该项目非常适合新手c++的同学来做(当然也包括我)，先看一个通讯录管理系统需要写什么东西。
学习于：https://www.bilibili.com/video/BV1et411b73Z?p=75（自我感觉讲的超级棒）
其中值得注意的是调用函数需要传值时，如果不需要改变实参 直接传值就好了，如果需要改变实参，必须得传指针(也就是传址)
然后还有个注意的点就是结构体和结构体指针变量的使用，剩下的就敲代码了！
得达到上图这些功能，成功之后菜单栏显示如下所示
下面就是各个小块的代码：
主函数,头文件和结构体的构造函数的代码会放在最后面
菜单栏的代码
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;
}
1.添加联系人
void addPerson(Addressbooks* abs)
{
if (abs->m_size == MAX)
{
cout << "通讯录已满" << endl;
return;
}
else
{
//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 << "请输入电话:" << endl;
string phone;
cin >> phone;
abs->personArray[abs->m_size].m_Phone = phone;
//地址
cout << "请输入地址：" << endl;
string address;
cin >> address;
abs->personArray[abs->m_size].m_Adds = address;
}
//更新通讯录人数
abs->m_size++;
cout << "添加成功！！！" << endl;
system("pause"); //请按任意键继续
system("cls"); //清屏操作
}
2.显示联系人
void showPerson(Addressbooks* abs)
{
assert(abs != NULL);
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 << "\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_Adds << endl;
}
}
system("pause"); //请按任意键继续
system("cls"); //清屏操作
}
下面有个判断输入名字是否在数组中的一个函数，在后面的函数中都会用到
int isExist(Addressbooks* abs, string name)
{
for (int i = 0; i < abs->m_size; i++)
{
if (abs->personArray[i].m_Name == name)
{
return i;
}
}
return -1;
} //查找到的话 返回的是该名字在数组中的下标3.删除指定联系人
void deletePerson(Addressbooks* abs)
{
cout << "请输入要删除的联系人姓名：" << endl;
string name;
cin >> name;
int ret = isExist(abs, name);
if (ret != -1)
{
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;
}
else
{
cout << "查无此人" << endl;
}
system("pause"); //请按任意键继续
system("cls"); //清屏操作
}4.查找指定联系人信息
void findPerson(Addressbooks* abs)
{
cout << "请输入您要查找的联系人：" << endl;
string name;
cin >> name;
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 << "\t";
cout << "年龄：" << abs->personArray[ret].m_Age << "\t";
cout << "电话：" << abs->personArray[ret].m_Phone << "\t";
cout << "住址：" << abs->personArray[ret].m_Adds << endl;
}
else
{
cout << "查无此人" << endl;
}
system("pause"); //请按任意键继续
system("cls"); //清屏操作
}
5.修改联系人
void modifyPerson(Addressbooks* abs)
{
cout << "请输入要修改的联系人：" << endl;
string name;
cin >> name;
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;
//电话
cout << "请输入电话:" << endl;
string phone;
cin >> phone;
abs->personArray[ret].m_Phone = phone;
//住址
cout << "请输入地址：" << endl;
string address;
cin >> address;
abs->personArray[ret].m_Adds = address;
cout << "修改成功" << endl;
}
else
{
cout << "查无此人" << endl;
}
system("pause"); //请按任意键继续
system("cls"); //清屏操作
}6.清空通讯录列表
void clearPerson(Addressbooks* abs)
{
abs->m_size = 0;
cout << "清除成功" << endl;
system("pause"); //请按任意键继续
system("cls"); //清屏操作
}
主函数：
int main()
{
int select = 0; //创建用户输入的选择
Addressbooks abs;
abs.m_size = 0;//初始化联系人个数
while (true)
{
//菜单调用
ShowMenu();
cin >> select;
switch (select)
{
case 1:
//showPerson(&abs);
addPerson(&abs); //利用地址传递，达到修改实参
break;
case 2:
showPerson(&abs);
break;
case 3:
deletePerson(&abs);
break;
case 4:
findPerson(&abs);
break;
case 5:
modifyPerson(&abs);
break;
case 6:
break;
case 0:
cout << "欢迎下次使用" << endl;
system("pause");
return 0;
break;
default:
break;
}
}
system("pause");
return 0;
} 头文件包含和结构体设计：
#include<iostream>
using namespace std;
#include<string>
#include<assert.h>
#define MAX 1000
//设计联系人结构体
struct Person
{
string m_Name;
int m_Sex;//1.男，2.女
int m_Age;
string m_Phone;
string m_Adds;
};
//设计通讯录结构体
struct Addressbooks
{
struct Person personArray[MAX]; //联系人数组
int m_size; //记录通讯录中联系人个数
};
