 T  F    1.   Standard files are always present and do not
              need to be opened or closed.

 T  F    2.   The FILE pointer for standard file names can
              always be used on the left side of an

 T  F    3.   The  **fopen()** function returns a NULL if
              there is a problem opening the file.

 T  F    4.   After opening a file ther is an internal file
              pointer which represents the position within
              the file where the input or output is being

 T  F    5.   Two backslashes are needed inside strings (to
              represent one backslash) because one
              backslash merely indicates that the following
              character is to be taken literally.

 T  F    6.   The  **ftell()** function serves double
              duty, both positioning and reporting position
              within a file.

 T  F    7.   The ANSI standard defines only three standard
              file handles: input, output, and error.

 T  F    8.   The  **extern** keyword is used to provide
              access to variables defined in another source

 T  F    9.   Line input and record input are the same
              thing in C.

 T  F    10.  In binary files any carriage returns that
              appear before a line feed are dropped.

 T  F    11.  The internal file pointer can be positioned
              relative to the first, end or current
              location in the file.

 T  F    12.   **SEEK_SET** is a value passed to the
               **ftell()** function.

 T  F    13.  When reading binary files no changes are
              automatically made to the characters that are

 T  F    14.  The function  **fopen()** returns a NULL if
              the requested file cannot be opened.

 T  F    15.  Line input is not convenient since the input
              lines can be split across two buffers.

 T  F    16.  If a binary file is read as a text file, an
              integer may appear as a carriage return-line
              feed sequence.

 T  F    17.  The  **sizeof** operator should be used
              when reading data to fill a structure.

18. Match the following:

____     int                   A.   open fails if the file
                                       does not exist

____     virtual void xyz()=0;    B.   open a data stream not
                                       attached to any file

____     class B : public A       C.   opens and moves to end
                                       of file

____     ~XYZ() {}                D.   pure virtural function

____     operator+(Str x, Str y); E.   opens the file for read

____     class B : A              F.   open fails if the file
                                       does exist

____     fstream fd;              G.   class destructor

____     protected                H.   a reference variable

____     ios::in                  I.   derived class to access
                                       all sections of base class
                                       as private members

____     ios::ate                 J.   derived class to access
                                       all sections of base class
                                       as public members

____     ios::noreplace           K.   operator overloading

____     ios::nocreate            L.   allows derived classes to
                                       access its members but
                                       works as private to all
