[問題] 雜七雜八的問題...

[james0419 (阿富)]

1.  為什麼我每次cout一個file都會出現一個類似記憶體位置的東西      例:ox22fed8

2.我再寫一個class的constructor十,發現只要我把那些commwent的東西comment掉的

話,就可以順利印出整個檔案的內容


  class PrintOut{
public:
PrintOut(char* name):_ifs(name,ios::in|ios::out){cout<<_ifs;
//_file=new char[sizeof _ifs];
//_ifs.write(_file,sizeof _ifs);
}

.......


PrintOut p("sdf.txt");

while(p._ifs.get()!=EOF)
cout<<p._ifs.get();   //Read a file
cout<<endl<<endl;
p._ifs.close();




例如:

推 ric2k1:為什麼是 cout 一個 file (或是 fstream) 呢? 你應該是弄錯
→ ric2k1:fstream 的用法了... 應該是: 1. 宣告變數 (是檔案內容
→ ric2k1:而定), 2. 用 fstream 將檔案內容讀到變數上, 3. cout
→ ric2k1:該變數 ==> 這樣才是你想要的吧! 而且注意一下 get() 的
→ ric2k1:return type 哦!
