c++通讯录管理系统

结构体1，知识点（结构体），存放人员详情，名字，性别，年龄等 struct person { string m_name; int m_sex; int m_age; string m_phone; string m_addr; }; 结构体2，知识点 （结构体数组），存放人员数量和人员数组 struct addressbooks { struct person personarray[MAX]; int m_size; }; 上面两个结构体存放我们的数据，我们基于这两个结构体操作 菜单界面，用于输入提示 void showMenu() { 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 << "*****7.退出通讯录*****" << endl; } 主函数循环测试输入并跳转函数 知识点，cin输入，switch选择

增删改查之添加 判断人数是否满，满了直接退出 人数没有满通过结构体2抽象出人员表进行添加操作 知识点->结构体指针访问 .结构体访问 a->b[人员数量].具体参数 完了之后人员数要+1防止数据覆盖 void addperson(addressbooks *abs) { if(abs->m_size==MAX) { cout <<"通讯录已满,不能再添加!" <<endl; return; } else { //姓名输入 string name; cout << "请输入姓名"<< endl; cin >>name; abs->personarray[abs->m_size].m_name=name; //性别输入 int sex=0; cout << "请输入性别"<< endl; cout << "输入1为男"<< endl; cout << "输入2为女"<< endl; while (true) { cin >> sex; if(sex==1||sex==2) { abs->personarray[abs->m_size].m_sex=sex; break; } else { cout <<"输入错误,请重新输入" << endl; break; } } //年龄输入 int age=0; cout << "请输入年龄"<< endl; cin >>age; if( age>=0 && age<=150 ) abs->personarray[abs->m_size].m_age=age; else cout << "你不是地球人"<< endl; //电话输入 string phone; cout << "请输你的电话号码"<< endl; cin >> phone; abs->personarray[abs->m_size].m_phone=phone; //地址输入 string address; cout << "请输你的住址"<< endl; 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"); } } 增删改查之删除 输入字符串通过isExist查找返回结构体数组下标 然后把结构体数组地址全部前移 人员总数减去1 isExist函数本体在下面 //删除指定联系人 void deletePerson(addressbooks *abs) { cout << "请输入您要删除的联系人" << endl; string name; cin >> name; int ret =isExist(abs,name); if(ret!=-1) { for(int i=ret;i<abs->m_size;i++) { abs->personarray[i]=abs->personarray[i+1]; } abs->m_size--;//更新人员数 cout << "删除成功" << endl; } else { cout << "查无此人" << endl; } system("pause"); system("cls"); } isExist函数本体 遍历数组，对照结构体1的名字成员，返回下标 int isExist(addressbooks * abs,string name) { for(int i=0; i <abs->m_size; i++) { if(abs->personarray[i].m_name==name) { return i; } } return -1; } 增删改查之修改（看源码理解，没有新知识点） void revampPerson(addressbooks* abs) { cout << "请输入您要修改的联系人" << endl; string name; cin >> name; int ret =isExist(abs,name); if(ret!=-1) { cout <<"新名字修改为"<< endl; string new_name; cin >> new_name; abs->personarray[ret].m_name=new_name; cout <<"性别修改为"<< endl; int new_sex; cin >> new_sex; abs->personarray[ret].m_sex=new_sex; cout <<"年龄修改为"<< endl; int new_age; cin >> new_age; abs->personarray[ret].m_age=new_age; cout <<"家庭住址修改为"<< endl; string new_addr; cin >> new_addr; abs->personarray[ret].m_addr=new_addr; cout <<"电话修改为"<< endl; string new_phone; cin >> new_phone; abs->personarray[ret].m_phone=new_phone; } else { cout << "查无此人" << endl; } system("pause"); system("cls"); } 增删改查之总体查询（看源码理解，没有新知识点） void showPerson(addressbooks * abs) { if(abs->m_size==0) { cout << "记录为空" << endl; } else for(int i=0;i<abs->m_size;i++) { cout <<"姓名"<<abs->personarray[i].m_name<<"\t"; cout <<"性别"<<(abs->personarray[i].m_sex==1 ? "男":"女")<<"\t"; cout <<"年龄"<<abs->personarray[i].m_age<<"\t"; cout <<"电话"<<abs->personarray[i].m_phone<<"\t"; cout <<"住址"<<abs->personarray[i].m_addr<<endl; cout<<endl; cout<<endl; } system("pause"); system("cls"); } 增删改查之单独查询（看源码理解，没有新知识点） void findPerson(addressbooks* abs) { string name; cout <<"请输入你要查找的联系人名字"<<endl; cin >> name; int ret =isExist(abs,name); if(ret!=-1) { cout<<"名字 : "<<abs->personarray[ret].m_name<<"\t"; cout<<"年龄 : "<<abs->personarray[ret].m_age<<"\t"; cout<<"住址 : "<<abs->personarray[ret].m_addr<<"\t"; cout<<"电话 : "<<abs->personarray[ret].m_phone<<"\t"; cout<<"性别 : "<<(abs->personarray[ret].m_sex==1?"男":"女")<<endl; } else { cout << "查无此人" << endl; } system("pause"); system("cls"); } 学习记录，源码评论区获取
