ascii-reverse

Objectives

You must follow the same instructions as in the first subject.

• Ascii-reverse consists on reversing the process, converting the graphic representation into a text.
• You will have to create a text file containing a graphic representation of a random string.
• The argument will be a flag, --reverse=<fileName>, in which --reverse is the flag and <fileName> is the file name.
• The program must print this string in normal text.

This project will help you learn about :

• Client utilities.
• The Go file system(fs) API.
• Ways to receive data.
• Ways to output data.
• Manipulation of strings.
• Manipulation of structures.

Instructions

• Your project must be written in Go.
• The code must respect the good practices.
• It is recommended that the code should present a test file.
