String fileName is a file's name read from input. The opened file, fileName, contains the number of shelves ordered from a

wholesaler by various retailers. The file is associated with the stream inFS. Use a loop to iterate until the end of the file, and

perform the following tasks:

Read the next string from the opened file.

Read the next integer from the opened file.

If no error occurs in the previous two read operations, then output the string followed by $"$ purchased $",$ the integer,

$"$ shelves.", and a newline.

int shelfquantity;

cin $>>$ fileName;

inFS $.$open$($fileName$)$;

if $(!$inFS.is$\_$open$())\{$

cout $$ fileName : program exiting due to file error" $$ endl;

return $1$ ;

$\}$

$/*$ Your code goes here $*/$

inFS.close$()$;

return $0$ ;
