本文例項為大家分享了C++實現連結串列版本通訊錄的具體程式碼,供大家參考,具體內容如下
#include <iostream> #include <string> using namespace std; class Address; class Contact{ private: string name; string sex; string tel; string QQ; string address; string addition; Contact *next; public: Contact(); friend class Address; }; Contact::Contact() { next = NULL; } class Address{ public: Address(); ~Address(); int show(); void insert(); void delete_per(); void display(); void search(); void update(); private: Contact *head; }; Address::Address() { head = new Contact; if(head == NULL) { cout<<"fail create"<<endl; } } Address::~Address() { delete head; } int Address::show() //主選單函式 { int choice = 0 ; cout<<"\t\t\t\t**************************"<<endl; cout<<"\t\t\t\t* 通訊錄c++簡易版本 *"<<endl; cout<<"\t\t\t\t**************************"<<endl; cout<<"\t\t\t\t* 1、新增 2、刪除 *"<<endl; cout<<"\t\t\t\t**************************"<<endl; cout<<"\t\t\t\t* 3、檢視 4、搜尋 *"<<endl; cout<<"\t\t\t\t**************************"<<endl; cout<<"\t\t\t\t* 5、更新 6、退出 *"<<endl; cout<<"\t\t\t\t**************************"<<endl; cout<<"\t\t\t\t請輸入選擇:"; cin>>choice; while(!(choice >= 1&&choice <= 6)) { while(getchar()!='\n'); cout<<"輸入有誤,請重新輸入!"; cin>>choice; } return choice; } void Address::insert() //新增聯絡人 { Contact *p = head; char relay = 0; while(p->next != NULL) { p = p->next; } Contact *person = new Contact; cout<<"請輸入姓名:"; cin>>person->name; cout<<"請輸入性別:"; cin>>person->sex; cout<<"請輸入電話:"; cin>>person->tel; cout<<"請輸入QQ:"; cin>>person->QQ; cout<<"請輸入住址:"; cin>>person->address; cout<<"請輸入備註:"; cin>>person->addition; p->next = person; person->next = NULL; cout<<"\n新增成功,是否繼續新增?(y/n)"; cin>>relay; while(!(relay == 'y'||relay == 'Y'||relay == 'N'||relay == 'n')) { cout<<"輸入錯誤,請重新輸入(y/n):"; cin>>relay; } if(relay == 'y'||relay == 'y') { system("clear"); insert(); } } void Address::delete_per() //刪除聯絡人 { string m_name; Contact *p = head; Contact *pre = head; int flag = 0; cout<<"請輸入你要刪除的聯絡人姓名!"; cin>>m_name; while(p->next != NULL) { pre = p; p = p->next; if(p->name == m_name) { pre->next = p->next; delete p; p = NULL; flag = 1; break; } } if(flag == 1) { cout<<"刪除成功!"<<endl; } else { cout<<"您刪除的聯絡人不存在,刪除失敗!"<<endl; } } void Address::display() //檢視聯絡人 { Contact *p = head; while(p->next != NULL) { p = p->next; cout<<endl<<"======================================="<<endl; cout<<"姓名:"<<p->name<<endl; cout<<"性別:"<<p->sex<<endl; cout<<"電話:"<<p->tel<<endl; cout<<"QQ:"<<p->QQ<<endl; cout<<"地址:"<<p->address<<endl; cout<<"備註:"<<p->addition<<endl; } } void Address::search() //搜尋聯絡人 { string m_name; Contact *p = head; int flag = 0; cout<<"請輸入你要搜尋的聯絡人姓名:"; cin>>m_name; while(p->next != NULL) { p = p->next; if(p->name == m_name) { cout<<endl<<"======================================="<<endl; cout<<"姓名:"<<p->name<<endl; cout<<"性別:"<<p->sex<<endl; cout<<"電話:"<<p->tel<<endl; cout<<"QQ:"<<p->QQ<<endl; cout<<"地址:"<<p->address<<endl; cout<<"備註:"<<p->addition<<endl; flag = 1; } } if(flag == 1) { cout<<"\n查詢成功!"<<endl; } else { cout<<"您查詢的聯絡人不存在,刪除失敗!"<<endl; } } void Address::update() //修改聯絡人 { Contact *p = head; string m_name; int flag = 0; cout<<"請輸入你要更新的姓名:"; cin>>m_name; while(p->next != NULL) { p = p->next; if(p->name == m_name) { cout<<"請更新性別:"; cin>>p->sex; cout<<"請更新電話:"; cin>>p->tel; cout<<"請更新QQ:"; cin>>p->QQ; cout<<"請更新住址:"; cin>>p->address; cout<<"請更新備註:"; cin>>p->addition; flag = 1; break; } } if(flag == 1) { cout<<"\n更新成功"<<endl; } else { cout<<"查無此人,更新失敗!"<<endl; } } int main() { Address *person = new Address; int choice = 0; while(1) { system("clear"); choice = person->show(); switch(choice) { case 1: { system("clear"); person->insert(); break; } case 2: { system("clear"); person->delete_per(); break; } case 3: { system("clear"); person->display(); break; } case 4: { system("clear"); person->search(); break; } case 5: { system("clear"); person->update(); break; } case 6: { exit(0); } } cout<<"\n\n按任意鍵返回....."; getchar(); getchar(); } return 0; }
