電話簿（檔案儲存）
阿新 • • 發佈：2018-12-22
相比於動態儲存，用資料夾儲存聯絡人資訊需要改變的有以下幾點：
1.將聯絡人資訊存入檔案
{ FILE* fp = fopen("../test.txt","w"); int i = 0; printf("儲存聯絡人資訊...\n"); if(fp == NULL) { printf("檔案開啟失敗，儲存失敗！\n"); return; } for(i = 0; i<phonebook.size; i++) { fwrite(&phonebook.contact[i], sizeof(Contact), 1, fp); } fclose(fp); printf("儲存成功！共儲存了%d條資訊！\n",phonebook.size); }
2.聯絡人資訊載入
void load() { FILE* fp = fopen("../test.txt","r"); Contact tmp = {0}; printf("載入聯絡人資訊...\n"); if(fp == NULL) { printf("檔案開啟失敗，儲存失敗！\n"); return; } while( fread(&tmp, sizeof(tmp), 1, fp) ) { CheakRealloc(); phonebook.contact[phonebook.size] = tmp; phonebook.size++; } fclose(fp); printf("載入成功！共載入了%d條資訊！\n",phonebook.size); }
3.在主函式中，初始化電話簿後需要載入聯絡人資訊；在每次改動聯絡人資訊後儲存聯絡人資訊：
int main() { int input = 0; Init(); load(); do { menu();//列印選單 printf("請輸入操作序號："); scanf("%d",&input); clean(); switch(input) { case 1: AddContact(); save(); break; case 2: DelContact(); save(); break; case 3: ModifyContact(); save(); break; case 4: FindContact(); break; case 5: PrintContact(); break; case 6: CleanContact(); save(); break; case 0: printf("歡迎下次使用~~\n"); break; default: printf("輸入序號有誤，請重新輸入！\n"); break; } } while(input); return 0; }
完整程式碼如下：
test.c
#define _CRT_SECURE_NO_WARNINGS 1
#include "PhoneBook.h"
//列印選單函式
void menu()
{
printf("┏━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━┓\n");
printf("┃ 歡迎使用電話簿 ┃\n");
printf("┣━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━┫\n");
printf("┃ 1.新增聯絡人 2.刪除聯絡人 ┃\n");
printf("┣━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━┫\n");
printf("┃ 3.修改聯絡人 4.查詢聯絡人 ┃\n");
printf("┣━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━┫\n");
printf("┃ 5.檢視所有聯絡人 6.清空電話簿 ┃\n");
printf("┣━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━┫\n");
printf("┃ 0.退出電話簿 ┃\n");
printf("┗━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━┛\n");
}
//主函式
int main()
{
int input = 0;
Init();
load();
do
{
menu();//列印選單
printf("請輸入操作序號：");
scanf("%d",&input);
clean();
switch(input)
{
case 1:
AddContact();
save();
break;
case 2:

save();
break;
case 3:

save();
break;
case 4:
FindContact();
break;
case 5:
PrintContact();
break;
case 6:
CleanContact();
save();
break;
case 0:
printf("歡迎下次使用~~\n");
break;
default:
printf("輸入序號有誤，請重新輸入！\n");
break;
}
}
while(input);
return 0;
}
