制作一个具有添加联系人、删除联系人、修改联系人等功能的通讯录系统
效果图:
代码如下:
#include <iostream>using namespace std;#include <string>#define Max 1000//创建联系人结构体struct person{ string p_name; int p_sex; //1、男 2、女 int p_age; string p_phone; string p_address;};//创建通讯录结构体struct addressbooks{ //保存的联系人数组 struct person personarr[Max]; //当前记录的人数 int p_size;};//菜单void showmenu() { 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 << "********************************" << endl;} //添加联系人void addperson(addressbooks* abs){ //先判断通讯录是否已满 if (abs->p_size == Max) { cout << "通讯录已满" << endl; return; } else { string name; cout << "请输入姓名: " << endl; cin >> name; abs->personarr[abs->p_size].p_name = name; cout << "请输入性别: " << endl; cout << "输入1 -- 男" << endl; cout << "输入2 -- 女" << endl; int sex = 0; while (true) { cin >> sex; if (sex == 1 || sex == 2) { //输入1或者2,退出循环. 输入其他数字重新循环 abs->personarr[abs->p_size].p_sex = sex; break; } cout << "请重新输入" << endl; } } //年龄 cout << "请输入年龄" << endl; int age = 0; cin >> age; abs->personarr[abs->p_size].p_age = age; //电话 cout << "请输入联系电话" << endl; string phone; cin >> phone; abs->personarr[abs->p_size].p_phone = phone; //地址 cout << "请输入地址" << endl; string address; cin >> address; abs->personarr[abs->p_size].p_address = address; //更新通讯录 abs->p_size++; cout << "添加成功" << endl; system("pause"); system("cls");} //显示联系人void showperson(addressbooks* abs){ if (abs->p_size == 0) { cout << "当前联系人为空" << endl; } else { for (int i = 0; i < abs->p_size; i++) { cout << "姓名: " << abs->personarr[i].p_name << "\t"; cout << "性别: " << (abs->personarr[i].p_sex == 1 ?
