学生综合素质测评系统c语言

学生综合素质测评系统的开发需要涉及到多个方面的知识，包括C语言基础、数据结构、算法、GUI等。下面是一个简单的学生综合素质测评系统的C语言代码示例，希望对您有所帮助：

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

#define MAX_SIZE 100

typedef struct student {
    char name[20];
    int id;
    float grade;
} Student;

void input_students(Student students[], int n);
void output_students(Student students[], int n);
void sort_students(Student students[], int n);
void find_student(Student students[], int n);

int main() {
    Student students[MAX_SIZE];
    int n, option;

    printf("请输入学生人数：");
    scanf("%d", &n);
    input_students(students, n);

    do {
        printf("\n请选择要执行的操作：\n");
        printf("1. 输出学生信息\n");
        printf("2. 按成绩排序\n");
        printf("3. 查找学生信息\n");
        printf("4. 退出程序\n");
        printf("请输入选项：");
        scanf("%d", &option);

        switch (option) {
            case 1:
                output_students(students, n);
                break;
            case 2:
                sort_students(students, n);
                break;
            case 3:
                find_student(students, n);
                break;
            case 4:
                printf("程序已退出！\n");
                break;
            default:
                printf("无效选项！\n");
                break;
        }
    } while (option != 4);

    return 0;
}

void input_students(Student students[], int n) {
    for (int i = 0; i < n; i++) {
        printf("请输入第%d位学生的姓名：", i + 1);
        scanf("%s", students[i].name);
        printf("请输入第%d位学生的学号：", i + 1);
        scanf("%d", &students[i].id);
        printf("请输入第%d位学生的成绩：", i + 1);
        scanf("%f", &students[i].grade);
    }
}

void output_students(Student students[], int n) {
    printf("学生姓名\t学号\t成绩\n");
    for (int i = 0; i < n; i++) {
        printf("%s\t\t%d\t%.2f\n", students[i].name, students[i].id, students[i].grade);
    }
}

void sort_students(Student students[], int n) {
    for (int i = 0; i < n - 1; i++) {
        for (int j = i + 1; j < n; j++) {
            if (students[i].grade < students[j].grade) {
                Student temp = students[i];
                students[i] = students[j];
                students[j] = temp;
            }
        }
    }
    printf("按成绩排序后的学生信息：\n");
    output_students(students, n);
}

void find_student(Student students[], int n) {
    char name[20];
    printf("请输入要查找的学生姓名：");
    scanf("%s", name);

    for (int i = 0; i < n; i++) {
        if (strcmp(students[i].name, name) == 0) {
            printf("学生姓名\t学号\t成绩\n");
            printf("%s\t\t%d\t%.2f\n", students[i].name, students[i].id, students[i].grade);
            return;
        }
    }
    printf("未找到该学生信息！\n");
}

这个示例代码实现了基本的学生信息输入、输出、排序和查找功能，您可以根据您的需求进行修改和扩展。
