本文例項為大家分享了C++通訊錄管理系統的具體程式碼,供大家參考,具體內容如下
#include<iostream> #include<string> using namespace std; #define MAX 1000 struct Person { string m_Name; int m_Sex; int m_Age; string m_Phone; string m_Addr; }; struct Addressbooks { struct Person personArray[MAX]; int m_Size; }; void addPerson(Addressbooks * abs) { if (abs->m_Size == MAX) { cout << "通訊錄已滿,無法新增!" << endl; return; } else { string name; cout << "請輸入姓名:" << endl; cin >> name; abs->personArray[abs->m_Size].m_Name = name; cout << "請輸入性別:" << endl; cout << "1 --- 男" << endl; cout << "2 --- 女" << endl; int sex = 0; while (true) { cin >> sex; if (sex == 1 || sex == 2) { abs->personArray[abs->m_Size].m_Sex = sex; break; } cout << "輸入有誤,請重新輸入!" << endl; } cout << "請輸入年齡:" << endl; int age = 0; cin >> age; abs->personArray[abs->m_Size].m_Age = age; cout << "請輸入聯絡電話:" << endl; string phone; cin >> phone; abs->personArray[abs->m_Size].m_Phone = phone; cout << "請輸入家庭住址:" << endl; string address; cin >> address; abs->personArray[abs->m_Size].m_Addr = address; abs->m_Size++; cout << "新增成功" << endl; system("pause"); system("cls"); } } void showPerson(Addressbooks * abs) { if (abs->m_Size == 0) { cout << "當前記錄為空" << endl; } else { for (int i = 0; i < abs->m_Size; i++) { cout << "姓名:" << abs->personArray[i].m_Name << "\t"; cout << "性別:" << (abs->personArray[i].m_Sex == 1 ?
