通讯录管理系统
通讯录管理系统
1.系统需求
通讯录是一个可以记录亲人、好友信息的工具
本教程主要利用c++来实现一个通讯录管理系统
系统中需要实现的功能如下:
1.添加联系人:向通讯录中添加新人,信息包括(姓名、性别、年龄、联系电话、家庭住址)最多纪录1000人
2.显示联系人:显示通讯录中所有联系人的信息
3.删除联系人:按照姓名进行删除指定联系人
4.查找联系人:按照姓名查看指定联系人信息
5.修改联系人:按照姓名重新修改指定联系人
6.清空联系人:清空通讯录中所有信息
7.退出通讯录:退出当前使用的通讯录
2.创建项目
新建项目
3.菜单功能
功能描述:用户选择功能的界面
步骤:封装函数显示该界面, 如void showMenu()
在main函数中调用封装好的函数
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;
return;
}
4.退出功能
功能描述:退出通讯录系统
思路:根据用户的不同选择,进入不同的功能,可以选择switch分支结构。将整个构架进行搭建
当用户选择0时,执行退出,选择其他先不做操作,也会退出程序。
5.添加联系人
功能实现:实现添加联系人功能,联系人上限为1000人,联系人信息包括(姓名、年龄、联系电话、家庭住址)
添加联系人实现步骤:
1、设计联系人结构体
2、设计通讯录结构体
3、main函数中创建通讯录
4、封装添加联系人函数
5、测试添加联系人函数
void addPerson(Addressbooks *abs) {
if (abs->m_size == MAX_N) {
cout << "通讯录已满,无法添加!";
return;
}
else {
string name;
cout << "请输入姓名:" << endl;
cin >> name;
abs->personArray[abs->m_size].name = name;
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;
}
cout << "请输入年龄:" << endl;
cin >> abs->personArray[abs->m_size].m_Age;
cout << "请输入联系电话:" << endl;
cin >> abs->personArray[abs->m_size].m_phone;
cout << "请输入家庭住址:" << endl;
cin >> abs->personArray[abs->m_size].m_adder;
abs->m_size++;
cout << "添加成功!" << endl;
system("pause");//请按任意键继续
system("cls");//清屏操作
}
return;
}
6.显示联系人
功能描述:显示通讯录中已有的联系人信息
显示联系人实现步骤:
封装显示联系人函数
测试显示联系人功能
void showperson(Addressbooks *abs) {
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].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 << "住址:" << abs->personArray[i].m_adder << endl;
}
cout << "信息显示完成!" << endl;
}
system("pause");//请按任意键继续
system("cls");//清屏操作
return;
}
7.删除联系人
功能描述:按照姓名进行删除指定联系人
删除联系人实现步骤:
1.封装检测联系人是否存在
2.封装删除联系人函数
3.测试删除联系人功能
int isExist(Addressbooks *abs, string name) {
for (int i = 0; i < abs->m_size; i++) {
if (abs->personArray[i].name == name) {
return i;
}
}
return -1;
}
void selectperson(Addressbooks *abs) {
string name;
cout << "请输入删除的联系人姓名:" << endl;
cin >> name;
int ret = isExist(abs, name);
if (ret == -1){
cout << "查无此人!" << endl;
}
else {
for (int i = ret; i < abs->m_size; i++) {
abs->personArray[i] = abs->personArray[i + 1];
}
abs->m_size--;
cout << "删除成功!" << endl;
}
system("pause");//请按任意键继续
system("cls");//清屏操作
return;
}
8.查找联系人
功能描述:按照姓名查看指定联系人信息
查找联系人实现步骤:
1.封装查找联系人函数
2.测试查找指定联系人
void findperson(Addressbooks *abs) {
string name;
cout << "请输入要查找的联系人:" << endl;
cin >> name;
int ret = isExist(abs, name);
if (ret != -1) {
cout << "姓名:" << abs->personArray[ret].name << "\t" << "性别:" << (abs->personArray[ret].m_Sex == 1 ? "男" : "女") << "\t"
<< "年龄:" << abs->personArray[ret].m_Age << "\t" << "电话:" << abs->personArray[ret].m_phone << "\t"
<< "地址:" << abs->personArray[ret].m_adder << endl;
}
else {
cout << "未找到此人!" << endl;
}
system("pause");//请按任意键继续
system("cls");//清屏操作
return;
}
9.修改联系人
功能描述:按照姓名重新修改指定联系人
修改联系人实现步骤:
1.封装修改联系人功能
2.测试修改联系人功能
void modifyperson(Addressbooks *abs) {
cout << "请输入要修改的联系人姓名:" << endl;
string name;
cin >> name;
int ret = isExist(abs, name);
if (ret != -1) {
string name1;
cout << "请输入姓名:" << endl;
cin >> name1;
abs->personArray[ret].name = name1;
cout << "请输入性别:" << endl;
cout << "1——男" << endl;
cout << "2——女" << endl;
int sex = 0;
while (true) {
cin >> sex;
