C++ 通讯录管理系统

通过C++设计的一个通讯录管理系统，能实现对联系人的添加，显示，删除，查找，修改，清空的作用。

 int result = checkPerson(abs, fname);
 if (result == -1)

int main(void)

 //创建通讯录结构体变量
 addreassbooks abs;

 abs.m_Size = 0;

 int select = 0;
 while (1)
 {
  mainMenu();
  cin >> select;
  switch (select)
  {
  case 1://添加联系人
   addPerson(&abs);
   break;
  case 2://显示联系人
   printPerson(&abs);
   break;
  case 3://删除联系人
   deletePerson(&abs);
   break;
  case 4://查找联系人
   findPerson(&abs);
   break;
  case 5://修改联系人
   modifyPerson(&abs);
   break;
  case 6://清空联系人
   cleanPerson(&abs);
   break;
  case 0://退出通讯录
   cout << "欢迎下次使用" << endl;
   system("pause");
   return 0;
  default:
   break;
  }
 }
}

通过创建这个通讯录管理系统让我们把学过的所有知识都联系在了一起，我感觉这一个通讯录管理系统最重要的就是你要学会熟练的运用结构体和对函数的递归调用。在涉及到对联系人的显示，删除，查找，修改功能时基本上每一步都需要用到查找联系人的函数，先判断联系人是否存在，然后再对其进行操作。
这一个通讯录管理系统是一个很好的例子，要想掌握好一门语言就必须要能熟练的写出这个基础的通讯录管理系统，我们要把这个程序的每一个步骤都弄懂，为更深层次的学习打下坚实的基础。
