A file stream, fStr, is open and attached to physical file.txt. To reset this file stream so that the file can be read again starting at the first line requires

a) “File stream fStr, reset yourself to the start of the file.”
b) Calling the reset() member function using fStr as the calling object but with
no argument.
c) With calling object fStr call close()then call open( ) with argument
“fStr”.
d) Only calling the member function open() using fStr as the calling object with
the “file.txt” as argument.
e) None of the above. You can’t reread lines of a file that have already been read.

c) With calling object fStr call close()then call open( ) with argument
“fStr”.
