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 Interfacefor (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://this part for adding contects#include#include#includeusing namespace std;string NAME[15];string NUMBER[15];string CATEGORY[15];string EMAIL[15];string info[15];void Add_contect(){ int GOON = 1; cout << "Input contect's NAME  TELEPHONE_NUMBER  CATEGORY  EMAIL" << endl; cout << "Attention:Input ONE item at a time!" << endl; for (int i = 1; i < 20; i++) {  if (i <= 15)  {   cout << "NAME " << i << " :  ";   cin >> NAME[i];   if (i >= 2)   {    for (int k = 1; k <= 15; k++)    {     if (NAME[i] == NAME[k]){ cout << "Contact  already exists!Please enter another contect: "; i = i - 1; break; }     else     {      cout << "TELEPHONE_NUMBER " << i << " :  ";      cin >> NUMBER[i];      cout << "CATEGORY " << i << " :  ";      cin >> CATEGORY[i];      cout << "EMAIL " << i << " :  ";      cin >> EMAIL[i];      break;     }    }   }   cout << "GO ON?  1.YES  2.NO" << endl;   cin >> GOON;   if (GOON == 2)break;   else if (GOON == 1)continue;  }  else cout << "There is no extra space!" << endl; }}

  • 删除联系人

  //Delete_contect.h//this part for deleting contects#include"View_contect.h"void Delete_contect(){ string NAME1; int N; for (int i = 1; i <= 15; i++) {  cout << "Input the name you want to delete(ONE NAME AT A TIME): 　" << endl;  cin >> NAME1;  if (NAME1 == NAME[i])  {   cout << "Are you sure to delete the infomation of " << NAME1 << ". 1.YES   2.NO " << endl;   cin >> N;   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#include#include"Delete_contect.h"void Save_contect(){ ofstream Save_file; Save_file.open("E:\\contect.txt"); if (Save_file.is_open()) {  for (int i = 1; i <= 15; i++)  {   if (!NAME[i].empty())   {    Save_file << i << NAME[i] << NUMBER[i] << CATEGORY[i] << EMAIL[i];   }   Save_file.close();   Save_file.close();  }  cout << "Saving contects finished!" << endl; } else cout << "Can't create file contect.txt" << endl;}

  • 编辑联系人

  //Edit_contect.h//this part for editing contects#include#include"Save_contect.h"void Edit_contect(){ string name2; int N, M; for (int i = 1; i <= 15; i++) {  cout << "Input the name you want to edit:  ";  cin >> name2;  if (name2 == NAME[i])  {   cout << "which item do you want to edit?   1." << NAME[i] << "   2." << NUMBER[i] << "   3." << CATEGORY[i] << "   4." << EMAIL[i] << endl;   cin >> N;   if (N == 1){ cout << "Input new name:  "; cin >> NAME[i]; }   else if (N == 2){ cout << "Input new number:  "; cin >> NUMBER[i]; }   else if (N == 3){ cout << "Input new category:  "; cin >> CATEGORY[i]; }   else if (N == 4){ cout << "Input new email:  "; cin >> EMAIL[i]; }   else { cout << "ERROR!"; break; }   cout << "new item has been saved!" << endl;  }  else { cout << "ERROR!"; break; }  cout << "Go on?  1.Yes  2.No  ";  cin >> M;  if (M == 1)continue;  else if (M == 2)break;  else  cout << "ERROR!"; break; }}             

  • 查看联系人

  //View_contect.h                                         // this part for viewing contects#include#include"Add_contect.h"void View_contect(){ char category; cout << "Please choose category（A、B or C)(A.办公类 B.个人类 C.商务类):  "; cin >> category; if (category == 'A') {  int N = 1;  for (int i = 1;; i++)  {   if (CATEGORY[i] == "办公类"){ cout << N << "  " << NAME[i] << "  " << NUMBER[i] << endl; N++; }   else if (i > 15) break;  } } else if (category == 'B') {  int N = 1;  for (int i = 1;; i++)  {   if (CATEGORY[i] == "个人类"){ cout << N << "  " << NAME[i] << "  " << NUMBER[i] << endl; N++; }   else if (i > 15)break;  } } else if (category == 'C') {  int N = 1;  for (int i = 1;; i++)  {   if (CATEGORY[i] == "商务类"){ cout << N << "  " << NAME[i] << "  " << NUMBER[i] << endl; N++; }   else if (i > 15)break;  } }}
