ascii conversion table

This post was inspired because of my continual attempts to reference ASCII characters and codes in my beginning work of learning C and bash at bootcamp School. I simply wanted an easy way to reference the codes and characters, but also share a simple conversion table with no garbage advertisements and slow loading content. Additionally, through my process of researching ASCII characters and codes, I discovered a neat ASCII art website that creates ASCII art text for you. Since I integrated the tool and the art I generated from it into my website, I'll give a shoutout to the creator (or host, I'm not sure) of the ASCII art generator: patorjk.com/software/taag. Patrick Gillespie! Thank you!

Alternative to this blog post, if you are familiar with command line to run bash and shell commands, type $ man ascii to read the manual on ascii, and a list of all the ascii characters. The following is an exerpt of part of the manual for ascii in ubuntu 14.04.5:

$ man ascii
