What To Do

For your project you will make a utility that can print the contents of an existing tag, if there.

Make a program called exifview and make it so that it runs with the following command line:

$./$exifview FILENAME

It should print the contents of the EXIF tag to the console if present, or give a message if not

present or readable by our program.

Output

Hints and Requirements

$$ We need to treat these files as binary files rather than text files. Make sure to open the

file correctly, and to use fread for I$/$O$.$

$5$

$$ You must use a structure to represent a JPEG$/$TIFF$/$EXIF header and another struct to

represent a TIFF tag. Do NOT use a bunch of disjoint variables. Do your fread$()$ with the

whole structure at once. $($That is$,$ read an entire tag in one file operation.$)$

$$ If the header field does not contain the Exif string in the right place, print an error

message that the tag was not found. If the TIFF header contains MM instead of II$,$ print

an error message that we do not support the endianness.Exif viewer in C$,$
