The class mantains internally (privately) a pointer to a filebuf in charge of the interaction with the file. This pointer can be obtained/modified by calling member ruf. The file to be processed can be specified as a parameter for the constructor or by calling member open. After a file is processed it can be closed by calling member close. In this case the file stream may be used to open another file. Member is_open can be used to detene wether the stream is currently operating on a file or not. Please refer to parent classes for more details on information mantained by an ofstream object. */ //使用(C++庫)ofstream寫檔案資料 //simple example #include #include using namespace std; #ifdef #define TEST_FILE "c:tmptest.txt" #else #define TEST_FILE "/tmp/test.txt" #endif void test() { //ofstream ofs; //ofs.open(TEST_FILE); ofstream ofs(TEST_FILE); char ch =
