Description

added a link to a tutorial for creating an LC2K learning tool using C, added to the end of the C/C++ section

Motivation and Context

I noticed some tutorials especially OS related but none that actually aid in teaching assembly in a simplified manner.

How Has This Been Tested?

I ran my code through a compiler and the output was the expected result for each piece of example code

I ran my tests through GDB online, and hardcoded inputs to test certain components
