C語言通訊錄系統（增刪改查）

全部代碼如下所示：

#include <iostream> #include <string> using namespace std;const int MAX = 1000;//聯系人結構體 typedef struct person {string m_name; //姓名int m_sex; //性別 1 男，0 女int m_age; //年齡string m_phone; //電話string m_addr; //住址 }person_t;//通訊錄結構體 typedef struct addressbooks {person_t personArray[MAX]; //通訊錄中保存的聯系人數組int m_size; //通訊錄中人員個數 }addressbooks_t;void showMenu() {cout << "************************" << endl;cout << "***** 1.添加聯系人 *****" << endl;cout << "***** 2.顯示聯系人 *****" << endl;cout << "***** 3.刪除聯系人 *****" << endl;cout << "***** 4.查找聯系人 *****" << endl;cout << "***** 5.修改聯系人 *****" << endl;cout << "***** 6.清空聯系人 *****" << endl;cout << "***** 0.退出通訊錄 *****" << endl;cout << "************************" << endl; }void addPerson(addressbooks_t *abs) {//判斷通訊錄是否滿了，如果滿了就不再添加if(abs->m_size == MAX){cout << "通訊錄已滿，無法添加！" << endl;return ;}else{//添加具體聯系人cout << "請輸入姓名： ";cin >> abs->personArray[abs->m_size].m_name;int sex;while(true){cout << "請輸入性別（1男，0女）： ";cin >> sex;if(sex == 1 || sex == 0){abs->personArray[abs->m_size].m_sex = sex;break;}else{cout << "輸入有誤，請重新輸入！" << endl;}}cout << "請輸入年齡： ";cin >> abs->personArray[abs->m_size].m_age;cout << "請輸入電話： ";cin >> abs->personArray[abs->m_size].m_phone;cout << "請輸入地址： ";cin >> abs->personArray[abs->m_size].m_addr;//更新通訊錄人數++ abs->m_size;cout << "添加成功！" << endl;system("pause");} }void displayPerson(addressbooks_t *abs) {if(abs->m_size == 0){cout << "記錄為空!" << endl;}else{cout << "姓名\t" << "年齡\t" << "性別\t" << "電話\t\t" << "地址\t\t" << endl;for(int i = 0; i < abs->m_size; ++i){cout << abs->personArray[i].m_name << "\t";cout << abs->personArray[i].m_age << "\t";cout << (abs->personArray[i].m_sex == 1 ?
