用c++做的通讯录管理系统

通讯录管理系统
#include<iostream>
using namespace std;
#include<string>
#define MAX 1000
//发现了两个问题
1、c++中在使用结构体时,不用像c语言一样提前申请空间
2、用c++的string字符串直接接可以做比较,也不用申请空间
//设计联系人结构体
struct Person {
string m_Name;//名字
int m_Sex;//性别 1、男 2、女
//年龄
int m_Age;
//电话
string m_Phone;
//住址
string m_Addr;
};
//设计通讯录结构体
struct Addressbooks {
//通讯录中保存联系人的人数数组
struct Person personArray[MAX];
//通讯录中当前记录的联系人个数
int m_Size;
};
//检测联系人是否存在,如果存在,返回联系人所在数组中的具体位置,不存在返回-1
//参数1 通讯录 参数2 对比姓名
int isExist(Addressbooks* abs, string name)
{
for (int i = 0; i < abs->m_Size; i++) {
//找到用户输入的姓名了
if (abs->personArray[i].m_Name == name)
{
return i;//找到了,返回这个人在数组中的下表编号
}
}
return -1;//如果遍历结束没找到,返回-1
}
//1、添加联系人
void addPerson(Addressbooks * abs)
{
//判断通讯录是否已满,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
//姓名
string name;
cout << "请输入姓名:" << endl;
cin >> name;
abs->personArray[abs->m_Size].m_Name = name;
//性别
cout << "请输入性别:" << 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 << "输入有误,请重新输入" << endl;
}
//年龄
cout << "请输入年龄:" << endl;
int age = 0;
cin >> age;
abs->personArray[abs->m_Size].m_Age = age;
//电话
cout << "请输入联系电话:" << endl;
string phone;
cin >> phone;
abs->personArray[abs->m_Size].m_Phone = phone;
//住址
cout << "请输入家庭住址:" << endl;
string address;
cin >> address;
abs->personArray[abs->m_Size].m_Addr = address;
//更新通讯录人数
abs->m_Size++;
cout << "添加成功!" << endl;
system("pause");
system("cls");//清屏
}
}
//2、显示联系人
void showPerson(Addressbooks* abs)
{
//判断通迅录中人数是否为0,如果为0,提示记录为空
//如果不为0,显示记录的联系人信息
if (abs->m_Size == 0) {
cout << "当前记录为空!" << endl;
}
else {
for (int i = 0; i < abs->m_Size; i++) {
cout << "姓名: " << abs->personArray[i].m_Name << "\t";
cout << "性别: " << (abs->personArray[i].m_Sex == 1 ? "男" : "女") << "\t";
cout << "年龄: " << abs->personArray[i].m_Age << "\t";
cout << "电话: " << abs->personArray[i].m_Phone << "\t";
cout << "地址: " << abs->personArray[i].m_Addr << endl;
}
}
system("pause");
system("cls");
}
//3、删除指定的联系人
void deletePerson(Addressbooks* abs)
{
cout << "请输入你要删除的联系人" << endl;
string name;
cin >> name;
//ret == -1 未查到
//ret !=-1 查到了
int ret = isExist(abs,name);
if (ret != -1)
{
//查找到人,要进行删除操作
for (int i = ret; i < abs->m_Size; i++) {
//数据前移
abs->personArray[i] = abs->personArray[i + 1];
}
abs->m_Size--;//更新通讯录中的人员数
cout << "删除成功" << endl;
}
else {
cout << "查无此人" << endl;
}
system("pause");
system("cls");
}
//4、查找指定的联系人
void findPerson(Addressbooks* abs)
{
cout << "请输入你要查找的联系人" << endl;
string name;
cin >> name;
//判断指定的联系人是否存在通讯录中
int ret = isExist(abs, name);
if (ret != -1) {
cout << "姓名: " << abs->personArray[ret].m_Name << "\t";
cout << "性别: " << (abs->personArray[ret].m_Sex == 1 ? "男" : "女") << "\t";
cout << "年龄: " << abs->personArray[ret].m_Age << "\t";
cout << "电话: " << abs->personArray[ret].m_Phone << "\t";
cout << "地址: " << abs->personArray[ret].m_Addr << endl;
}
else {
cout << "查无此人" << endl;
}
//按任意键,清屏
system("pause");
system("cls");
}
//5、修改指定联系人信息
void modifyPerson(Addressbooks* abs)
{
cout << "请输入你要修改的联系人" << endl;
string name;
cin >> name;
//判断指定的联系人是否存在通讯录中
int ret = isExist(abs, name);
if (ret != -1) {
//姓名
string name;
cout << "请输入姓名:" << endl;
cin >> name;
abs->personArray[ret].m_Name = name;
//性别
cout << "请输入性别:" << endl;
cout << "1----男" << endl;
cout << "2----女" << endl;
int sex = 0;
while (true) {
cin >> sex;
if (sex == 1 || sex == 2)
{
abs->personArray[ret].m_Sex = sex;
break;
}
cout << "输入有误,请重新输入" << endl;
}
//年龄
cout << "请输入年龄:" << endl;
int age = 0;
cin >> age;
abs->personArray[ret].m_Age = age;

abs->personArray[ret].m_Addr = address;
}
else {
cout << "查无此人" << endl;
}
//按任意键,清屏
system("pause");
system("cls");
}
//6、清空所有联系人
void cleanPerson(Addressbooks* abs)
{
abs->m_Size = 0;//将当前记录联系人数量置为0,做逻辑清空操作
cout << "通讯录已清空" << endl;
system("pasue");
system("cls");
}
//菜单界面
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;
}
int main()
{
//创建通讯录结构体变量

//初始化通讯录中人员个数
abs.m_Size = 0;
int select = 0;//创建用户输入变量
while (true) {
//调用菜单
