In homework 5, one of the questions required you to determine the execution of a small machine code program that successively changed a register's value. Determining the results of execution for machine code is tedious and error prone because every bit counts and a small mistake can result in wrong answers. Simulators are far better tools for determining execution results at a low level. For low-level programming (machine and assembly languages) we'll be using LC3 Tutor to simulate execution of LC-3 code. The link below takes you to your version of the LC-3 Programming page with instructions about how to use LC3 Tutor. To encourage you to carefully read these instructions, I've placed 3 unusual words in the page, which will seem out of place while reading. Additionally, you'll know it is one of your unusual words because it will have one of its letters underlined. Read the page linked here: LC-3 Programming Confirm you've carefully read the LC-3 Programming instructions linked above by entering in lower case the three unusual words in the order indicated below: A.) Enter the unusual word with its first letter underlined: B.) Enter the unusual word with a middle letter underlined: C.) Enter the unusual word with its last letter underlined:
