_score) {
            max_score = score;
        }
    }
    return max_score;
}

void calculate_max_score() {
    printf("%-10s%-10d\n", "Math", get_max_score(&((int (*)(Student))get_total_score))));
    printf("%-10s%-10d\n", "Chinese", get_max_score(&((int (*)(Student))&students[0].chinese_score))));
    printf("%-10s%-10d\n", "English", get_max_score(&((int (*)(Student))&students[0].english_score))));
}

int main() {
    while (1) {
        printf("\n");
        printf("1. Add student\n");
        printf("2. Delete student\n");
        printf("3. Print all students\n");
        printf("4. Calculate total score\n");
        printf("5. Calculate max score\n");
        printf("6. Exit\n");
        printf("Please enter your choice: ");
        int choice;
        scanf("%d", &choice);
        switch (choice) {
            case 1:
                add_student();
                break;
            case 2:
                delete_student();
                break;
            case 3:
                print_all_students();
                break;
            case 4:
                calculate_total_score();
                break;
            case 5:
                calculate_max_score();
                break;
            case 6:
                exit(0);
            default:
                printf("Invalid choice!\n");
        }
    }
    return 0;
}

注意，这只是一个简单的实现，可能存在一些不足和漏洞。如果您需要更为完善的学生成绩管理系统，建议您根据自己的需求进行定制化开发。
