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:
