C/C++单链表实现简易队员信息管理系统：添加、删除、查找、修改

本系统使用C/C++语言实现单链表，提供添加、删除、查找、修改队员信息的功能，并采用分文件编程方式，提高代码可读性和可维护性。

队员信息

每位队员的信息包括：

编号
姓名
年龄
电话号码

基本任务

添加队员
删除队员
按照姓名（要处理重名问题）查找队员
修改队员信息
显示所有联系人信息

代码要求

建项目分文件编写（三个）

test.c			//测试程序……
TeamMembers.c	//放功能函数的实现……
TeamMembers.h	//放头文件、函数声明……

变量、函数名命名规范（驼峰命名法）
要有基本的功能选择界面内容

代码示例

TeamMembers.h

#ifndef TEAM_MEMBERS_H
#define TEAM_MEMBERS_H

typedef struct {
    int id;
    char name[20];
    int age;
    char phone[15];
} Member;

void addMember(Member *members, int *count);
void deleteMember(Member *members, int *count);
void searchMember(Member *members, int count);
void modifyMember(Member *members, int count);
void displayMembers(Member *members, int count);

#endif

TeamMembers.c

#include <stdio.h>
#include <string.h>
#include "TeamMembers.h"

void addMember(Member *members, int *count) {
    printf("Enter the member's information:\n");

    scanf("%s", members[*count].name);

        if (strcmp(members[i].name, name) == 0) {
            printf("ID: %d\n", members[i].id);
            printf("Name: %s\n", members[i].name);

        printf("No members found.\n");
    }
}

void modifyMember(Member *members, int count) {
    int id, i;
    printf("Enter the ID of the member you want to modify: ");
    scanf("%d", &id);

            printf("Member modified successfully!\n");
            return;

    }

    printf("Member not found.\n");

void displayMembers(Member *members, int count) {
    int i;
    printf("All members:\n");
    for (i = 0; i < count; i++) {

test.c

#include <stdio.h>
#include "TeamMembers.h"

#define MAX_MEMBERS 100

int main() {
    Member members[MAX_MEMBERS];
    int count = 0;
    int choice;

    do {
        printf("=============== Team Member Management ===============
");
        printf("1. Add Member\n");
        printf("2. Delete Member\n");
        printf("3. Search Member\n");
        printf("4. Modify Member\n");
        printf("5. Display Members\n");
        printf("0. Exit\n");
        printf("======================================================\n");
        printf("Enter your choice: ");
        scanf("%d", &choice);

        switch (choice) {
            case 1:
                addMember(members, &count);
                break;
            case 2:
                deleteMember(members, &count);
                break;
            case 3:
                searchMember(members, count);
                break;
            case 4:
                modifyMember(members, count);
                break;
            case 5:
                displayMembers(members, count);
                break;
            case 0:
                printf("Exiting...\n");
                break;
            default:
                printf("Invalid choice. Please try again.\n");
        }
    } while (choice != 0);

    return 0;
}

说明

在此示例中，我们使用了一个Member结构体来表示每个队员的信息，包括编号、姓名、年龄和电话号码。TeamMembers.h中定义了各个功能函数的声明，TeamMembers.c中实现了这些功能函数，test.c中包含了一个简单的用户界面，通过输入选择执行不同的功能。可以根据需要添加更多的功能函数或进行其他修改。

注意：

本示例代码使用的是数组，为了实现单链表，需要修改代码，使用指针和动态内存分配。
该示例代码仅作为参考，具体的实现方式可以根据实际需求进行调整。

总结

本项目使用C/C++语言实现了一个简易的队员信息管理系统，并提供了添加、删除、查找、修改等基本功能。代码采用分文件编程方式，提高代码的可读性和可维护性。开发者可以根据实际需求对代码进行扩展和修改。
