大家可以先下载一下这篇文章的资源绑定的exe文件(免费),体验下通讯录是如何运行的。

整体思路
- 显示菜单
- 创建通讯录的结构体(嵌套联系人的结构体数组+联系人个数)
- 根据菜单建立选择分支
- 完善各个分支的内容
int main()
{
//创建通讯录结构体变量
Addressbooks abs;
//初始化通讯录中当前人员个数
abs.m_Size = 0;
int select = 0;//选择
while (true)
{
//菜单调用
menu();
cout << "选择功能(0-6)" << endl;
cin >> select;
switch (select)
{
//1.添加联系人
case 1:
addPerson(&abs);//利用地址传递可以修饰实参
break;
//2.显示联系人
case 2:
showPerson(&abs);
break;
//3.删除联系人
case 3:
deletePerson(&abs);
break;
//4.查找联系人
case 4:
findPerson(&abs);
break;
//5.修改联系人
case 5:
modifPerson(&abs);
break;
//6.清空联系人
case 6:
cleanPerson(&abs);
break;
//0.退出通讯录
case 0:
cout << "欢迎下次使用" << endl;
system("pause");//按下任意键退出代码
return 0;
break;

如果写在同一个文件中,会十分拥挤,我们可以新建一个函数定义的文件在源文件(后缀.cpp)中,函数声明的文件在头文件(后缀.h)中。
