0417檔案輸出輸入ifstream (檔案輸入)、ofstream (檔案輸出) 以及 fstream (檔案輸出入)
※檔案的開啟與關閉
開啟檔案
檔案物件.open(“檔案名稱”,ios::開啟模式);
可供選擇的開啟模式
- ios::app 開啟可供附加資料的檔案
- ios::in 開啟可供讀取資料的檔案
- ios::out 開啟可供寫入資料的檔案
- ios::trunc 若檔案已存在，先刪除它，再開啟
- ios::binary 開啟二進位的輸入/輸出檔案
關閉檔案
檔案物件.close();
※文字檔的處理
將資料寫入文字檔
將資料附加到已存在的文字檔
從文字檔案讀取資料
get()、getline()、put()
利用 put() 將字串寫入檔案
文字檔的拷貝與讀取
//從檔案內讀取一個字元，並把它寫入 ch 字元變數
檔案物件.get(ch);
//從檔案內最多讀取 N-1 個字元，或是讀取到 \n
//並把它存放到字串 str 中
檔案物件.getline(str, N, ’\n’);
//將ch字元變數的值寫入檔案內
檔案物件.put(ch);
