C语言实现简单通讯录系统
本文实例为大家分享了C语言通讯录系统(增删改查),供大家参考,具体内容如下
全部代码如下所示:
#include <iostream> #include <string> using namespace std; const int MAX = 1000; //联系人结构体 typedef struct person { string m_name; //姓名 int m_sex; //性别 1 男,0 女 int m_age; //年龄 string m_phone; //电话 string m_addr; //住址 }person_t; //通讯录结构体 typedef struct addressbooks { person_t personArray[MAX]; //通讯录中保存的联系人数组 int m_size; //通讯录中人员个数 }addressbooks_t; 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; } void addPerson(addressbooks_t *abs) { //判断通讯录是否满了,如果满了就不再添加 if(abs->m_size == MAX) { cout << "通讯录已满,无法添加!" << endl; return ; } else { //添加具体联系人 cout << "请输入姓名: "; cin >> abs->personArray[abs->m_size].m_name; int sex; while(true) { cout << "请输入性别(1男,0女): "; cin >> sex; if(sex == 1 || sex == 0) { abs->personArray[abs->m_size].m_sex = sex; break; } else { cout << "输入有误,请重新输入!" << endl; } } cout << "请输入年龄: "; cin >> abs->personArray[abs->m_size].m_age; cout << "请输入电话: "; cin >> abs->personArray[abs->m_size].m_phone; cout << "请输入地址: "; cin >> abs->personArray[abs->m_size].m_addr; //更新通讯录人数 ++ abs->m_size; cout << "添加成功!" << endl; system("pause"); } } void displayPerson(addressbooks_t *abs) { if(abs->m_size == 0) { cout << "记录为空!" << endl; } else { cout << "姓名\t" << "年龄\t" << "性别\t" << "电话\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 ? "男" : "女") << "\t"; cout << abs->personArray[i].m_phone << "\t"; cout << abs->personArray[i].m_addr << "\t"; cout << endl; } } system("pause"); } //按姓名查找用户,如果查找到返回联系人在数组中的下标,未查找到返回-1 int findByName(addressbooks_t *abs,string name) { for(int i = 0; i < abs->m_size; ++i) { if(name == abs->personArray[i].m_name) { return i; } } return -1; } void deletePerson(addressbooks_t *abs) { string name; cout << "请输入要删除联的系人姓名:"; cin >> name; int index = findByName(abs,name); if(index == -1) { cout << "通讯录中未查到" << name << endl; } else { for(int i = index; i < abs->m_size; ++i) { abs->personArray[i] = abs->personArray[i+1]; } --abs->m_size; cout << "删除成功" << endl; } system("pause"); } void findPerson(addressbooks_t *abs) { string name; cout << "请输入要查找的联系人姓名:"; cin >> name; int index = findByName(abs,name); if(index == -1) { cout << "通讯录中未查到" << name << endl; } else { cout << "姓名\t" << "年龄\t" << "性别\t" << "电话\t\t" << "地址\t\t" << endl; cout << abs->personArray[index].m_name << "\t"; cout << abs->personArray[index].m_age << "\t"; cout << (abs->personArray[index].m_sex == 1 ?
