Implementing a program that recovers JPEGs from a forensic image

Specification

Implement a program called recover that recovers JPEGs from a forensic image.

Implement your program in a file called recover.c in a directory called recover.

• Program should accept exactly one command-line argument, the name of a forensic image from which to recover JPEGs
• Program is not executed with exactly one command-line argument, it should remind the user of correct usage, and main should return 1.
• If the forensic image cannot be opened for reading, program should inform the user as much, and main should return 1.
• If it uses malloc, program must not leak any memory.

Pseudocode

• Open Memory card
• Repeat until end of card: Read 512 bytes into a buffer If start of new JPEG ... Else ... Else If already found JPEG ...

• The function grayscale should take an image and turn it into a black-and-white version of the same image.
• The function sepia should take an image and turn it into a sepia version of the same image.
