学生综合测评系统源代码

抱歉，我无法直接提供完整的学生综合测评系统的源代码，因为这需要根据具体的需求和设计来编写。但是，我可以提供一个简单的示例代码，供您参考。

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

#define MAX_STUDENT_NUM 1000
#define MAX_NAME_LEN 20
#define MAX_SUBJECT_NUM 10

typedef struct {
    char name[MAX_NAME_LEN];
    int grade[MAX_SUBJECT_NUM];
    int total_grade;
    float avg_grade;
} Student;

int num_students = 0;
Student students[MAX_STUDENT_NUM];

void add_student() {
    if (num_students >= MAX_STUDENT_NUM) {
        printf("Error: too many students\n");
        return;
    }

    Student *s = &students[num_students];
    printf("Enter student name: ");
    scanf("%s", s->name);
    printf("Enter grades for %s:\n", s->name);
    for (int i = 0; i < MAX_SUBJECT_NUM; i++) {
        printf("Subject %d: ", i + 1);
        scanf("%d", &s->grade[i]);
        s->total_grade += s->grade[i];
    }
    s->avg_grade = (float) s->total_grade / MAX_SUBJECT_NUM;
    num_students++;
}

void print_student(Student *s) {
    printf("%s\t", s->name);
    for (int i = 0; i < MAX_SUBJECT_NUM; i++) {
        printf("%d\t", s->grade[i]);
    }
    printf("%d\t%.2f\n", s->total_grade, s->avg_grade);
}

void print_all_students() {
    printf("Name\t");
    for (int i = 0; i < MAX_SUBJECT_NUM; i++) {
        printf("Subject %d\t", i + 1);
    }
    printf("Total\tAverage\n");
    for (int i = 0; i < num_students; i++) {
        print_student(&students[i]);
    }
}

void search_student(char *name) {
    for (int i = 0; i < num_students; i++) {
        if (strcmp(name, students[i].name) == 0) {
            print_student(&students[i]);
            return;
        }
    }
    printf("Error: student not found\n");
}

void sort_students() {
    // simple bubble sort
    for (int i = 0; i < num_students; i++) {
        for (int j = i + 1; j < num_students; j++) {
            if (students[j].total_grade > students[i].total_grade) {
                Student temp = students[i];
                students[i] = students[j];
                students[j] = temp;
            }
        }
    }
}

int main() {
    int choice;
    while (1) {
        printf("\n");
        printf("1. Add student\n");
        printf("2. Print all students\n");
        printf("3. Search student\n");
        printf("4. Sort students\n");
        printf("5. Exit\n");
        printf("Enter your choice: ");
        scanf("%d", &choice);

        switch (choice) {
            case 1:
                add_student();
                break;
            case 2:
                print_all_students();
                break;
            case 3: {
                char name[MAX_NAME_LEN];
                printf("Enter student name: ");
                scanf("%s", name);
                search_student(name);
                break;
            }
            case 4:
                sort_students();
                printf("Students sorted by total grade:\n");
                print_all_students();
                break;
            case 5:
                exit(0);
            default:
                printf("Error: invalid choice\n");
                break;
        }
    }

    return 0;
}

这个示例代码实现了一个简单的学生综合测评系统，包括添加学生、打印所有学生、查询学生、排序学生等功能。当然，这只是一个简单的示例，实际的需求可能会更加复杂。如果您有具体的需求，可以根据示例代码进行修改和扩展。
