大学生必备课设 - 通讯录系统 大学生必备课设第一弹来了，从今天开始我将会陆陆续续的分享一些大学生大一结束后可能老师要求的课程设计。这些内容都是当初我学习C/C++的时候写的代码。可以说还算宝贵把这些代码我全部在VS上面跑通了，如果有人转载的话 麻烦留下我博客的地址，十分感谢直接上代码和截图//菩提博客-大学生课设代码免费无偿分享 - 代码群 533683061 //作者：菩提科技 //官网：https://blog.wzl.icu //时间：2025-3-31 //Tips: 1.本代码仅供学习和研究使用，不得用于任何商业用途 // 2.本代码仅供大学生课设代码免费无偿分享，未经许可，不得转载 // 3.本代码如有侵权，请联系作者删除 // 4.最新代码发布在菩提博客，大家可以去那里下载！ // 5.代码是作者辛苦劳动的成果，如果对您有所帮助，希望您能在博客下点赞！采集或者转载请保留代码的地址，谢谢合作 //如有疑问请联系：https://blog.wzl.icu #include <iostream> #include <string> #include <vector> #include <algorithm> #define MAX 1000 using namespace std; //设计联系人结构体 struct Person { //姓名 string m_Name; //性别 int m_Sex; //年龄 int m_Age; //电话 string m_Phone; //住址 string m_Addr; }; //设计通讯录结构体 struct Addressbooks { //通讯录中保存的联系人数组 struct Person personArray[MAX]; int m_Size;//通讯录中人员个数 }; void showMean() { cout << "****************************" << endl; cout << "***** 1 添加联系人 *****" << endl; cout << "***** 2 显示联系人 *****" << endl; cout << "***** 3 删除联系人 *****" << endl; cout << "***** 4 查找联系人 *****" << endl; cout << "***** 5 修改联系人 *****" << endl; cout << "***** 6 清空联系人 *****" << endl; cout << "***** 0 退出通讯录 *****" << endl; cout << "******菩提博客版权所有******" << endl; } using namespace std; //添加联系人 void addPerson(Addressbooks* abs) { if (abs -> m_Size == MAX) { cout << "通讯录满了，无法添加" << endl; } else { //添加联系人 //姓名 string name; cout << "请输入姓名：" << endl; cin >> name; abs->personArray[abs->m_Size].m_Name = name; //性别 int Sex = 0; cout << "请输入性别：" << endl; cout << "1 --- 男" << endl; cout << "2 --- 女" << endl; while (true) { cin >> Sex; if (Sex == 1 || Sex == 2) { abs->personArray[abs->m_Size].m_Sex = Sex; break; } else { cout << "输入有误，请重新输入" << endl; } } //年龄 cout << "请输入年龄：" << endl; int age = 0; cin >> age; abs->personArray[abs->m_Size].m_Age = age; //电话 cout << "请输入电话：" << endl; string phone; cin >> phone; abs->personArray[abs->m_Size].m_Phone = phone; //住址 cout << "请输入住址：" << endl; string address; cin >> address; abs->personArray[abs->m_Size].m_Addr = address; //更新通讯录人数 abs->m_Size++; cout << "添加成功" << endl; system("pause"); system("cls"); } } void showPerson(Addressbooks * abs) { if (abs->m_Size == 0) { cout << "当前记录为空" << endl; } else { for (int i = 0; i < abs->m_Size; i++) { cout << "姓名：" << abs->personArray[i].m_Name << "\t" << endl; cout << "性别：" << (abs->personArray[i].m_Sex == 1 ?
