C++程序学习之实现手机通讯录功能模拟

摘要：本文实现了使用C++程序代码模拟手机通讯录功能，有添加，删除，修改联系人等功能，这是一个入门C++时写的的命令行模拟程序，并非界面程序实现！

• 代码如下：

  • 主函数

  //main.cpp
  
  #include"Edit_contect.h"
  
  using namespace std;
  int main()
  {
  //Part 1:main Interface
  for (int i = 0; i < 30; i++){ cout << " " << "*"; }cout << endl;
   cout << " *                        Contects                         *" << endl;
   cout << " *                                                         *" << endl;
   cout << " *          1.Add_contect           2.View_contectlist     *" << endl;
   cout << " *                                                         *" << endl;
   cout << " *          3.Delete_contect        4.Save_contect         *" << endl;
   cout << " *                                                         *" << endl;
   cout << " *          5.Edit_contect          6.Close_contect        *" << endl;
   cout << " *                                                         *" << endl;
   cout << " *                                                         *" << endl;
   cout << " *                                                         *" << endl;
   cout << " *         Attention：You have to ADD CONTECTS first for   *" << endl;
   cout << " *                                                         *" << endl;
   cout << " *                    using other functions correctly！    *" << endl;
   cout << " *                                                         *" << endl;
   cout << " *                    You can add 15 contects at most.     *" << endl;
   for (int i = 0; i < 2; i++){ cout << " " << "*" << "                                                         " << "*" << endl; }
   for (int i = 0; i < 30; i++){ cout << " " << "*"; }cout << endl;
  
  //Part 2: functions
   int  Noun = 1;
   cout << "Please choose the function you need：  ";
   cin >> Noun;
   while (Noun != 6)//loop structure
   {
    if (Noun == 1) { Add_contect(); cout << "Please choose the function you need：  "; cin >> Noun; }//this funcion for adding contect
    else if (Noun == 2){ View_contect(); cout << "Please choose the function you need：  "; cin >> Noun; }//this funcion for viewing contect
    else if (Noun == 3){ Delete_contect(); cout << "Please choose the function you need：  "; cin >> Noun; }//this funcion for deleting contect
    else if (Noun == 4){ Save_contect(); cout << "Please choose the function you need：  "; cin >> Noun; }//this funcion for showing all contects
    else if (Noun == 5){ Edit_contect(); cout << "Please choose the function you need：  "; cin >> Noun; }//this funcion for editting contect
   }
   if (Noun == 6){ cout << "Successfully to stop!" << endl; }
  
   //Part 3: Over
   system("pause");
   return 0;
  }

  • 添加联系人

  //Add_contect.h:

   for (int i = 1; i < 20; i++)
   {
    if (i <= 15)
    {
     cout << "NAME " << i << " :  ";
     cin >> NAME[i];
     if (i >= 2)

     if (N == 1)
     {
      NAME[i] = NAME[i + 1];
      NUMBER[i] = NUMBER[i + 1];
      CATEGORY[i] = CATEGORY[i + 1];
      EMAIL[i] = EMAIL[i + 1];
      cout << "Deleting finished!" << endl;
     }
     else break;
     cout << "1.Go on 2.Return  ";
     cin >> N;
     if (N == 2)break;
     else if (N == 1)continue;
     else { cout << "ERROR!"; break; }
    }
   }
  }

  • 保存联系人

  //Save_contect.h
  //this part for saving contects
  
  #include

   if (Save_file.is_open())
   {
    for (int i = 1; i <= 15; i++)
    {
     if (!NAME[i].empty())
     {
