| Sorry, I forgot to change the initial description that the number of reds, blues, and greens will be 4. However, the code should be correct...-Ashley |
| Prof. Guzdial, what specifically do we have to know about sound. I know there was mention of it in recitation but I do not see anything in the review. REMOVEDk lists, tracing code, writing code, ect.? |
| Why do the initial number or reds, blues, and green need to be 4? Is the code above correct? -Neal |
