Answer the following statements true (T) or false (F)

1. An istream object is already an ifstream object with some extra, added features. 2. When you write ifstream inStream; inStream.open(”infile.dat”); the file, infile.dat must be located in the directory where the program is being run. 3. When you use the open member function to tie a file name to a file stream, the file name is called the external file name, and the program refers to the file by the stream name. 4. A file is automatically closed when a program terminates, so there is never a need to close a file. 5. The flush member function copies the file buffer to the file on the file medium (disk, tape, etc).
