学生信息管理系统c语言

学生信息管理系统是一个比较常见的项目，可以用C语言来实现。以下是一个简单的C语言学生信息管理系统的示例代码，可以供您参考：

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

#define MAX_STUDENTS 100

struct student {
    char name[20];
    int age;
    char gender;
    int score;
};

struct student students[MAX_STUDENTS];
int num_students = 0;

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

    struct student s;
    printf("Enter student name: ");
    scanf("%s", s.name);
    printf("Enter student age: ");
    scanf("%d", &s.age);
    printf("Enter student gender (M/F): ");
    scanf(" %c", &s.gender);
    printf("Enter student score: ");
    scanf("%d", &s.score);

    students[num_students++] = s;

    printf("Student added.\n");
}

void display_student(struct student s) {
    printf("%s\t%d\t%c\t%d\n", s.name, s.age, s.gender, s.score);
}

void list_students() {
    printf("Name\tAge\tGender\tScore\n");
    for (int i = 0; i < num_students; i++) {
        display_student(students[i]);
    }
}

void search_student() {
    char name[20];
    printf("Enter student name: ");
    scanf("%s", name);

    for (int i = 0; i < num_students; i++) {
        if (strcmp(students[i].name, name) == 0) {
            display_student(students[i]);
            return;
        }
    }

    printf("Student not found.\n");
}

int main() {
    while (1) {
        printf("1. Add student\n");
        printf("2. List students\n");
        printf("3. Search student\n");
        printf("4. Quit\n");
        printf("Enter choice (1-4): ");

        int choice;
        scanf("%d", &choice);

        switch (choice) {
            case 1:
                add_student();
                break;
            case 2:
                list_students();
                break;
            case 3:
                search_student();
                break;
            case 4:
                printf("Goodbye!\n");
                exit(0);
            default:
                printf("Invalid choice.\n");
        }
    }

    return 0;
}

这个示例代码实现了一个简单的学生信息管理系统，可以进行添加学生、列出学生、搜索学生等操作。您可以根据自己的需求进行修改和扩展，以实现更为完整的学生信息管理系统。
